Connecting rod and piston group — inspection and repair (VAZ-2108)

Clean the piston from carbon deposits and remove all deposits from the piston and connecting rod lubrication channels. Carefully inspect the parts. Cracks of any kind on the piston, piston rings, pin, connecting rod and its cover are not allowed. If there are burrs on the working surface of the liners, they are replaced with new ones.

The clearances in height between the piston rings and grooves are checked with a set of feeler gauges, installing the ring in the corresponding groove (see table 1).

In the ring lock, the gap is checked with a set of feeler gauges, inserting the rings into a gauge with a hole diameter equal to the nominal diameter of the ring with a tolerance of ±0.003 mm. For normal-sized rings, gauge A.96137 can be used.
