Finished Pistons
All pistons are machined to the same weight in
grams, regardless of oversize to maintain piston balance. For cylinder bores which have been honed or
rebored, all service pistons include pins and are available in standard and the following oversizes: .005,
.020,
.040 inch.
Fitting Pistons
The piston and cylinder wall must be clean and dry.
Specified clearance between the piston and cylinder
wall is .0005 to .0015 inch.

the bottom
the cylinder bore in which it is to be
fitted. (An inverted piston can be used to push rings
down to insure positioning rings squarely in cylinder
bore).
(2)
Insert feeler stock in the gap. Ring gap should
be .010 to .047 inch for compression rings and .015 to

and check the oil level in the oil pan. The
pressure should be between

The oil level in the pan should never be above
