Note. On rings that have been in use, the marking may not be visible. Place the removed rings in the sequence of cylinder numbering and position. Install new pistons only with new piston rings.
Replacing piston rings should be carried out in the same order as for the engine «M54».
When installing rings, make sure that the mark «TOR» on the plane of the ring was turned towards the piston crown (pic. 4.88).
The axial clearance of the compression rings should be 0.020–0.060 mm (М62В44) or 0.020–0.070 mm for the first ring and 0.020–0.070 mm for the second ring (М62В46), oil scraper ring - 0.020–0.060 mm (М62В46).
The gap in the lock of the compression rings should be 0.10–0.30 mm for all engines, the oil scraper ring - 0.20–0.90 mm (М62В44) and 0.25–0.50 mm (М62В46).
