Gearbox is filled with special transmission oil and not with engine oil. There are different recommendations for different models of power tillers, respectively. For example, for power tillers Neva MB-1 suitable oils such as TAD-17I, TAP-15V. For the Neva MB-2 engine block GOSTs recommend oils TEP-15, TM-5, SAE90 API GI-2, etc.
Volume of transmission oil in MB Motor Sich transmission. 4,3 l. Personally I filled the gearbox of my Motor Sich motoblock with fully synthetic gear oil Castrol SYNTRANS Z LONG LIFE 75W-80 API GL-4, which had a positive impact on the clutch and transmission clarity.
How much oil should be put in gearbox?
The question about the volume of transmission fluid is very important. Before answering it you need to determine the oil level. It’s very easy to do.
Park the single axle tractor on a level surface so that its wings are parallel to it. Take a 70 cm length of wire. You use it as a dipstick. Bend it into an arch, and then insert it into the pouring hole as far as it will go. Then take it out.
The tillers. Oil change engine 178F. Viscosity classification API. The oil sensor.
Examine the wire; if it is 30 cm soaked in grease, the oil level is normal. If the oil on it is less than 30 centimeters, it will need to be added.
If the gearbox is completely dry, you will need 2 liters of transmission fluid.
Changing the oil in your power tiller: How much and what kind of oil to put in the gearbox
Processing the land for modern gardeners is no longer as big a problem as it was in the distant past. Such versatile equipment as power tillers, which greatly facilitate the life of agronomists and gardeners, is now on sale.
The Neva power tillers are one of the best machines in their line. They are reliable, durable and versatile. You’ll be able to both till the ground and tend plants, and pick up and carry crops, trash.
Here we will tell you about the reducer for the motor-block Neva, its structure, repair. This is one of the most important elements in any machine, so if you want it to last a long time without failures, you need to know all the details of its construction, as well as the causes of faults and methods of elimination.
Gearbox device on the motor-block Neva
The gearbox of the Neva motoblock is responsible for transferring the rotation coming from the motor to the wheels and attached tools. It controls the rotational speed, speed, and direction. forward or backward. In principle, the gearbox for the MB 2 and MB 1 models is not much different, so here we will look at the second variant. The gearbox is designed in such a way that on the outside of its housing there are components that are necessary to change the gears.
The gearbox lever has 5 positions. When you press it, the fork disengages the clutch. When you drop the lever, the fork resumes its original position. The single axle tractor will stall when the drive is connected to the right half axle. There’s torque coming from the sprocket. When the knob is recessed, clutching the left sprocket, the gear is downshifted. If you want a higher gear, you have to push the knob all the way out.
Gearbox failure and repair
As with any other machine, power tillers and tractors can be at fault. If the problem is in the gearbox, you need to take it apart and repair it. Breakages are often minor and you can easily fix them yourself.
You first have to thoroughly clean dirt and oil residue from this part which also needs to be drained. All parts should be inspected and checked for damage. If something is faulty, it must be replaced. Use only new parts that fit your model of Neva power tiller. Also do not forget to fill up with oil after assembly.
Some common gearbox failures:
- The spring or clips are broken. It is necessary to replace them with new ones and after that to adjust them;
- The settings in the shifting system are out of tune. You need to loosen the screws, engage the first gear, tighten the screws back;
- The shaft is leaking oil. The cause is probably a worn collar. You need to replace it with a new one. How to change the oil seals? It is enough to remove the old ones, picking them up with a screwdriver or other object, and install new ones;
- it appears to be jammed. It may be a chain breakage. It must be replaced with a new one;
- Can’t catch the gear. The fork jaw brush is worn and must be replaced.

How to change oil in a gearbox of a power tiller
Maintenance of the gearbox of motocultivator “Neva” MK200 should be performed every 250 hours of operation. It is better to change oil in a gearbox right after machinery operation, because it is easier to drain oil at this time.
- Set tiller in upright position
- Place a container with at least 2 liters under the gearbox
- Remove the breather plug, clean it from dirt
- Remove the oil drain screw, drain the oil from the gearbox
- After draining the oil, screw in the oil drain screw and gasket. Take the oil to a waste oil collection point.
- Fill in 1.15 l fresh gear oil of the correct grade and operating temperature through the breather plug
- Screw in the breather plug.
How to Change Oil in a MotoBlock Gearbox
It is recommended to service the gearbox of your “Neva” power tiller after every 100 hours of operation or every season, whichever comes first. Only use gear oil. It is recommended to fill the gearbox with gear oil.
Changing the oil in the engine of a “Neva” power block
First of all, you need to find out whether the lubricant needs to be changed? It may be that the oil level is still sufficient for the power tiller to work efficiently. If it is still necessary to change the oil place the tiller on a leveled surface and clean the surface around the plug (plug) of the dipstick for the lubricant to fill the engine. The oil level plug is located on the lower end face of the engine.
To determine the oil level after changing the oil? It is easy enough: using the dipstick (probe). To establish the oil level, wipe the dipstick dry and then, without screwing in the plug, insert it into the oil filler neck. The oil level is indicated by the oil dipstick. On a side note! The amount of lubricant in the engine should not exceed the limit mark. If there is too much oil in the reservoir, it will overflow. This will increase unnecessary consumption of lubricants, and consequently the cost of operation.
Before checking oil level, make sure the engine has cooled down. A not-so-long-operated engine or gearbox will give wrong parameters about the amount of oil, and the level will be much higher than it really is. When the components have cooled down you can measure the level accurately.
What oil to fill in a gearbox of a power tiller?
Agricultural machinery is even more demanding than passenger cars in recent years. It is connected with high loads and severe service conditions. Due to ignorance or lack of experience many users have a question what oil to fill in a gearbox of crawler tractor for its normal and long-term work.
The tillers. Oil change.
Oil for Moto-Block: change in different systems, selection of the right oil
Is it possible to fill a single axle tractor with motor oil??
Buying lubricants for a power tiller is a responsible event, because their quality affects the safety of critical systems and assemblies of the power tiller, its serviceability, performance and service life in general. All information on the brand and type of oil for your power tiller is usually written in the owner’s manual. But sometimes due to loss of documents or after major repairs you have to pick it up yourself.
An important factor which affects the service life of your power tiller is also the timely and correct oil changes in different systems of the machine. We will tell you how to choose the right oil for your power tiller and how to change it correctly in this article.
Types of oil for your power tiller
There are 2 types of engine oils for power tillers. for 4-stroke and 2-stroke engines. Change the oil type recommended by the manufacturer (have a look at the type designation on the engine or read the manufacturer’s instructions). Both of these types are also differentiated by two types of composition. The most common types of oil recommended by manufacturers for use in motor blocks are synthetic (mineral) and semi-synthetic with a viscosity of 10W40 or 15W40. For the season of use, synthetic oils are better suited for winter because their degree of thickening at lower temperatures is much lower. For summertime, on the other hand, both types are mainly suitable.
A more detailed classification of oils by main parameters is as follows
SAE. Parameter indicating the degree of viscosity of the lubricating fluid. denoted by an alphanumeric code, where the letter W indicates the ability to use the oil at different temperatures. The numbers to the left of this letter indicate the viscosity at minus temperatures, to the right after the dash. at plus temperatures. This criterion defines how well the grease will move through the system at different temperatures and will not allow the friction of the parts.
API. Classifies oils according to their operating properties into 2 types. Category C for air-cooled four-stroke diesel engines. Category S. for gasoline engines.
ACEA. The criterion indicating the energy-saving capability, that is, the extent to which the oil will keep machine parts free from wear.
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 operation at high temperatures, namely above 45°C), 0w30, 0w40 (for winter application).
Changing the oil in your power tiller engine
The first time you change the oil in the engine of your power tiller should be at the end of the running-in period, which usually lasts about 25-30 hours (depending on the model). Subsequent oil changes should be made at the earliest twice a year, in summer and winter. Even if the single axle tractor has been idle, the oil should still be checked and changed if necessary, since it can become watery. It is also recommended to take into account the loads to which the single axle tractor was subjected. If you see that the oil is visually very dark in color you must change it immediately.
The changing process itself is not complicated and does not take much time. You need a container for draining and a funnel with a wide neck. Drain the oil before the engine cools down. The drain hole is usually either on the left or on the bottom of the engine. Have a container ready to catch the oil, tilt the single axle tractor slightly toward the container with the oil drain plug and the oil fill plug unscrewed. Wait until the fluid has completely drained. If the manufacturer has not provided a drain hole for the used oil, drain it through the same hole as the oil. To do this you will have to tilt the single axle tractor heavily on its side. This procedure is best done in pairs, to avoid dropping the machine or spilling oil.
Fill the single axle tractor with as much oil as has been drained. After that be sure to measure the level with a dipstick. If you don’t have a dipstick, just fill the crankcase all the way to the dipstick. After changing the oil it is also recommended to change the spark plugs.
Some engines are especially sensitive to oil type. For example, power tillers with Subaru, Honda, BriggsStratton engines need oil of class SE or higher, but not worse than class SG.
Changing the oil in the gearbox of your power tiller
Gearbox is a very loaded part in a motor-block. it converts and transmits torque from gears. Therefore, careful and high-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 placed over an inspection pit or on some elevated position;
first unscrew the plug from the oil fill hole, which is usually located on the gearbox. Next, place a prepared container for the used oil under the drain hole below;
when all the oil has drained out. the bottom drain hole is carefully closed
Fill the gearbox with oil. Some gear units have a level in the form of a through-bolt and others have a dipstick on the plug. Pour in the correct amount according to the oil level and screw in the plug in the filler opening.
The first oil change should be done after the running-in period. Change gearbox oil a second time every 75 to 200 hours of operation. But it all depends on the model, so the exact terms should always be clarified in the manufacturer’s instructions.
Transmission oil for power tiller
Gearbox is filled not with motor oil but with special gear oil. Different models of motor blocks have different recommendations. For example, such types of oils as TAD-17I, TAP-15V are suitable for Neva MB-1. For the Neva MB-2 power tiller, GOSTs recommend TEP-15, TM-5, SAE90 API GI-2 oils, etc. д. TAP-15 oil is recommended for Zubr and Kentavr power tillers.
Oil for your Moto-Block diesel
As with other power tool lubricant choices, it is important to follow the manufacturer’s manual and recommendations. In general, oils for diesel power tillers are divided into such categories:
CA. for power tillers with low and medium loads. Significantly reduces the degree of formation of bearing corrosion and deposits on engine parts at high temperatures. Not suitable for use in high voltage applications;
CB. like the previous oil type, this one is intended for low- and medium-duty applications. Compared to category CA it further reduces corrosion formation;
CC. for use in medium to high-stress motoblocs whose engines are air-cooled. Reduces deposits on parts at high temperatures and reduces the risk of bearing corrosion;
CD. for air-cooled diesel engines that are designed for higher revs.
Is it necessary to add oil to petrol for a power tiller??
Fuel for your power tiller may be clean, or you may have to prepare a fuel mixture. It depends on the type of engine. For two-stroke engines, gasoline for power tiller must be diluted with oil. The proportions recommended by the manufacturers should be strictly observed (often it looks like 1 part of oil to 4 parts of gasoline). This is not the case with 4-stroke engines, which require no such a mixture and are powered by pure gasoline.
It is also important to note that diesel-powered motoblocs in no way need such mixtures (all diesel engines are 4-stroke). Otherwise, it could end up in a serious machine breakdown.
Can you pour car engine oil into a single axle tractor?
It is not worth the risk to fill a single axle tractor with automobile oils, because automobile and motor-block engines have different principles of lubrication and temperature conditions. The engines for power tillers and tractors have many other unique qualities (design, materials, power output, etc.), but the engines for 4-strokes do not have the same properties as 4-cycle engines. д.), which may be incompatible with the characteristics of automotive oils.
Changing the oil in your power tiller
To change this consumable material in the Salyut 5 power tiller you can do it yourself, no need to call a specialist. Consider in more detail how to perform this procedure:
- first the mechanism should be warmed up so that the grease is less dense and can be easily drained off
- after that the unit must be shut down and the fluid in the gearbox must be systematically replaced;
- Next you need to prepare a suitable transmission fluid, as well as a packing suitable for the unit;
- Next, it is necessary to unscrew the oil plug and drain all the oil present in the mechanism;
- if necessary, a flush can be used to remove all impurities and dirt from the unit;
- then pour a new composition, and subject to mounting the packing (it is required to perform in accordance with the technology, to maintain sealing inside the unit).
After servicing, you should run the machine without load for a period of time so that all the parts can run in with the new grease.
Important! If a flushing oil is used, it should be allowed to work for a while (usually about an hour) so that all stuck-on impurities are removed.
This type of oil can withstand wide temperature fluctuations very well. So they can be successfully used all year round. When choosing this type of grease pay attention to the number in front of the letter W, it shows adaptability of the oil to low temperatures. The lower the number, the more adaptable the oil will be. If there is no letter W on the marking, such grease is suitable for summertime use.
Here, the letters on the package will indicate the type of engine. Each specific letter will indicate that the transmission fluid is suitable for a particular type of engine. The numbers indicate the engine varieties. For example, the number 4 indicates that the lubricant should be used for a four-stroke motor. The EU-value indicates the energy efficiency. The higher it is, the better the transmission fluid will be.
The largest digit on the marking will indicate that the grease can be used under extreme conditions.
GOST 17479, 1-85
These values define the viscosity level of the transmission fluid. This parameter is usually followed by numerical and alphabetic values. If it does not, it indicates that the grease is universal.
ZIC 10W40 oil is of good quality and has good reviews. It can be used in both gasoline and diesel engines.
Super T-3 85W-90
Another worthy option is Super T-3 85W-90 oil. It retains its fluidity even at quite low temperatures, with good viscosity.
Paying attention to the basic parameters, everyone will be able to choose a suitable oil in the gearbox of a motoblock, taking into account the operating conditions of the equipment, the type of engine.
