Piston: Service and Repair
Light and Heavy Pistons, Compensating For Weight Difference
Compensating For Weight Differences
The new and the old pistons can be installed in the same engine. However, the weight difference must be compensated.
Compensation is effected by installing a 14 g heavier replacement piston pin (dimensions 23 x 11 x 54).
To install the piston pin, special tool pressure piece 9500/4, order no. 000 721 950 04, must be used.
