How Much Oil Capacity Does Honda 160cc Lawn Mower Can Has?

A lawnmower engine runs on oil, similar to many combustion engines. Though it is a straightforward machine, it is purposely crafted to run even on immensely top speed and intense heat. That’s why an engine needs oil to run the moving parts smoothly.

What is the Honda 160cc lawn mower engine oil capacity?

A Honda 160cc lawn mower engine can hold up to 0.58 quarts of oil (18.6 ounces). When the oil amount drops to 12 to 13.5 ounces, you should refill it to ensure smooth mowing operation.

What is the Honda 160cc lawn mower engine oil capacity?

Though car engines and lawnmowers have different structures, they function similarly. That’s why it is essential to change the oil of a lawnmower engine for optimum operation.

So, when should you change your lawn mower‘s oil, and how much oil should you refill for your lawnmower? Your lawn mower engine oil capacity depends on its engines size and its model.

For example, the Honda 160cc lawn mower engine oil capacity is around 0.58 quarts of oil (18.6 ounces). You should neither overfill it nor keep the oil level too low.

Generally, in order to prevent any harm to the internal parts of a lawnmower, you want to change the oil in a lawnmower every 20-50 hours. As you don’t need to face any hassle to change the oil, you can do it on your own.

So, why should you not exceed your Honda 160cc lawn mower engine oil capacity?

Exceeding your engine oil capacity means you are overfilling it. Overfilling a lawnmower engine may affect the engine performance negatively. Overfilling may cause the transformation of oil from the engine to the air filter and air cleaner area.

How will you know whether you have overfilled your Honda 160cc lawn mower engine or not? When you overfill a lawnmower engine, you will notice blue or white is coming from the engine while using your mower to cut grass.

How Much Oil Does A Honda Lawn Mower Hold?

As a gardener, you must know the amount your Honda lawn mower can hold. Though their Honda lawn mower comes in different horsepower engines, most of them have similar oil capacity.

How much oil does a Honda lawn mower hold?

A Honda mower can typically hold 18.6 ounces. But you want to remember that a high horsepower motor works quickly and efficiently than a low horsepower motor. That’s why you need to change the oil of high horsepower earlier than lower horsepower motors.

So, you now know how much oil does a Honda lawn mower hold. Though most Honda lawnmowers have almost similar oil capacity, their performance varies based on weather conditions and the amount of oil inside them. That’s why you want to keep the optimum amount of oil without overfilling it.

What Type Of Oil Should I Use For My Honda Lawn Mower?

Petroleum Based Motor Oils are the best choice for most Honda Lawnmowers. But this type of oil comes in different types as per weather conditions and other factors. Mainly, there are four types of lawnmower oil.

In addition, most Honda lawnmowers have four-stroke engines. Apart from choosing a particular type of engine oil, you need the right oil based on temperature conditions.

For example, you can’t use the same oil for excessively high temperatures that you can use for colder temperatures.

How your mower engine performs depends on weather conditions too. Because of it, try to keep the engine at the best possible conditions for the desired performance you want from it.

Here we are mentioning some best types of oil you should use for different temperatures.

Weather Conditions Type Of Oil You Should Use

How Much Oil Does A Honda Gcv160 Lawn Mower Take?

The Honda Gcv160 Lawn Mower is mainly a 4-stroke engine, which is perfect for residential purposes. Its fuel tank capacity is 0.98 U.S. quarts of oil (0.93 liters). This powerful machine can take a heavy load of grass cutting with consistent performance.

How much oil does a Honda gcv160 lawn mower take?

As with some 4-stroke engines, the Honda gcv160 lawn mower can hold up to 0.58 US quarts of oil (0.55 liter). With this amount of oil, you can run the lawnmower for several days. After running your lawnmower for several days (20-50 hours of usage), you can refill or change the oil to optimum engine performance.

So, knowing how much oil does a Honda gcv160 lawn mower helps you determine your engine oil capacity and when you should change the oil.

When You Should Change Your Honda Lawn Mower Oil?

There is no scope to know how much oil is remaining in a two-stroke engine. However, four-stroke Honda Lawn engines have the accessibility to know how much oil is left.

Check your lawn’s engine oil before each cutting session and top it off if needed. Garden experts recommend changing your lawn mower oil after the first 3-5 hours of use if the machine is entirely new.

Though most manufacturers include oil in the engine, the oil level often gets lower as they test the machine’s performance. That’s why they tell their customers to change the oil as early as possible.

Besides, since new engines initially wear out their parts, metal filings are released into the oil during the internal movement of parts. As a result, leaving it, there will result in excess wear.

The perfect time for changing lawnmower oil depends on the lawnmower type. Two types of Honda Lawnmowers are mainly available in the market.

Some Best Lawn Mowers Using 160cc Honda® engine

Best Riding Lawn Mowers. Craftsman 17ARFACQ091

If you have a walk-behind mower, change the oil a minimum of one time for each season or at least after 50 hours of usage.

On the other hand, if you are using a riding mower, at least a one-time seasonal oil change is required. If you are using it heavily, count 100 hours of usage and change it after 100 hours.

Most Honda lawn mowers have manual instructions where it is clearly stated how much oil you can fill for your engines. Additionally, every four-stroke lawnmower engine includes an oil level mark or dipstick, letting you know when you should change the oil.

What Happens If You Run A Honda Lawn Mower Without Oil?

As you have already known, a lawnmower engine functions just like a car engine. Just like car engines, lubrication is also needed for lawn mower engines. The motor of a lawnmower uses oil to lubricate the internal components.

What happens if you run a Honda lawn mower without oil?

It is possible to run your Honda lawn mower without oil. But running your Honda lawn mower without oil will cause wear out or damage issue for the internal parts. Gradually, you will notice performance deterioration for your lawnmower engine. In addition, low oil level indicators are found on some lawnmowers; the mower won’t start unless you refill or change the oil.

Can You Use Regular Motor Oil In A Lawn Mower?

Yes, you can use regular motor oil in a lawnmower if your lawnmower has a four-stroke engine. In general, regular motor oil is okay for lawnmowers with four-stroke engines.

However, it is best to check the instruction manual to know if the engine is compatible with the oil or any mentioned prohibition for a particular oil type.

Some automobile engine oils are only designed to use for large engines as they have excessive viscosity. As a result, it isn’t always better to have more.

In addition, some models of Honda riding mowers and push mowers are allowed to use regular motor oil. However, if the models have a two-stroke engine, you can’t use regular motor oil. It is because they required a mixture of oil and fuel in a specific portion due to their small engines.

BEFORE You BREAK IN Your New Lawn Mower Engine, WATCH THIS!

What Is The Best Oil For A Honda Lawn Mower?

No one knows better which type of oil you should use for your lawnmower than the manufacture. Hence, always follow your manufacture’s recommendation to add oil.

Using different oils may be necessary, as we discussed earlier, based on weather conditions, engine type, etc.

Here we are mentioning few best oils for Honda lawn mowers:

Oil Name Temperature Conditions Type
Briggs Stratton 30W Engine Oil 40°-100°F SAE 30W
Honda 08207-10W30 PK2 Motor Oil all-temperatures 10W-30
Pennzoil (550034991-6PK) SAE 30 Motor Oil all-temperatures SAE 30
STP 18589 Oil high temperatures SAE-30
Castrol 03093 GTX all-temperatures 10W-30

Final Thought

It is essential to know your Honda 160cc lawn mower engine oil capacity. You can refill or change the oil according to it. It is vital that you regularly change the oil in your engine so that it can perform at its best. If you take too much time to change the oil, it may lead to damage to the internal moving parts. Ultimately, your maintenance cost will increase. So, treat your lawnmower wise properly to cut grass precisely.

The Best Self-Propelled Lawn Mowers in 2023 for Making Your Yard Work Easier

These lawn mowers drive themselves, taking the load off you in the process.

By Roy Berendsohn Published: Mar 21, 2023

One of the perks of the warm-weather season is getting to spend time outside. If you own your own home and have a yard, it’s very likely that in order to enjoy your outdoor space, you need to mow the lawn. The larger the yard, the more work it will be to maintain. If you have a lot of grass to cut, you’d be wise to consider a self-propelled lawn mower especially now that there are a ton of sales just in time for Memorial Day.

The primary difference between a standard push mower and a self-propelled mower is that the former moves when you push it, and the latter essentially moves itself with only your guidance. Once the engine is running, all you have to do is squeeze a handle or push a lever and the mower will start moving forward with you as you walk.

Turning the mower around is your job, but once you have your heading, just keep the drive handle squeezed and escort the mower down the path, no pushing necessary.

Self-propelled law mowers take power off the engine and route it via a belt to a pulley on the transmission and axle. When you move the drive control lever on the mower handle, you tension the belt, causing the pulley to turn, and this drives the transmission, moving the mower forward.

Move the drive control lever back and the tension is released, the pulley stops turning, and the mower stops moving forward. The belt-driven transmission is a time-tested design to power the mower and take the load off you in the process.

What to Consider

A mower is like many consumer products in that the more features a manufacturer adds, the more expensive it becomes. But a longer or more eye-catching list of features isn’t necessarily better. Sometimes less is more. Here are the most important to keep in mind.

Front-wheel drive mowers tend to be less expensive than rear-wheel drive units. They can be easier to turn because you don’t have to disengage the drive wheels to do so. Simply push down on the handlebar to raise the front wheels off the ground. However, their traction isn’t as strong on hills or when the bag is full, as there isn’t as much weight over the drive wheels.

Rear-wheel drive mowers do cost more and aren’t as easy to turn, as you do need to disengage the drive—but this isn’t too much of a hassle. Rear-wheel drive mowers shine on hills and inclines, and when the grass bag is full. In either scenario, weight is shifted rearward and over the drive wheels, which enables superior traction, thus making the self-propel more effective.

An engine as small as 125 cc can power a mower, but most are somewhere in the 140 cc to 190 cc range. A large engine helps when powering through tall, lush grass or in extreme conditions, such as with a side discharge chute in place and mowing tall weeds in a border area. Also, the extra torque provided by a larger engine can improve bagging when the going gets tough (tall, leaf-covered grass in the fall). But if you mow sensibly and pay attention to deck height—and especially if you don’t let your lawn get out of control—an engine between 140 and 160 cc has more than enough power to get the job done.

A mower can have all four wheels the same diameter (7 to 8 inches), or it may have rear wheels that range from 9.5 inches to 12 inches in diameter. Larger rear wheels help the mower roll more easily over bumpy ground.

With some mowers you can start the engine with the twist of a key or the press of a button. It’s a great option, but a luxury. Keep the mower engine tuned and use fresh fuel with stabilizer added to it, and you’ll never have trouble starting.

Any number of mechanisms can control a mower’s ground speed—a squeeze handle, a drive bar that you press forward, even a dial. There’s no single right answer here. Look at the design and think about how you like to work. For example, if more than one person will be using the mower (and not all of them are right-handed), a drive control like that on a Toro Personal Pace mower might be the answer. Just push down on the bar to make it go faster. Let up on the bar to slow down.

A mower that can bag, mulch, and side discharge is known as a three-function mower, the most versatile kind. Two-function mowers bag and mulch or mulch and side discharge.

Mowers will typically have one, two, or four levers to control the deck height. Single-lever adjustment is the easiest to use, but it requires more linkage, which adds weight and complexity. If, for some reason, you find yourself varying deck height frequently, it’s a good option. Otherwise, two or four levers work just fine.

Only Honda makes a gas-engine mower with a high-impact plastic deck (there are battery mowers that have plastic decks). Otherwise, mowers generally have a steel deck, and a few manufacturers—Toro, for one—offer a corrosion-resistant aluminum deck. An aluminum deck won’t rot the way a steel deck will, but you still need to keep it clean.

This is a hose fitting mounted on top of the mower’s deck. When you’re done mowing, hook up a hose and run the mower to power wash the underside of the deck. We’ve had mixed results with these, but they’re better than just letting a mass of dried grass clippings accumulate.

expensive mowers come with a more durable bag with more dust-blocking capability. If you bag a lot, especially leaves or other lawn debris in the fall, then you need a mower with a higher quality dust-blocking bag. Having said that, if you rarely bag, the standard one that comes with a mower will last you the life of the mower.

Also called wide-area mowers, machines in this subgroup help homeowners better reconcile their need for more power and speed with the fact that they may not have enough storage for a tractor or zero-turn mower. A typical residential walk mower has a single-blade deck that cuts a swath from 20 to 22 inches wide. Wide-cut mowers (built for homeowner use) have either a single blade or, more typically, a pair of blades, cutting from 26 to 30 inches with each pass. Some of these are rated for light commercial use and have larger decks, in the 32-inch range, and engines that start at 223 cc and go up to about 337 cc.

Wide-cut mowers typically employ gear or hydrostatic drive transmissions, and they have top speeds of about 4 to 6 miles per hour. At their fastest, they move so quickly you have to trot to keep up with them. Needless to say, they’re overkill for small yards; only opt for one of these if you’ve got a significant plot of land that you need to keep tidy, but not one so large that you’d be better off going with a full-on riding mower.

How We Tested and Selected

We compiled this list based on Popular Mechanics mower testing and our knowledge of the lawn mower market at large. For our testing, we put mowers through the paces using our standard Popular Mechanics methodology: We cut turf grasses such as fescues and blue grass and rougher non-turf grasses like Timothy, clover, orchard grass, and wild oats, all in both normal and shin-deep heights. We mow uphill, downhill, and across the faces of hills. The maximum slope we cut is about 30 degrees.

That may not sound like much, but it’s about all you can do to stand on it, let alone push a mower up it or across it. We mow damp and wet grass to test general cutting performance and whether clippings accumulate on the tires. And we cut dry and dusty surfaces to see how well the bag filters under less-than-optimal conditions.

Honda HRN 216VKA

Key Specs

Honda mowers enjoy a sterling reputation. Having tested their walk and self-propelled mowers for the last 30 years, we feel confident that Honda’s entry level mower is a great choice for homeowners looking for power and durability. The HRN features a GCV 170 gas engine that’s built to withstand long hours of operation.

If you do your own maintenance (and most owners who buy this class of product do), you’ll appreciate the easily accessible spark plug and the fuel shutoff valve that enables better winter storage. Close the fuel shutoff and run the mower until it sputters to a halt. This will clear the carburetor of any gasoline, which will prevent the ethanol in it from disintegrating and causing running issues later on. Open the shutoff valve in the spring, add some fresh gasoline, and the mower should start easily.

All this maintenance stuff is great, but we can also tell you that our past test findings on other Hondas prove that their cut quality is outstanding for cleanliness. Sharp blades deliver a velvet-like finish. And their bagging ability is also quite good, in the same league with other well-bagging mowers from Toro.

In all, if you take mowing seriously, you should enjoy this Honda. If you have a little wiggle room in your budget, consider the Honda HRX, which features a mower powerful engine and a composite deck that won’t rust and is renowned for its durability.

One note is that Honda has announced that it will cease selling lawn mowers in the United States after this year—so if you’re considering buying one, best do it sooner rather than later.

Toro Recycler 60-Volt Max Lithium-Ion

Key Specs

Toro mowers have garnered more recommendations from us than any other brand for two reasons: build quality and cut quality. These were amply demonstrated in our testing as the Recycler turned in the best ratio of cut area per amp-hour of battery in the self-propelled category, while at the same time not skimping on cutting, mulching, or bagging quality.

We attribute this outstanding mower performance to three features, all upgrades to the previous version of this machine. First, the air vent at the front of the mower deck seems to improve mulching and bagging performance. Toro calls it Vortex technology, a design that increases air flow under the deck. This helps to stand the grass for a cleaner cut, which improves mulching performance, and also allows better airflow into the bag when collecting the clippings.

Next, the company’s redesigned “Atomic” blade configuration appears to assist the air flow and clipping movement. Finally, the three-phase, 60-volt motor is exceptionally efficient, resulting in a large cut area for a single battery.

Toro has maintained features that make this mower work: rear wheel drive, a one-piece deck that’s all steel (no plastic nose), 11-inch wheels to help it roll over roots and crevices, and the same fold-forward handle that was an industry breakthrough when it was introduced some years ago.

Ryobi 40-Volt Brushless Self-Propelled Mower

Key Specs

This is one of Ryobi’s top-of-the-line mowers, and it’s American-made construction is something we wish we saw more of. It delivers a tremendous cut area with its two 6-Ah batteries providing a total of 12-Ah of capacity, and its X-shaped blade leaves a pristine surface in its wake.

Ryobi estimates the design should provide 70 minutes of run time; we didn’t time our cut, but it strikes as plausible. Its rear-wheel drive and reasonably aggressive tire tread pattern provide good hill climbing and sidehill cutting performance, and its bagging on all surfaces (level, sidehill, and uphill) is also commendable.

Other ease-of-use features include an easily installed or removed bag that mounts and dismounts straight up and down through the handle; deck adjustment is quick and easy thanks to a single-level deck height adjustment. The straight edge deck is polypropylene; it will never rust and needs very little care other than basic cleaning.

Toro TimeMaster 30 in. Briggs Stratton Personal Pace

The Toro Timemaster 30-in. mower has been around for several years and has earned a reputation as a sturdy workhorse for homeowners who want to cut down on their mowing time. It’s also used by some professionals as well. A few years ago the Timemaster got a slightly more powerful Briggs and Stratton gas engine, so it should have no issues powering through most demanding mowing jobs.

gcv170, honda, mower

The Timemaster is rear-wheel drive and features Toro’s Personal Pace drive system that’s used on many of its self-propelled mowers. This allows the mower to move at your speed by simply pushing down or releasing the handle, which is spring-tensioned.

With a 30-in. deck, Toro claims the Timemaster will help you reduce your mowing time by about 40% compared to using a standard-sized mower. You can mulch, back, or side discharge with the Timemaster, and the handlebar can be locked in a fully vertical position to reduce space consumption in storage.

If you have half an acre to a full acre of lawn to mow and prefer the experience of a walk-behind mower versus a tractor or zero-turn, the Timemaster is worth a look.

Craftsman M220

Key Specs

Craftsman mowers have been doing very well in our tests, so we can recommend this one because it’s so much like the many other of the brand’s models that we’ve tested. If you’re looking for a good blend of maneuverability and power, you’ll get it with this mower. Its front drive helps move it along and makes it easy to turn.

It’s important to note that front-drive mowers do lose some traction when running uphill, particularly with a full grass bag. But if your slope is less than 20 degrees, and you’re not bagging uphill, you’ll be fine. The side discharge will also help you handle tall grass. Adjust the two deck levers to bring the mower up to full height and have at the rough stuff.

The fact that this mower bags, mulches, and side discharges is a plus, enabling you to handle a wide range of mowing conditions, from early spring and late into the fall. Three-function mowers like this are our preference for that versatility.

Toro Super Recycler Self-Propelled Lawn Mower

Key Specs

This is a beauty of a mower, with a cast-aluminum deck and a smooth-running Briggs Stratton 163-cc engine. We tested the Honda engine-equipped version, and it was effective at both bagging and mulching, even in moist grass.

Equipped with rear-wheel drive and the Personal Pace system (the farther you push the drive bar, the faster the mower goes), it’s an effective hill climber and moderately effective on sidehill cutting. It has relatively small 7.5-inch tires on all four corners, which causes this Toro to bump up and down a bit on washboard surfaces. But the good news is that it’s equipped with a far higher quality tire than we’re used to seeing these days. We didn’t notice them pick up any grass on moist surfaces.

Other features we like include its forward-fold handle that has a built-in shock absorber that Toro calls a Flex Handle Suspension, and a high-quality grass bag that loads through the handle, from the top.


Are there special maintenance considerations with self-propelled mowers?

Yes. Both front- and rear-wheel drive mowers typically feature a drive belt, which can crack or wear out over time. Fortunately these belts are not difficult or particularly expensive to replace.

Secondly, you may have to replace the drive wheels occasionally. These wheels are driven with gears. there are typically teeth on the inside diameter of the drive wheel that line up with a gear on the axle. These teeth can wear out, especially if they are made of plastic. Higher-end mowers may feature drive wheels with a metal gear that meets the metal axle gear, which improves longevity of these components.

My lawnmower says I don’t ever have to change the oil, but just add oil when needed. Is this OK?

It’s not a good idea to never change the oil in your lawn mower. In a lawn mower, same as a car, oil degrades over time and is less effective at reducing heat and friction in metal components. Changing the oil in your lawn mower is easy to do and will significantly increase its service life. For most homeowners, changing the oil at the beginning or end of each mowing season should be sufficient, though there is certainly no harm in doing it more often.

Why Honda Lawn Mower Leaking Oil From The Bottom

When it comes to lawn mowing, imagine catching a fire on the grass, slowly spreading across the space with no such solutions in sight. Pretty scary and dark, right?

In order to prevent these thoughts from turning into reality, just like our good and old “Final Destination” movies, we must know about our oil leaks in a lawn mower. Luckily enough, if you own a lawn mower from Honda, this one’s made just for you!

As expected, you may ask why a Honda lawn mower is leaking oil from the bottom? In brief, if the seal of the lower bearing ring or the valve gasket are worn out, they will start to seep out loads of oil and are in dire need of immediate repair or replacement.

However, let’s know a bit about the troubles of such oil leakages before getting into business, shall we?

Troubles from Having an Oil leak in a Lawn Mower

often than ever, we seem to overlook the stroke of sheer bad luck that oil leaks bring with it. Don’t forget to take a quick look into such troublesome occurrences before hopping into the next section!

  • Damage to the engine and internal parts
  • Emitting of white or bluish smoke from the
  • Spark plug might burn and turn engine off
  • Air filter will get contaminated and exhaust the engine
  • Mower muffler gets clogged and arises risk of noise and ignition
  • Fuel runs out faster and destroy the internals
  • Carburetor will act up and mower will not start

Sourcing the Oil Leak

The first and foremost requirement to saving yourself from a fire mishap is to locate and repair the oil leakage source. But before you get into the trickier part, you need to do the basics.

Hence, let’s continue and look into two of the best ways for the task.

The Traditional Way

Firstly, scrub the engine block with a soft cloth and if needed, a clean toothbrush, to get rid of any residual debris and oil. Once this has been settled, turn the engine on and let it run for a while. Lastly, switch it off and look for any traces of oil drops and leaks.

UV Leak Detector Kit

Another not-so-conventional way is to get your hands on this fine device, which is a UV leak detector kit. It comes with an array of items such as a UV light source, a pair of glasses, a dye injector as well as a fluorescent dye to do the main job of detection.

Simply follow the instructions provided on the user manual of the kit and you’ll be done in a jiffy!

Bottom Leakage?

Now, leaks can stem from a variety of points, be it the base of the engine, near the bottom of the deck, or the crankcase breather, you just name it.

However, the most common of them all is when the oil starts to seep out through the oil tank and floods the engine base or the deck. To confirm whether the oil leak sources from the bottom of your Honda lawn mower, use the above methods in a careful manner and check for any signs of holes at the bottom.

Given that the suspicions are right, you know it’s high time to get it repaired or replaced.

Why Honda Lawn Mower is Leaking Oil from Bottom

Lower Bearing

The ring seal on the lower bearing, also known by an oil seal, helps in fastening the crankshaft and causes the blade of your lawn mower to spin heftily.

Whenever this ring seal is in tatters, oil will directly seep into your engine. And once this happens, your carburetor will fail to efficiently induce combustion due to lack of fuel and eventually cause gas to leak out and damage your Honda mower.

However, one thing to keep in mind is to always keep in check whether the carburetor is tilted upwards, otherwise the gas leak is inevitable.

In case you’re suspecting the lower bearing ring seal to be the underlying cause of oil leakage, simply examine the engine in the “traditional” way to look out for leaks and repair it immediately.

gcv170, honda, mower

For the best scrutinization, keep eyes on the seals right after you have switched on the lawn mower as the oil’s viscosity reduces while cooling down and offers poorer examining.

Upper Bearing

Given that you notice oil deposition on the deck on your Honda lawn mower, the significant reason behind it may be the upper bearing’s ring seal being damaged or broken.

Your next question might be, “But where is this seal so I can locate the leak easily?” Well, you can simply find this upper bearing ring seal on the meeting point of the crankshaft plunging into the crankcase breather.

Due to the continuous rotation of the crankshaft, this seal seems to wear off with time. Nevertheless, poor conditions such as extreme dirt and debris accumulated in the engine can cause them to deteriorate much faster.

For better inspection of oil leaks, be certain to take off the engine shroud and starter initially and then move on to the flywheel with the proper tools needed. Likewise, move on to the repair or replace work and you’ll be good to go.

Valve Gasket

A specifically important part on a Honda lawn mower or any other in general is the head or valve gasket. For common knowledge, the seal on this valve gasket aids in air-tightening the connection between the valve cover and its chamber.

And once this seal gets worn out with days passing by or even more sadly, has blown off, oil will leak off heavily. The end result? Your mower will power down and start to function poorly, especially on bumps and hills.

Hence, if and when this happens, make sure to follow the above guidelines to check for oil buildup or leaks and get it replaced right away!

Repair or Replace

Herein comes the vital part of our discussion. Should we repair the oil leaks on our Honda lawn mower or do we replace the parts without a second thought?

To be frank, this entirely depends upon the circumstances. Nonetheless, our best advice for such situations is to get them replaced, if not impossible to do so at the moment. The reason behind this is quite simple- safety always comes first! After all saving a life should be counted as more than saving a few bucks anyway.

Hence, unless it’s really necessary, don’t even bother to go through the repair techniques that we’re about to put forth and get the parts replacement immediately.

Repairing the Gasket

This part is pretty straightforward. Just remove the bolts from the gasket cover and use a scraper to take off every bit of oil buildup as well as the worn out gasket. Then install a new one carefully without harming the engine. Be certain to follow the owner’s manual to repair in accordance to the torque specs established by the manufacturer.

Repairing the Seals

To get the seals repaired, firstly locate the exact seal which keeps seeping out all oil.

For the upper seal, simply remove the motor shroud, crank rotator and flywheel respectively and take off the seal.

Even so, the lower bearing seal repair will require you to remove the engine beforehand. Be sure to drain the engine of oil, unfasten all the cables as well as take off the mower blade and deck cover prior to unbolting the engine.

Once taken care of, use a seal remover tool or a screwdriver to detach the seal from either the upper bearing or the lower bearing. Then install a new one by simply pressing it firmly and reassembling the rest of the parts into place.

Pro-tip: Avoid under- or over-tightening the fasteners to prevent possible oil leaks in the future.

Maintaining a beautiful lawn can be a daunting task, especially if you lack the appropriate know-how and tools to handle the challenges that may crop up. Fortunately, LawnAsk is here to offer you an all-encompassing resource that covers everything you need to know about lawn care.
