CYLINDER BLOCK/PISTON INSPECTION

CYLINDER BLOCK DISTORTION
Check the gasket surface of the cylinder block for distortion. Use
a straightedge and thickness gauge. Take clearance readings at
several places. If any reading exceeds the service limit, replace
the cylinder block.

CYLINDER BORE
Measure the cylinder bore diameter at six places. If any one of
the measurements exceed the limit, overhaul the cylinder and
replace the piston with an oversize piston. The remaining cylin-
ders must also be rebored accordingly; otherwise, the imbal-
ance might cause excessive vibration.
