Refitting the piston rings
- Place the scraper ring spring on the piston.
- Install the scraper ring keeping the opening op-
posed to the spring junction and with the writing
"top" facing the piston crown. The chamfered side
of the oil scraper ring should always be facing the
piston crown.
- Fit the second lining with the identification letter
or the writing "top" facing the piston crown. In any
case, the step must be facing opposite the piston
crown.
- Install the first compression lining in the direction
imposed by the housing.
- It is advisable to use a fitter to facilitate the in-
stallation of the linings.
N.B.
THE TWO PISTON RINGS ARE MADE WITH A TAPERED
CYLINDRICAL CONTACT CROSS-SECTION. THIS IS TO
ACHIEVE A BETTER BEDDING.
- Misalign the lining openings at 120° as shown in the figure.
- Lubricate the components with engine oil.
- The engine uses the first compression lining with an L section.
