Repair of a connecting rod-piston group is carried out with capital or partial engine repair, when it is necessary to change the parts of the SPG.

We check the cylinder block during a major overhaul of the engine.
The block is checked and measured to ensure reuse.

Main main gear malfunctions:
- - The bearings of the rear axle gearbox are worn, their preload is broken, the landing is weakened (uniform noise from the rear axle)
