Crankshaft - cast, cast iron, five-bearing. It is possible to regrind the crankshaft journals during repairs with a diameter reduction of 0.25; 0,5; 0,75; and 1 mm.
The axial movement of the crankshaft is limited by two thrust half rings. They are inserted into the cylinder block sockets on both sides of the rear main bearing, with a metal-ceramic half ring (yellow) installed on the rear side and a steel-aluminum half ring on the front side. The half rings are made in two sizes - normal and increased in thickness by 0.127 mm.
Crankshaft bearing shells - thin-walled, steel-aluminum. Upper liners 1, 2, 4 and 5 of the crankshaft bearings with a groove on the inner surface, and the lower liners - without a groove. Liners of the 3rd support (upper and lower) without groove. Connecting rod bearings (upper and lower) also without a groove.
Repair liners are made with increased thickness for crankshaft journals, reduced by 0.25; 0,5; 0.75 and 1 mm.

Flywheel - cast iron, with a pressed-on steel toothed rim for starting the engine with a starter. The flywheel is centered by the front bearing of the gearbox drive shaft, pressed into the crankshaft.
On the rear plane of the flywheel near the toothed rim there is a setting mark in the form of a conical hole. It should be located opposite the connecting rod journal of the fourth cylinder.
