Fitting Piston Rings
NOTE
See
Figure 3-91.
Piston rings are of two types: compression
and oil control. The two compression rings are positioned in
the two upper piston ring grooves. The dot on the second
compression ring must face upward. Ring sets are available
to fit standard and oversize pistons.

See
Figure 3-92.
Insert the new ring into the cylinder,
square it in the bore using the top of the piston and mea-
sure the ring end gap with a feeler gauge. Do not use the
ring if the end gap does not fall within the following spec-
ifications, See
Table 3-23.
NOTES
●
The same piston may be used if cylinder bore was not
changed, unless it is scuffed or grooved. If re-using pis-
ton, replace piston rings and hone the cylinder walls with
a No. 240 grit flexible hone to facilitate ring seating.
●
Piston ring sets must be properly fitted to piston and cyl-
inder.
