What kind of liquid should I fill in and how should I do it?

Lukoil-Lux and Novoil-Sint oils are suitable for lubricating the Oka car engine; for the gearbox housing - Rolst and TM5-9P transmission oils.

The Oka car manufacturer recommends the use of certain types of oils. For example, for the fuel tank - AI-91 and 95 gasoline; to fill the engine lubrication system with Lukoil-Lux, Novoil-Sint and the like. For the gearbox housing - transmission oils "Rolst", "TM5-9P" and others of the same type.

The procedure for changing the oil (if we talk specifically about the engine) should be as follows:

• Unscrew the plug from the hole called the filler hole. It is located on the cover, which, in turn, protects the cylinder head.
• As carefully as possible (the engine fluid is very hot), you should unscrew the drain plug located on the crankcase. It is important to place some kind of container under it before this and drain the liquid that has already been used.
• Then you need to unscrew the oil filter using a special wrench. What if you don’t have such a key and it’s impossible to borrow it from anyone or get it in any other way, but you can’t unscrew the filter by hand? A good option would be to try to unscrew the filter with a screwdriver, if you use it as a lever. The filter should be punched as close to the bottom as possible. Then the drain plug needs to be screwed into the crankcase.
• Fill it with new engine oil to approximately half the capacity of the oil filter. This must be done before installing the oil filter.
• After this, it is necessary to lubricate the o-ring of the new filter (that is, the oil filter) with engine oil, preferably the desired brand. Then screw the new oil filter onto the engine fitting. This must be done by hand, without the help of any tools.
• Then you should fill in as much of this oil liquid as necessary. It has already been said that the exact size of the required quantity depends on the Oka modification used. You can control how much of it has been placed in the engine using a pointer. Then you need to wrap the plug into the cap that protects the head.
• The last step is to start the engine and let it idle for a short amount of time. Ideally, the lamp indicating that the oil pressure is not normal should go out a couple of minutes after the engine has been started. Then you need to stop the engine, then check whether the oil level is sufficient. If there is not enough, add until there is as much as needed.

Description

This article will discuss the design, repair and maintenance of the OKA walk-behind tractor. Since 1991, this motorized device has been produced at the Kaluga Motor Plant under the name Motoblock MB-1.

Starting in 2011, the unit was renamed “Oka”. Its purpose is to carry out all types of agricultural work on small and medium-sized plots of land with different types of soil. Functional attachments, presented in the assortment by the manufacturer KaDvi, significantly expand the capabilities of the walk-behind tractor.

Advantages of Oka walk-behind tractors

"Oka" is a professional equipment designed for medium and small land farms. The unit, perfectly compatible with various attachments, is capable of performing a fairly wide range of work on site processing, cargo transportation and snow removal. Owners note the following advantages as the most valuable to them:

Design features include a four-stroke engine, gearbox, steering, clutch and two wheels that can be replaced with tillers for cultivating soil.

In this video you will learn the pros and cons of this walk-behind tractor:

Motoblock Oka - operating instructions

When purchasing any Oka model, the first thing you need to do is read the operating instructions for the motorized device, which contains the following sections:

1. The design of the unit (as well as the design of its components: gearbox, carburetor, etc.).
2. Assembling the Oka walk-behind tractor, according to descriptions and diagrams.
3. Technical characteristics of the selected model.
4. Instructions for starting the engine for the first time (Lifan, Honda or any other).
5. The procedure for proper running-in of the power plant.
6. Maintenance.
7. Troubleshooting the Oka walk-behind tractor.

Maintenance of Oka

Maintenance of a walk-behind tractor includes several stages:

1. Daily work before and after use.
2. Change of oil.
3. Scheduled inspection.
4. Preservation for long-term storage.

Let's consider the first point.

Before operating the Oka walk-behind tractor, you must:

• check the oil and fuel levels; only fill in high-quality working fluids;
• check the reliability of bolted connections;
• check tire pressure.

After use you must:

• thoroughly clean and wash the walk-behind tractor;
• dry in the shade;
• lubricate all components and mechanisms;
• put into storage.

No less important is the second point - “Oil change”. The first replacement is made after running in the walk-behind tractor. After every 25 operating hours, the oil level in the gearbox is checked and fluid is added if necessary. The transmission oil is changed every 50 operating hours.

Routine inspections must be carried out after the first 100, 200 and 500 engine hours; it is recommended to completely change the oils, both in the engine crankcase, gearbox, and transmission.

It is recommended to fill the engine of the Oka walk-behind tractor with the following motor oils:

We invite you to watch a short video showing how to change the oil in the gearbox of an Oka walk-behind tractor:

Malfunctions

The instructions included with the Oka walk-behind tractor contain a table that lists all possible problems, but we will focus on the most common ones:

Why the Oka walk-behind tractor does not start:

• the tank has run out of fuel;
• the oil level in the crankcase is below normal;
• the ignition system of the Oka walk-behind tractor requires adjustment or has failed;
• carburetor adjustment required;
• filters are clogged and require replacement;
• spark plugs are burnt out, smoked or wet;
• the seals have failed.

The wheels (cutters) have stopped rotating:

• the clutch cable is loose;
• it is necessary to change stretched or torn belts, this will help restore the functionality of the Oka walk-behind tractor.

The gearbox is leaking:

• the cause may be worn out cuffs of the axle shafts; they need to be replaced with new ones;
• The seals require replacement.

Extraneous noises are coming from the gearbox:

• the bearing is incorrectly installed or broken;
• broken sprockets;
• broken chain.

What to do if the speed jumps on the Oka walk-behind tractor and the gear shift does not work:

• it is necessary to inspect and, if necessary, repair the gearbox - replace broken sprockets, chains, bearings, seals;
• adjust the axle axle release mechanism;
• check gear locking.

We invite you to watch a video on how to change the bearing and replace the oil seal on the gearbox of an Oka walk-behind tractor:

Installing belts on the Oka walk-behind tractor

In order to perform the replacement, it is necessary to determine what size drive belt is required for the Oka walk-behind tractor. The following drive belts are available for sale:

For forward travel:

• A-1180 vn I GOST 1284.1-89;
• A-1213 I GOST 1284.2-89.

For reverse:

• Z(0) 1400 I;
• Z(0) 1400 ext I GOST 1284.1-89.

The belt is dismantled manually by loosening the adjusting bolt. The new belt should not sag, nor should it be under strong tension. Correct tension is when the belt bends slightly when pressed with your hand.

Lighting for Oka walk-behind tractor

Many owners of this equipment strive to modernize the device as much as possible, to further increase comfort and ergonomics when working. One of the ways to modernize is to install lights (headlights).

Making light on an Oka walk-behind tractor is not that difficult; you just need to find and connect a generator of the required power to the unit. The connection algorithm is as follows:

• a button is placed on the steering wheel;
• the generator is attached to the walk-behind tractor;
• headlights are attached to the front of the motorized device;
• through wires, a connection is made from the button to the generator and to the headlight;
• wires are insulated.

The more powerful the generator, the brighter the light will be; many people prefer to install automobile electric generators on this agricultural equipment. We invite you to watch a video on how to install the light on the Oka walk-behind tractor yourself:

We will talk about servicing a lightweight Agat walk-behind tractor with an air-cooled 4-stroke HAMMERMANN 6.5 HP engine.

Timely replacement of oil in the engine and gearbox is a necessary procedure for a walk-behind tractor. Treat this responsibly. The durability and quality of operation of units directly depends on the quality and types of oils used. Any competent salesperson in car oil stores will give you good advice - the main thing is to define the task - after all, this is not a car, but garden equipment. Please note that the mechanisms are subject to heavy loads and high temperatures (in the absence of cooling). Filling a walk-behind tractor with expensive synthetic oil, just like in your car, will simply throw money away. The additives will burn out, leaving carbon deposits on the internal components. Consider this point - the choice is yours))) You can use motor oil for 4-stroke engines of the SAE 10W-30 or SAE 15W-40 class.

First, let's look at the filler plugs - in our case there are two of them plus a drain bolt in the front lower part of the engine. The instructions included with the walk-behind tractor do not provide precise explanations. Without complicating the situation, drain the old oil by unscrewing the plug that has easy access to it. The front part of the walk-behind tractor is orange. (access to the drain bolt is difficult due to the additionally installed second trailer bracket) We drain the oil into the prepared container by tilting the walk-behind tractor - simply lift it by the steering wheel.

The oil volume in this type of engine is 0.6-0.8 liters. Remembering the words of the seller when buying a walk-behind tractor, “pour until it flows from the hole,” I agree with him. Indeed, when the casing is removed and there are no drive belts, access to the filler plug opens - in the photo on the right (black). It has been experimentally verified that exactly the specified volume is poured into it - oil is selected to the edges of the hole in the orange drain plug. If you suddenly overfill by adding more oil, all that will happen is it will burn out through the piston. The same happens when the walk-behind tractor tilts strongly and overturns. The manufacturer has installed a sensor that in such cases turns off the unit.

To drain old oil, the gearbox has a drain plug in its lower part for a flat-head screwdriver. You need to use a good power tool. The metal is soft and rolls easily - keep this fact in mind.

The filler plug in its upper part is located next to the steering mounting location. Having unscrewed it, we will not find the dipstick. How to determine the right level?

The highest level of sufficient oil in the gearbox is at the lowest point of the gear shift lever. If you fill the oil above this mark, you will see smudges - it will immediately be squeezed out. Nothing bad will happen - on almost all models of walk-behind tractors of this type I observed oil smudges in this place. Possibly poor quality of the seal is a minus. The oil volume in the gearbox is 1.1 liters. characteristics and type TAD-17I or MS-20

It is important to check all bolts and nuts for tightening torque. Seals at the mounting points of the wheel axles require special attention.

Oil leakage in this place can lead to failure of the entire gearbox when running dry. In our case, everything is in order - the mileage is exactly one year with active use even in winter on all types of wheels.

Thank you my friends for reading to the end.

Happy motor-block everyday life to you all!

What kind of oil to pour into OKA walk-behind tractor

Every owner of this equipment should know what oil to pour into the engine and gearbox of the Oka walk-behind tractor. Oil is a key factor influencing the smooth operation of the engine and gearbox under load conditions when cultivating the soil. After all, working on the ground is a difficult task, and motor vehicles operate under extreme loads.

Therefore, the oil in a walk-behind tractor needs to be changed much more often than in a car. The most correct advice on choosing oil is the recommendations of the manufacturers of the walk-behind tractor and its engine. Therefore, we turn to the Oka user manual and the operating instructions for the engines used.

Which one is better to choose?

As mentioned earlier, there are several types of oils for walk-behind tractors. It is necessary to use the liquid recommended by the manufacturer of the unit - to do this, just carefully study the labeling of the device and the Honor instructions.

In addition, each individual type of oil is divided according to its chemical composition into several types. In most cases, manufacturers try to manufacture units with the ability to use the most common types of oils - synthetic, mineral, and semi-synthetics, for example, Mannol Molibden Benzin 10W40 or SAE 10W-30.

It is worth noting that this lubricant contains a friction modifier, which creates a durable film on the inner surface of the parts. This significantly reduces the wear rate of the walk-behind tractor.

Another marking that should not be forgotten is the designation of the operating properties of oils. It also has several varieties. For example, category C is used for 4-stroke diesel engines, and category S is used for gasoline engines.

From these data a certain conclusion can be drawn. Considering the engine types, a high level of demand is directed towards all-season oils labeled 5W30 and 5W40. Among anti-corrosion oils, 10W30 and 10W40 are popular.

At temperatures above 45 degrees, oils marked 15W40, 20W40 should be used. For winter cold, it is necessary to use oil fluid 0W30, 0W40.

In cross-section, the Oka gearbox looks like this:

The body of the part is made of steel; it consists of two parts, which are fastened with three bolts and a sealing gasket. Angles are welded to each part of the body, which form the supporting frame of the device.

The transmission of the torque device of the walk-behind tractor gearbox is supplied from the left or right shaft sprocket. This part is engaged using a cracker, which moves along the axis of the shaft with a special shift knob. The recessed handle engages the sprocket, resulting in first gear being engaged. If the handle is pulled all the way, second gear will engage. In the middle position, the shift will be neutral.

Replacing the oil seal

Before changing the oil seal on the gearbox of the Oka walk-behind tractor, you need to pay attention to the manufacturer, since each part has its own technical parameters, and the replacement procedure will differ significantly.

The oil seal is one of the simplest components of a walk-behind tractor. The cost of such a device is also low. It’s easy to determine that replacement is necessary; you just need to observe the condition of the oil, namely whether it is leaking. If this is not done, then the cost of repairs will increase.

You can replace the oil seal yourself

If you decide to make the replacement yourself, then the question arises: “How to change the oil seal on the gearbox?” The first thing to do is prepare the work surface and adjust the lighting. Next, follow these steps:

1. Drain the oil from the device.
2. Prepare a piece of cloth to wipe all components.
3. Remove the wheels.
4. Remove the boot and oil seal. This can be done with a slotted screwdriver. The part needs to be pryed and simply pulled out with a rag. Such parts are not repaired, but replaced.
5. Next, wipe the shaft with a cloth, but first you need to oil it.
6. Then fill the oil back.
7. Put on the wheels.

Important! Remove the wheel from which you want to replace.

You will need: a 17mm wrench, a screwdriver, a container for draining oil, engine oil, a special wrench for removing the oil filter. This is where the oil filter is located on the engine.

Drain the oil after driving while the engine is still warm. If the engine is cold, start it and warm it up to operating temperature.

Fill with the same brand of oil that was in the engine. If you nevertheless decide to change the brand of oil, then flush the lubrication system with flushing oil or oil of the brand that will be used. To do this, after draining the old oil, fill in new oil to the lower mark of the oil level indicator. Start the engine and let it idle for 10 minutes. Drain the oil and only then change the oil filter. Now you can fill in new oil to the required level (top mark on the dipstick)

Change of oil

The oil in the gearbox of an Oka walk-behind tractor is changed once a year. TAP-115V and TAD-17I oils are suitable for these purposes. Oils are mixed in different proportions. Motor oils M-63/12G1 and M-53/10G1 are used for the engine.

The oil in the walk-behind tractor gearbox should be changed during the break-in period after twenty hours. Then after twenty-five hours you should check and top up if necessary. After fifty hours, the transmission oil should be changed; this can be done by watching a video on the Internet. Then the oil is changed every scheduled check. It’s easy to understand that a replacement needs to be made - you should pay attention to its color. If the oil is black, then you need to perform the procedure.

Such actions will improve the operation of the unit. There are three types of this liquid: synthetic, mineral and semi-synthetic. If you choose a mineral type, the engine will need to be flushed regularly.

To carry out the replacement, you must perform the following steps:

1. The car is warmed up well in order to quickly drain all the liquid.
2. Next, turn off the engine and find a container with a capacity of at least 700 milliliters.
3. We unscrew the plug and lift the unit.
4. Drain the oil into the prepared liquid.
5. We raise the car again and pour 600 milliliters of new oil into it. To perform this procedure correctly, it is necessary to measure the required amount of liquid in advance.
6. Pour oil into the engine.
7. Next, the unit should just stand for a while so that it can glass and start working. It is better if the walk-behind tractor sits without moving for a day.

What kind of oil to pour into the engine of the Oka walk-behind tractor

When purchasing a walk-behind tractor, you need to know that its long-term operation depends not so much on changing consumables, parts, tightening the appropriate nuts, but also on timely changes of oil in the walk-behind tractor.

How correctly to choose motor oil for walk-behind tractors depends on the durability and performance of the equipment. The question arises, what kind of oil to pour into the walk-behind tractor engine, how to change it or check the level.

You need to know that during the operation of the walk-behind tractor, engine oil immediately performs 4 functions:

Wide selection of oils for walk-behind tractors

During operation of an air-cooled walk-behind tractor, the lubricant burns and remains on the hot cylinder, after which a smoky emission appears. The deposition of resinous substances dramatically affects the contamination of certain parts and makes their lubrication more difficult.

It is recommended to use antioxidants with oil that cleanse the engine of dirty deposits. Correctly selected oil for a walk-behind tractor according to SAE systematization is the key to the longevity of the equipment.

When using a walk-behind tractor, you need to choose a lubricant, focusing on the climate zone.

For example, using SAE 10W30 type lubricant at a temperature of 5°C and above, its consumption will be even higher and there will be a greater possibility of engine failure. Summer lubricating waters do not need to be poured at air temperatures below 5°C. This implementation leads to difficulty starting the engine and damage to the cylinder mirror. to menu

The degree of viscosity of types of motor oil is usually systematized according to SAE (Society of Automotive Engineers).

Oil for walk-behind tractor. What kind of oil should I put in my walk-behind tractor? annotation

High-quality flushing oil MPA - 4.5

Apart from seasonal differences in lubricants, they are divided according to their composition into two types:

What else remains for our client to do is that oils are divided into lubricants for both 2-stroke and 4-stroke engines. Typically, 4-stroke air-cooling engines are installed on walk-behind tractors. Only 4-stroke oil should be poured into such engines.

Checking the oil level with a dipstick in the oil filler hole

An air-cooled engine heats up more easily during operation than a water-cooled engine under similar operating conditions. Therefore, the filling liquid must have low volatility and high thermal-oxidative stability. Also, modern oils are manufactured to be environmentally safe, i.e. the amount of smoke and toxicity of exhaust gases is controlled.

Because waste is often simply burned in boilers or steam generators, it does not have to contain components that form toxic compounds when burned. In a motor cultivator that runs on gasoline and does not even have an annotation, it is better to pour 4-stroke oil of the 5W30 or SAE30 brand.

Motoblock Oka (Oil change)

During winter, a different winter gear oil, for example 0W40, would be better. But you have to pay for such quality. There is no need to save money on this matter, because high-quality oil has the effect of minimizing wear on the engine and its durability. to menu

Units with a diesel engine are primarily used for work on large areas of land. This type of motor is capable of producing the highest traction force due to its operation at low speeds. They are designed for even more resources than gasoline ones.

Therefore, their work takes much longer without stopping. You should not often let a diesel engine run at idle speed, as this will lead to its breakdown. When you need to load the unit at full capacity for 3-4 hours. This will extend the service life of the walk-behind tractor.

Disassembly and assembly of the gearbox

Disassembling the mechanism is described above. When the procedure is completed, you need to rinse thoroughly and replace the broken parts. If replacement of the shaft seal is required, it is carried out only after removing the latter from the gearbox.

Reassemble the device in reverse order. After assembly, sealant must be applied to the surface of the housing halves. Then these halves are connected. This is done starting with the central tie bolts. Then the fastening bolts are screwed in, the procedure is performed from the middle, smoothly moving to the edge of the product.

Before making the final tightening of the bolts, you need to check whether all parts of the gearbox move smoothly. Oka walk-behind tractors are especially popular among Russian summer residents; they have a number of advantages:

• economical fuel consumption;
• low noise level of engine operation;
• compactness;
• multifunctionality.

Such devices work perfectly thanks to the equipped four-stroke engine. The unit can process not only well-groomed soils, but also virgin soil. You will not regret purchasing such a machine, since it not only works properly, but is also quite easy to repair.
