Cylinder Out of Round
Using a cylinder bore gauge, measure cylinder di-
ameter at 16 mm (5/8 in) from top of cylinder.
Measure diameter in piston pin axis direction then
perpendicularly (90°) to it. If the difference be-
tween readings exceed specification, cylinder
should be rebored and honed or replaced.
