Refitting the piston rings
- Pistons (like cylinders) are supplied in 4 catego-
ries: A, B, C and D, and must be fitted so that the
reference arrow faces the exhaust duct. The letter
is found at the centre of the piston.
- Fit the sealing rings with the word TOP or the
identification letter facing upwards. In any case,
the step must be facing opposite the piston crown.
- Sealing rings are manufactured with a cylinder
contact conical cross-section and piston gaps
must be offset by 120° in order to obtain a better
bedding.
- Lubricate rings with engine oil when fitting them.
CAUTION
AT EVERY NEW MOUNTING USE RETAINER RING PINS.
