Motoblock "Oka": technical data

Motoblock “Oka”: technical data

Motoblock of the Kaluga plant Kadvi of the OKA series are a really popular unit for a variety of agricultural and household work. The basic design has a good hourly supply. Oka is affordable for a large number of consumers. Motoblocks of this manufacturer and this series have been used since the 1980s and are known to the consumer.

In this article, the author tried to show the maximum strengths and weaknesses of the OKA using the example of the hand-led tractor MB-1D3. The article used material from the official documentation “Operating instructions” 005.45,0100 р1. I also tried to collect as much as possible the information published on the websites that deal with the sale of agricultural devices in order to uncover the proposed topic as much as possible by a number of published videos and user ratings used.

The history of a han d-led tractor

Oka Motoblocks is the consumer name for motoblocks, which were manufactured on the basis of the MB-1 manufactured in the 1980s, a compact device with a dry weight of up to 100 kg that can perform various agricultural work. This device can be useful both on a household property and on a small arable land. It can also be useful for the mechanization of labo r-intensive processes in certain areas of large agricultural companies. Comes with a few rubber wheels and four cutters.

For a short time, this model series managed to obtain several modifications. This is mainly due to the engine, it has become more powerful. Improvements also concerned the control system. Metal poles were replaced by cables. A weak point in the gearbox has been removed. All of these changes have fully affected the MB-1D3 published in 2010.

In addition to the model above, there are previous changes in implementation, and even on the official website, the information is sometimes contradictory and contain a number of inaccuracies. In this context, when choosing a model, you should read the attached technical documentation, which is created at the highest level, carefully to make the right choice.

Technical properties of Motoblock MB-1D3

The han d-led tractor is similar to most devices in this class. It is made on a metal frame so that it is possible to hang removable devices. At the same time, his own dry weight does not exceed 100 kg. Total dimensions 1500x600x1050. Floor clearance 140 mm. Transport track adjustable 310, 570 mm.

Train force 100 kgf. Can move in 2nd gear at a speed of 9 km / h. In the first gear – 3.6 km / h. The Wenderadius is 1.1 m, the width of the treated surface is no more than 1200 mm. Plow depth up to 320 mm.

Motoblock engine

This model is equipped with an engine from its own production KADVI DM-1M1 8-strong engine from local production. It is an average of 8 kg heavier than its counterparts made abroad, but at the same time the torque is higher and among the analogues that are presented in this series of OKA engine blocks, it is the strongest.

A few words about the structure and functional principle.

Cut or not cut? That is the question!

The engine is a four-stroke single-cylinder engine, air-cooled, the service life is 5 years. According to consumer characteristics, it belongs to inexpensive economical engines. In the course of production and operation, it underwent a number of modifications, previously it had a 6.5 hp engine, which put it at a disadvantage compared to domestic competitors.

The engine is equipped with a float carburetor. Plastic filters used in the carburetor make it easier to start the engine and provide throttle response and economy. A box-type muffler was developed for this engine model, which made it possible to reduce engine noise by a third. The use of connecting rod bearings of a new type made it possible to increase the engine resource by three times.

It should be noted that the ignition system is designed to make it easier to start the engine, regardless of climatic conditions. The documentation attached to the two-wheel tractor contains a number of recommendations for the operation of the engine. Not unimportant is the fact that the engine runs on fuels from AI76 to AI93.

Factory tests have shown that the engines of this model, when properly operated, can run 2000 hours without major repairs.

Motoblock reducer

Two-speed chain reduction gear with reverse at both speeds. The advantages include the ease of maintenance and reliability of gearboxes of this type, as well as the availability of spare parts in stock. Reducers of this type can be easily modified if necessary. The weak point of this type of gearboxes are needle bearings, but on models made after 2000 this is already history.

After purchase, the device is ready for operation, the gear is filled with gear oil. It should be remembered that the first 30 hours of operation of the purchased walking tractor is a running-in period. Therefore, in order to avoid failure of the device, you should not give maximum loads.

Regarding the gearbox, it is worth mentioning that with proper care it will work for up to 3500 hours without major repairs.

coupling

Performs the function of a torque transmission mechanism from the engine to the gearbox. Like many foreign and domestic counterparts, the clutch on this model is a V-belt. This is primarily due to the operational reliability of these aggregates in order to avoid damage to the transmission and/or engine. In addition, the use of this type of clutch reduces the cost and efficiency of repairing problems that arise with the clutch. To extend the life of the drive belts, the machine must be warmed up before starting active work.

Brief overview of the OKA models

Below is a table of modifications and characteristics of the engines used in them.

Next, consider attachments, which can be divided into several groups.

Attachments on the two-wheel tractor

Unfortunately, on the manufacturer’s website there are many inaccuracies in the description of both walk-behind tractors and attachments, the site is clearly not being developed. To clarify the relevance of this or that information presented on the site, you can contact the manager. When writing the article, a lot of information was taken from the websites of companies involved in the sale of these devices.

Operation and reviews of tractor owners of walk behavior

Given the experience and a number of improvements, OKA MB-1D3 is a mining machine with low mechanization. The range of its application was described above, but separately I wanted to deal with the direct operation of the mechanism.

The purchased motoblock must be inspected before assembly. Make sure that all parts specified in the passport are available. Make sure that the guarantee coupon is correct. If everything is in order and using a detailed scheme, collect the device.

Before the first start, it is worth making sure that there is transmission and engine oil. It is recommended to replace the engine oil after the first 5 hours of operation. In the future, not so often, every 25 to 30 hours. Transmission oil replacement is performed every 100 hours of operation. Total overhauled 80 oil changes in the engine of 1000 l of gasoline. Transmission oil overhauled for the 35-speed transmission.

In one of the reviews about the walk-in tractor, the owner said that he used the old MB-1 series, which was produced at the Kaluga plant in the eighties. The body kit stayed with him. He took a modernized version of MB-1D3 and noticed that the new model has a modified gearbox, namely (replacing needle bearings with bearings according to GOST8338-75-bearing 306). I am pleasantly satisfied with the completion of the control system, now some operations can be performed without turning the walk behavior tractor itself, which was impossible on old models. Regarding the engine, a decrease in noise was noted.

A review was left in the online store where spare parts were stocked. The buyer expressed his thanks for the sale of the gearbox and was pleased with the fact that the new design gearboxes are now being sold.

In addition to positive reviews, you can often read or hear about the “cons” of the wedge head drive – belts are often torn. This is usually due to ignoring operational regulations.

One of the negative reviews was the review left about the transition plate on the imported engine. A video was applied to the recall showing the plate being torn in several places. You can supplement the above with the fact that a video was published showing an imported motor with high vibration.

A video was released detailing a number of refinements related to minor assembly imperfections such as thin wings, thick fenders and a delay when shifting into reverse.

Often there are improvements related to the weight of the unit to perform different operations. The video can be very useful to transfer the rear traction, or rather to transfer it under the right hand.

One of the videos shows the use of a segment mowing from the Saluta Walk behavior tractor. The mower is remarkably suitable for all modifications of the eye.

Reviews are extremely positive, but, as always, consumables – candle belts, rare cracks in grinders. Basically, users are talking about processing areas up to 20 acres (no more), about haymaking and cleaning in animal rooms.

Several reviews of professionals, noting a dislike of decorative knots like wings, but wearing a resistant grinding of grinding reliability, with extreme cultivation of virgin lands and clogging with the construction of land garbage.

It was a few tips to take Kadwogra which is a technology receiver of OKA series. In response, negative reviews were received about an expensive body kit and, oddly enough, about hard adhesion.

As for the model with the control system in wires, it is noted that in some regions of Russia a problem can be obtained by replacing wires. Also, a throttle cable requires constant lubrication.

One of the reviews gives a recipe for eliminating the “stalls of the engine” problem. The description of the situation is this. After overheating, in hot weather, bricks were transported a long distance, the engine was systematically overheated, closing the oil sickness rings. The episode where the fuel filter was “thrown” with oil, the engine stalled after starting. They have the bay removed by the user through a hole for a kerosene dungeon and withstand within 12 hours.

Conclusion

The Kadwi Oka motor block series in general looks like a workhorse that is not without character. It occupies a strong segment of inexpensive multifunctional units for everyday use. A wide range of consumables and the ability to fill the unit makes it come true. On the Internet you can find a sufficient number of videos with different body kit, as well as with different angles and execution.

The owners of these motoblocks are in every way modernizing the existing units, which speaks not only about the ingenuity of our employees, but also that the designer still does not want to work on the consumer properties of the units. Somewhere something is unscrewed, loosened, disappears, cracks. At the same time, the inexpensive and exceptional working characteristics are faced with a difficult choice, often in favor of this series of motoblocks. Kadwi is engaged in the production and development of other models of motoblock, but the Oka line is the most popular.
