Technical characteristics correspond to those of MMZ production. It is used instead of MMZ crankshafts:
— 240-1005015
— 240-1005015-B
— 242-1005015
— 243-1005015
This type of crankshaft is installed on the MTZ-80, MTZ-82 tractor, some types of special equipment and road vehicles.
A part requires replacement when chips, cracks, and other signs of wear appear on its surface.
The crankshaft GM1215 is made of cast iron. It is a durable, wear-resistant, full support mechanism. The main necks in the production are quenched by high-frequency currents.
Design Features
- The crankshaft has four connecting rods and five main journals
- crankshaft journals 1st, 4th, 5th and 8th have counterweights; they can be removed if necessary. Due to counterweights, the wear of main bearings is reduced and the effect of centrifugal forces from unbalanced crank masses is reduced
- the crank pins have cavities closed with plugs; inside these cavities, the oil coming from the main journals through inclined channels is cleaned. In the crank pins, the oil is cleaned by the action of centrifugal forces
- The crankshaft is limited from axial movement by means of persistent half rings made of aluminum alloy. Thrust half rings are blocked from turning by protrusions inserted into the milled grooves in the bearing cover.
- mounted on the front end of the crankshaft: oil pump drive gear; distribution drive gears; V-belt drive pulley for fan, water pump and generator. A flywheel with a ring gear is mounted on the rear flange.

* The manufacturing competence of GENMOT CRANKSHAFT INDUSTRY staff allows us to manufacture products using various technologies, such as:
– casting method (own casting shop)
– casting method using ADI technology (Austempered Ductile Iron). This is an advanced method, which all leading manufacturers of automotive components of the European level are switching to. ADI injection moldings are widely used for the manufacture of wear-resistant industrial parts. Due to the hardening characteristics of the matrix, the products have an exceptional combination of wear resistance and toughness, while they have a lower weight and are easier to process
– forging method
