CYLINDER DISTORTION
Check the gasketed surface of the cylinder for distortion with a
straightedge and thickness gauge, taking a clearance reading at
several places as indicated. If the largest reading at any position
of the straightedge exceeds the limit, replace the cylinder.
 Cylinder distortion
Service Limit: 0.05 mm (0.002 in)

CYLINDER BORE
Measure the cylinder bore diameter at six places. If any one of
the measurements exceeds the limit, overhaul the cylinder and
replace the piston with an oversize, or replace the cylinder.
Once the reboring is done on any one cylinder which measure-
ments is beyond the limit, the remaining cylinders must be also
rebored accordingly. Otherwise the imbalance might cause
excess vibration.
