ENGINE 3-35
CYLINDER
CYLINDER DISTORTION
Check the gasket surface of the cylinder for distortion with a
straightedge and the thickness gauge, taking a clearance read-
ing at several places as indicated. If any clearance reading
exceeds the service limit, replace the cylinder with a new one.
% Cylinder distortion
Service Limit: 0.05 mm (0.002 in)
& 09900-20803: Thickness gauge
CYLINDER BORE
Inspect the cylinder wall for any scratches, nicks or other dam-
age. Measure the cylinder bore diameter at six places.
% Cylinder bore
Service Limit: 66.090 mm (2.6020 in)
& 09900-20508: Cylinder gauge set
PISTON AND PISTON RING
PISTON DIAMETER
Measure the piston diameter with the micrometer at 18 mm
(0.71 in) from the skirt end.
If the piston diameter is less than the service limit, replace the
piston with a new one.
% Piston diameter
Service Limit: 65.880 mm (2.5937 in)
& 09900-20203: Micrometer (50 îš– 75 mm)
PISTON TO CYLINDER CLEARANCE
As a result of the aforesaid measurement, if the piston to cylin-
der clearance exceeds the following limit, overhaul the cylinder
and use an oversize piston, or replace both of the cylinder and
piston.
% Piston to cylinder clearance
Service Limit: 0.12 mm (0.0047 in)
Piston oversize: 0.5
18 mm (0.71 in)
