Slot packing system
Refitting the piston rings
- Pistons (like cylinders) are supplied in 4 catego-
ries: M,N,O,P, must be mounted so that the refer-
ence arrow is pointing towards 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.
