Piston rings - Fitting sequence
A = 1° Chromium-plated ring
B = 2° Torsional (internal tapered) ring
C = 3° Oil control ring
Important
Before tting the piston into the cylinder stagger the ring gaps
at 120°.
Pistons ringis - Clearance between grooves (mm)
Piston rings - End gaps (mm)
Place piston rings squarely into the unworn part of the lower cylinder
and measure the end gap.
Piston weight
Weigh pistons when replacing them in order to avoid unbalance.
Important
The difference in weight should not exceed 6 g.
