groove to groove as shorn on Fig. 4 to fit it
finally under lower side of expansible ring,
setting its gap above expansible ring gap.
- Proceed likewise to fit upper steel ring,
though setting Its gap at 180°.
2 - Fitting the scraper ring: Follow usual
procedure, using special pliers.
Important: This ring has a T.O.P. reference
.ark
which must face top of piston; otherwise,
excessive oil consumption would result.
Set its gap at 180° In relation to previous
