Installing the piston rings
Note
The new pistons must have the same as the replaced
pistons for each cylinder
Use piston ring pliers.
Turn the piston rings so that the piston ring gaps are
positioned as illustrated.
A = Compression ring. The text on the piston ring upwards.
B = Scraper ring. Bevelling facing downwards.
C = Oil ring. Separated three ways equilaterally.
Ensure that the piston rings can rotate freely in the
piston ring grooves.
Note!
The position of the rings is critical! Incorrect
positioning can result in high oil consumption.
