Features of belts for Neva power tillers

The range of motor equipment is wide enough. Accordingly, the belt selected for the Neva power tiller must match the model of agricultural equipment used.

On the MB-1 and MB-2 motor-block often a V-belt transmission is installed. It is thanks to the V-belt transmission that the unit is able to move forwards and backwards. If the machine’s V-belt mechanism fails, the single-axle tractor won’t be able to function properly.

MB-1 power tillers have forward and reverse gears. MB-2 models only move forward. Because of this difference, the same belts can not be used.

The drive belt is not difficult to select if you pay attention to the following nuances:

  • Selected type should be matched to the model of equipment;
  • the dimensions of the belt;
  • the tensioning stage of the part;
  • V-belt transmission type.

V-belts designation

V-belt drive on MB motor blocks. 1 and MB. 2 performs the function of the transmission and clutch mechanism and provides:

V-belt drives on MB motor blocks. 2 and MB.1 carburetors are structurally different, which is caused by the use of different types of reducers in them

Carburetor Adjustment

The valves of the motoblock carburetor need periodic adjustment. The valve spacing is violated, which alters the timing of the valve timing and causes the engine to underperform at the advertised output. If the gap is too big, the noise appears and the valves get deformed.

As soon as any extraneous noise appears in the engine during work of the power tiller, it is necessary to adjust the carburetor. A screwdriver, wrench and blade are required for adjustment (because the valve clearance rate is 0.1 mm to 0.15 mm).

The model DM 1 carburetor is used on MB-1D power units.08.100 diaphragm type. Exterior.appearance of the carburetor DI1.08.100 is shown in the figure below:

You should always consider the size of the part. And the power to which this detail should correspond. All the parameters are written on the belt package. They are duplicated in the technical description. If you refer to the information from the motoblock manufacturer, you can find useful knowledge about which belt is recommended for which job. So, when buying, remember:

The replacement procedure itself is quite simple, so it can be done by absolutely anyone. You just need to follow the simple recommendations:

  • First, you need to turn the engine off in neutral gear;
  • Then turn off the motor;
  • Remove the tread guard;
  • Remove the worn straps (you can cut them if they are just very stretched out);
  • Install new parts. Remove the pulley from the motor, pull the belt over the gear pulley (which is left inside the mechanism) and reinstall the removed element. Be sure to check the correct placement of the belt and its integrity, because twisting and other points are simply unacceptable;
  • Put the protective cover back on.

When operating the Cascade, it’s important to adhere to simple rules and periodically check the integrity of the belt and other parts. During storage of the elements in any case they should not be bent or kept in conditions of high humidity. After performing the replacement, the owner should definitely once again inspect the pulley for burrs, scratches and other things that can quickly damage the belt. Before buying also pay attention to the quality of the product, because it must be flat, smooth and not stretched.

Belts on a single-axle Cascade tractor: dimensions, replacement with their own hands

For owners of land plots an indispensable helper is a single-axle tractor Cascade, which is manufactured at JSC Reductor-PM, located in the city of Kuskovo. Perm. Thanks to its easy operation and versatility, this machine has earned great popularity at home and abroad. As with any machinery, in addition to its strengths, there are also weaknesses, and in this article we will talk about the belts on a single-axle tractor Cascade.

Belts for Neva motoblocs: types, sizes, independent tensioning

As you know, motor blocks can be of two types. The former operates on a chain drive, while the latter operates on a belt drive. In the second case, the belt transmission is used to transfer torque from the motor to the attachments of the motoblock, and also plays the role of the clutch and transmission. We propose to consider the principles of installation of belts on a single-axle tractor Neva, as well as methods of their adjustment with your own hands.

What types of belts for a power tiller there are

To date, there are only three separate types of such mechanisms on sale. Let’s consider their names, as well as the characteristic features inherent in each of the considered instances:

  • V-belt for the Neva brand motorblock (here we are talking about the most common models, which have built-in transverse wedges, due to which continuous rotation is ensured);
  • Devices for forward motion of power tillers (in this case we mean transmission mechanisms, due to which the torque is redirected to the axle of special equipment and the movement is made forward);
  • belts for reverse (these mechanisms are used to transmit torque to the axle of the special equipment, due to which it is ensured that the motoblock moves in the reverse direction).

In each case, before buying a tensioner, you need to learn about the compliance of the selected option for the model used. It should be understood that the old worn belt is not recommended when choosing, as its dimensions and other distinctive features will not correspond to reality.

Important! When selecting this structural element, it is required to select a model that is produced directly for the special equipment used. This information is available on the manufacturer’s website or on third-party special equipment resources on the Internet.

Troubleshooting questions about the Neva MB-2 power tiller

Question: I use a Neva MB-2 single axle tractor with a subaru engine. Starts up perfectly, spark plugs are new. When you start loading. Push the lever on the knob as the engine starts to stall, does not seem to be pulling. Half of the garden ploughed normally, and the other half I can not, barely driven into the garage, itself barely pulls, no sneezing, no puffing, and measuredly so throttles.

Answer: Check how easy it is to walk from the lever on the crankcase to the carburetor throttle. With these engines it is easy. You can see everything. There’s only one pull there. When the engine’s not running, it should run very freely, without the slightest jamming. And turn back the spring. 2nd. Try to change the gasoline. From a totally different gas station, even.

Question: What is the best drive belt for the Neva MB-2 single axle tractor with a Honda engine? Is it possible to put a non-factory one. I read somewhere that they put the alternator belt from the front drive. Will it fit??

The problem with the engine is that it has not even started in the winter. What’s the size of the MB belt? 1180. Profile A.

Question: Operating a Neva MB-2c 7 single axle tractor.5 pro engine Robin Subaru ex21 (7l. с.). Bought it last year, assembled it and put it in the garage for the winter, did not start it. Yesterday I decided to try it and it didn’t even work, I poured gasoline, I had compression, spark, spark plugs, and it wouldn’t even start. I changed the gasoline to the freshest one, no effect, no compression and spark, plug is flooded. What will you like on the zero? Factory Japanese plug is bad?

Answer: do you happen to remember to put oil in the engine? Apparently you are missing the oil level, so the ignition interlock sensor is triggered. You don’t use the dipstick to fill the spark plug, but the amount of oil that’s written in the owner’s manual. The normal oil level is when it reaches the top thread of the filler neck thread. It should even drip when you unscrew the dipstick plug. single axle tractor than should stand strictly horizontally with respect to the surface.
