Cylinder inspection

Refer to “engine top side disassembly” .

Refer to “engine top side assembly” .

Check the gasket surface of the cylinder for distortion.

Use a straightedge and thickness gauge. Take clearance readings at several places. If any reading exceeds the service limit, replace the crankcase set.

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 cylinders must also be rebored accordingly; otherwise, the imbalance might cause excessive vibration.

Refer to “piston and piston ring inspection” (page 1d- 71).
