Change of oil in the gearbox of your power tiller

As a rule, the manufacturer’s manual for power tools specifies which brand and how much machine oil to use. If there are no such recommendations, the remedy is selected according to the following characteristics:

The SAE parameter indicates the viscosity grade of the substance and consists of an alphanumeric abbreviation, where the letter W indicates the possibility of use at low temperatures. The number in front indicates the viscosity at negative thermometer values, and the number after the dash at positive values. These numbers indicate how easily the fluid will be pumped through the system, and how quickly it will reach the surfaces of rubbing parts without causing dry friction.

API parameter divides lubricants into C and S categories according to their performance. Category C is for air-cooled four-stroke diesel engines and Category S for gasoline engines. Therefore, when choosing a fluid, you should always pay attention to this marking, because it has a different composition for diesel and carburetor engines.

The ACEA parameter classifies oil according to HT (viscosity at elevated temperatures)/HS (shear rate), which shows how energy efficient a grease is. The higher the value, the better it protects engine components from wear. Pour the substance with a high mPas is recommended in a tractor, mini-tractor, as well as heavy motor blocks Neva, designed for heavy loads.

The following are the types of machine grease that are best suited for your cultivator or tiller. Of course, they can be used if there are no special recommendations from the manufacturer of the equipment, and in accordance with the S and C marks. So, these are oils:

  • 5w30, 5w40 all-season, which can be poured into mototechnics at ambient temperatures at least.25 o C;
  • 10w30, 10w40 with anti-corrosion properties;
  • 15w40, 20w40 designed for pouring into the engine at a temperature of 45o C and above;
  • 0w30, 0w40 created for winter application;
  • MIL-L designed for military machines and can be applied to power tillers with diesel engines (with the code number 2104) and carburetor engines (with the code number 46152) type.

Double-labelled (SG/CD, SF/CC) can be used for all engines: it is universal and equally suitable for diesel and gasoline engines (e.g. Texas rotary cultivator). Among the variety of lubricant products, the most popular is the means produced under the brands Mobil, Castrol, ZIC, Shell Helix. In order to improve its action and quality it is added with Oil Additiv, BIZOL, Cera Tec and other additives. They can be used at ambient temperatures from.25 O C to 25 O C.

How much oil is required, how to check

Depends on the volume of the internal combustion engine. The necessary amount may be 0.6 to 1.1 liters. You can check with the factory dipstick, which has minimum and maximum marks. If the level of the lubricating component is below Min, it needs to be replaced.

Not all models are equipped with a dipstick with markings. In this case, you should be guided by the middle. if the level reaches the center, the oil is enough. Well, if there is no dipstick, you should visually inspect the filler neck to see if the product is enough to work properly. If the fluid almost reaches it, then the change is not necessary yet.

Adding oil to gasoline on a motor block

With a competent approach to the choice of lubricant and its regular replacement nodes, mechanisms and various spare parts to power tillers will not have to change often. Parts will be less susceptible to wear and are protected from corrosion.

Manufacturers warn against components with additives for two-stroke internal combustion engines, this may increase the wear of the engines. In addition, for such units, the fuel mixture should consist of gasoline and oil in the exact proportion specified by the manufacturer. The standard ratio is 4:1, where 4 is fuel. If the unit has a four-stroke engine, it usually runs on diesel, and you can not dilute this type of fuel with an oil component.

Important! Adding an oily substance to the diesel can lead to poor performance of the motor and its unsuitability later.

Variety of oils

In order to extend the life of a 4-stroke engine, you should choose the right engine oil. Its untimely replacement causes more wear and tear and shortens the operating life of the machine. How to choose the right oil, when to change it?

The engine oil contains not only the engine manual but also a data sheet.

In this manual, each manufacturer specifies what kind of oil is optimal and will extend the life of the equipment. Any lubricating fluid in an engine serves:

  • Different ambient conditions require different types of oil for lubrication and sealing;
  • Reduces the formation of carbon deposits;
  • For cooling to avoid overheating;
  • Protects from rapid wear and tear;
  • It also reduces noise;
  • prolongs the service life of the engine;
  • for its full or partial cleaning.

During the air filter process, the lubricant and its substances accumulate on the walls in the cylinder. This sludge contaminates all engine components and makes the lubrication process much more difficult.

It is for this reason that each lubricant has antioxidant components, which help to clean the walls of the cylinder from fouling, so as to prolong the operation of the motoblock.

Different weather conditions require different types of oil. All lubricants are divided by these parameters:

How much oil do you need for your power tiller motor??

Everything depends on the volume. For park and garden equipment, which has an engine up to 8 horsepower, it is enough to use 0.6 liters of grease. If your power tiller has 9-10 liters.с., 1 liter of oil is sufficient. Pour 1.1 liter of oil can be used in all other motor blocks that have 11, 13, 14, 16 horsepower. There is only a small difference in engine displacement.

Knowing what kind of engine your motor-block has, you can easily choose the type of oil and its amount. You should always read the manual of the manufacturer of the motoblock, and then there will be no difficulties with the operation of the equipment.

And you shouldn’t confuse the gearbox and the engine, because they require different amounts of lubricant. For the box will need more gear oil. from 1.5 to 2 liters on average, and sometimes 2.5 liters. The less horsepower a motor vehicle has, the less lubricant is needed for its gearbox. The largest amount of oil is poured if the power block has 16 horses (like the Profi 1900 Pro or Kentavr 2016B).

Buying lubricants for your power tiller is a responsible event, because their quality affects the safety of critical systems and assemblies of your power tiller, its performance, efficiency and service life in general. Usually all the information concerning the brand and type of oil for a power tiller is prescribed in the instruction manual. But sometimes due to loss of documents or after a major overhaul you have to pick it up yourself.

An important factor that affects the service life of your power tiller is also the timely and correct oil changes in the different systems of the machine. On how to intelligently choose oil for your motor-block and on its correct replacement we will tell you in this article.

Types of oil for your power tiller

How to fill Gear Oils and How to drain engine oil power tiller | My global activities

There are two types of engine oil for power tillers. 4-stroke and 2-stroke engines. Pour exactly the kind recommended by the manufacturer (look at the factory engine markings or read this information in the instruction manual). Both are also distinguished by two types of composition. The most common types of oil recommended by manufacturers for use in motor gears are synthetic (mineral) and semi-synthetic with a viscosity of 10W40 or 15W40. Regarding the season of use. for winter time, synthetic oils are more suitable, which have a much lower degree of thickening at lower temperatures. For summertime, however, both types of oil are mostly suitable.

A more detailed classification of oils according to basic parameters is as follows

SAE. Parameter, indicating the degree of viscosity of the lubricating fluid. Identified by an alphanumeric code, where the letter W designates the ability to use oil at different temperatures. The numbers to the left of this letter stand for the viscosity at minus temperatures and to the right of this letter stand for the viscosity at plus temperatures. This criterion is used to establish how well the lubricant can move through the system at different temperatures and to prevent chafing of parts.

API. Classify oils according to their operating properties into 2 types. Category C. for air-cooled, 4-stroke diesel engines. Category S. for gasoline engines.

ACEA. Criterion indicating energy-saving capabilities, that is, how well the oil protects the parts of the mechanism from wear and tear.

Based on these parameters and API category (gasoline or diesel single axle tractor), the most popular oils are 5w30, 5w40 (multigrade), 10w30, 10w40 (rust-proof), 15w40, 20w40 (for work in high temperatures, namely above 45°C), 0w30, 0w40 (for winter application).

Changing the oil in a power tiller engine

For the first time change oil in the tractor engine after the completion of the running-in period, which usually takes about 25-30 hours of work (depending on the model). Subsequent changes should be made not earlier than 2 times a year. in summer and winter. Even if the single axle tractor has been idle, the oil should still be checked and replaced if necessary, as it can become watered out. It is also recommended to take into account the loads to which the single axle tractor was subjected. If when visually assessing the condition of the oil you see that it has a very dark color. the change should be made immediately.

The oil change itself is simple and does not require much time. You need a container for draining and a funnel with a wide neck. Drain the oil while the engine is still hot after work. the oil drain hole is generally found either on the left or on the bottom of the engine. Have a receptacle ready to catch the oil, with the single axle tractor slightly inclined towards the container, unscrew drain plug and oil filling hole. Wait until the fluid has completely drained. If the manufacturer did not provide a drain hole for used oil. drain through the same hole as the fill. This requires tilting the single-axle tractor heavily on its side. It is better to do this procedure with two people to avoid the machine falling down or oil spilling.

Pour the same amount of oil into the single axle tractor as you have drained. Always use a dipstick to check the oil level after changing the oil. If you don’t have a dipstick, just fill the sump all the way to the plug. After changing oil it is also recommended to change spark plugs.

Some engines are especially sensitive to oil type. For example, power tillers with Subaru, Honda, BriggsStratton engines require SE grade or higher oil, but not worse than SG grade.

Changing the oil in the gearbox on your power tiller

The gearbox on your power tiller is a very busy part. it converts and transmits torque from the gears. Therefore, careful and quality lubrication of the gearbox can significantly extend the life and quality of its service.

Change the oil in the gearbox in the following sequence:

The single-axle tractor is mounted over an inspection pit or on some kind of elevation;

It is not necessary to remove the plug from the oil fill hole, which is normally located on the gearcase. Then put a prepared container for the used oil under the drain hole at the bottom;

When all the oil has drained out. the bottom drain hole is carefully closed;

Fill the gearbox with oil. Some gearboxes have a level in the form of a through-bolt, others have a dipstick on the plug. Pour the correct amount according to the oil level indicator and close the plug on the oil filling plug.

The first change is made after the running-in period. The second oil change in the gearbox is carried out approximately every 75-200 hours of operation. But everything depends on the model, so the exact timing should always be specified in the manufacturer’s instructions.

Transmission oil for the power tiller

Gearbox is filled with special gear oil and not with engine oil. Different recommendations for different models of power tillers are accordingly. For example, such types of oils as TAD-17I, TAP-15V are suitable for Neva MB-1 power tillers. For the Neva MB-2 motor-block, GOSTs recommend oils TEP-15, TM-5, SAE90 API GI-2 and so on. д. TAP-15 oil is recommended for Zubr and Kentavr power tillers.

Oil for a diesel power tiller

As well as for the choice of lubricants for other models of power tillers, in this case, you should also be guided by the instruction manual and manufacturer’s recommendations. In general, oils for diesel motoblocs are divided into the following categories

CA. for power tillers subjected to low and medium loads. Significantly reduces bearing corrosion and scaling on engine parts at high temperatures. Not suitable for use in overvoltage conditions;

CB. as well as the previous type, this oil is designed for low and medium loads. Compared to category CA, it further reduces the degree of corrosion formation;

CC. for use on medium- and heavy-duty tractors with air-cooled engines. Reduces deposits on the parts at high temperatures and reduces the risk of corrosion on the bearings;

CD- for air-cooled diesel engines that are designed to work at higher rpm.

Is it necessary to add oil to petrol for a power tiller??

Fuel for the motoblock may be clean, or it may be necessary to prepare a fuel mixture. It depends on the type of engine. For two-stroke engines, gasoline for the Moto-Block must be diluted with oil. You should clearly observe the proportions recommended by the manufacturers (often this proportion looks like 1 part oil to 4 parts gasoline). But four-stroke engines do not require this kind of mixture and fill their tanks with pure gasoline.

It is also important to note that power tillers, working on diesel, in no case need such mixtures (all diesel engines are 4-stroke). Otherwise it could end up in a serious unit failure.

Can you fill a single axle tractor with automotive engine oil?

It is not worth the risk to fill a single axle tractor with automobile oils, because automobile and power tiller engines have different lubrication principles and operating temperature regimes. Other unique qualities of a power tiller engine (design, material, power rating, etc) are also different. д.) that may be incompatible with the characteristics of automotive oils.

Having an idea of how the gearbox of a power tiller is designed, it will be much easier for the owner of an agricultural machine to lubricate and repair the mechanism.

The gearbox mechanism of the machine used in agriculture is disassembled complete with the following elements:

  • pulley and protective cover;
  • ball type bearings;
  • A bushing located in the area of the input shaft;
  • lever for adjustment and timely shifting;
  • The shift shaft and fork;
  • Screw in the oil filling plug by the pinion located in the area of the intermediate shaft;
  • the shaft block;
  • two-row steel chain;
  • washer and rubber seals;
  • input metal shaft;
  • clutch and clutch fork.

The location of each of the above elements of the motoblock gearbox in detail will show the diagram.

This design ensures trouble-free gearbox operation under almost all operating conditions. Each part of its design is important in its own way, so breakage or loss of any of them will inevitably lead to malfunction of the whole mechanism.

In each motoblock assembly, the design includes certain parts. They are slightly different in different types of gearboxes.

In parts, the mechanism consists of the following parts:

  • cover and pulley;
  • forks and shift axle;
  • of the bearings;
  • The adjusting and shifting lever is removed;
  • Sleeves on the input shaft;
  • shaft block;
  • intermediate shaft gears;
  • Washer and oil seals;
  • of the two-row chain;
  • Left and right half axle;
  • double sprocket;
  • The sprocket assembly;
  • Clutch clutches;
  • input shaft;
  • bracket and spring;
  • clutch plugs.

For a detailed look at the structure of this unit, see the diagram. The motoblock gearbox is quite complicated, but, following the diagram, you can easily cope with its disassembly and reassembly.

The following steps are performed:

  • The gearbox is completely removed;
  • The screws are unscrewed, the protection covers are removed;
  • The input shaft sleeve is removed very carefully, the fork and the lever are dismantled;
  • The primary shaft is removed together with the pinion;
  • The shaft sleeve and chain are removed;
  • The shaft assembly is removed along with the sprockets;
  • The intermediate shaft is removed together with the gears;
  • The clutch with the left and right half axles are removed.

After all these steps the gearbox can be disassembled. Once the repair is complete, it is reassembled.

A completely dry gearbox requires 2 liters of oil; with an oil change of 1.5 liters, an oil change in the gearbox of the engine block is required every 50 hours of operation. Recommended by the manufacturer of oil: transmission TAD-17I, TAP-15B or other according to GOST 23652-79, it is allowed to mix these oils in any proportions.

To the question: “Can I fill single axle tractor with automotive oil??”The specialists answer “yes, but different fluid grades can result in different consumption rates and different degrees of fouling”.
