When buying a tiller, you want to be sure that it will serve for a long time, carefully and effectively performing all the functions assigned to it. Undoubtedly, the quality of the unit is a crucial aspect when choosing a tiller. However, it is worth remembering that the timely and proper maintenance of the mechanism is a guarantee of its durability and efficiency. No machine will serve you faithful service if you do not take care of him, changing consumables in time, tightening the necessary nuts, checking the oil level.
Any tiller owner wondered about replacing oils for tiller. I want to do this according to all instructions so that further work of the unit would occur without failures and malfunctions. So, in our article, we will tell you what kind of oil should be used and how to change the oil in the tiller.
To begin, consider the three main questions about oil for diesel tiller with a cooling water system:
1) how to fill and check the oil level in the crankcase
2) how to fill and check the oil level in the gear housing
3) how to pour oil into the air filter.
First of all, it is necessary to install the tiller on a flat horizontal surface. Next, you need to clean the surface around the neck for pouring oil into the engine crankcase (in the figure below, you can see where it is located).
After that. unscrew the cap-dipstick for filling the oil and fill the required amount of oil with the help of a watering can-funnel. With the help of the dipstick, you can check its level. To do this, wipe the dipstick dry, insert the plug-probe into the filler neck, without twisting it along the threads, remove the plug-probe and make sure that the oil level is between the “minimum” and “maximum” marks. In the figure below, you will see how to work with the probe.
Now tightly tighten the cap probe.
Please note: if you check the oil level in the tiller on a warm engine or gearbox, you must wait a few minutes after stopping. So the oil will flow back into the crankcase cavity, and the check will show the correct result.
Having installed the tiller on a flat horizontal surface, clean the gearbox housing near the plastic plug of the filler hole located under the steering wheel mounting bracket and near the bolt of the control hole located on the right side of the gearbox.
Next, loosen the pilot hole bolt. If oil begins to flow from the hole, then its level is normal. If the oil does not flow, then its level is insufficient. In this case, loosen the bolt of the control hole, open the plastic cover of the filler hole of the gearbox and, using an angled funnel or flexible hose, pour oil into the gearbox until it flows out of the control hole. Now tightly tighten the test cap stopper, close the filler cap and wipe the oil leaks from the gearbox housing.
Pouring oil into the air filter.
To fill the air filter oil bath, unscrew the butterfly nut of the filter cover, remove the filter element from the pan, pour 100-150 engine oil into the oil pan (according to the level mark on the body of the oil bath), reinstall the filter element with sealing bands and filter cover, fasten it with a nut.
Pay special attention that DO NOT start the engine without an installed air filter, as well as with a filter without the necessary amount of oil. It will inevitably lead to accelerated wear of the device!
According to the factory standard, oil for diesel four-stroke engines with water cooling is used in the tiller engine and the air filter. When replacing with another type of lubricant, it must be borne in mind that the oil must be specific to SG, SF or higher. Choose engine oil by the SAE viscosity-temperature characteristic. Depending on the ambient temperature, it is allowed to use 5W-30, 10W-30, 15W-40 engine oil or oils with a broader temperature range. To determine the most appropriate type of oil, see the figure below.
To reduce the wear of mechanical gear parts and prevent scuffing on the surfaces of friction, transmission oils TAP-15, TAD-17 or similar in their properties are poured into the gearbox, for example, oils of the TM series according to GOST 17479.2–85. In the case of operation of the tiller in the cold season, it is necessary to apply winter or all-season gear oils.
Now let’s talk about the general principles and rules for changing oil for the tiller and checking its level.
For the first time, the need to change the oil for tiller occurs after five hours of its operation. This rule should not be neglected, since after assembly of the unit in its motor, various garbage, dust, and small foreign bodies inevitably remain, which, getting into the oil, can contribute to engine seizure immediately after the start of its operation. It will lead to engine failures, which can be avoided by the following rule: change the oil several times after five hours of tiller operation, and then several times after 10 hours of operation. So you can prevent the motor from failing and clean it of various impurities.
After this so-called tiller run-in, the oil should be changed as indicated in the unit instructions. As a rule, this is done in 25-50 hours after the start of operation of the device. Well, if you do not have instructions or it does not indicate how to proceed, then you can quickly determine this moment yourself. Pay attention to the colour of the oil. If the oil is black. urgently change it and try not to bring it to such a state anymore. Also, consider tiller operating conditions.
For the oil change in the tiller to occur most correctly and efficiently, the engine must be warmed up. Do not forget to prepare the container where you will drain the used oil. Now let’s look at how to perform this procedure.
Tiller with a warm engine needs a little tilt and substitute the capacity to it. Next, you need to unscrew the drain plug at the engine and drain all the oil into the container prepared for this. After that, you need to tighten the cap and pour new oil into the engine. It happens that the motor is not equipped with a drain plug. In this case, the oil must be drained through the filler hole.
Remember that regular oil change for tiller significantly extends its service life. Therefore, do not forget that the oil should be checked, mainly if your assistant works intensively and often. Regardless of whether the tiller has developed 25-35 hours per working season, the oil must be changed at least once a year. It is better to turn off the unused, barely flooded oil than to greedy, and try to work on the old oil after six months of machine downtime. Oil tends to oxidize, which leads to the inevitable deterioration of its qualities. So, with its functions, it will cope much worse.
In the process of changing the oil on the tiller, there is nothing complicated. There are several points on which you should focus your attention.
Tiller need to tilt. The measuring, drain and filler holes are always located on the left side of the motor. Old oil is drained through the drain hole, closed with a stopper.
The volume of the container for the drained liquid must be at least 2 litres. Consider: how much oil you have drained, as much should be poured. Well, the best is the oil for a tiller with a viscosity index of 10W40: synthetic or mineral. This oil and advised using manufacturers of agricultural machinery.
No one will be able to give you exact instructions: when to change the oil in the tiller. After all, you can use the unit intensively or operate it from time to time. Therefore, you only have to follow this question. Besides, if you use a tiller in the winter. pay attention to the winter oils for the engine. Let them have a considerable cost, but they can protect your unit from damage.
As you can see, there is nothing complicated in the process of changing the oil for the tiller. You should only be sure to remember that the condition and level of lubricant should be monitored; change the oil at least once a year and use quality factory liquid. We hope that our article has become useful for you, and you figured out how to replace oil for tiller. Read also our other articles on agricultural machinery and other topics.
