INSPECTION
1. Measure:
S Piston-to-cylinder clearance
Measurement steps:
1st step:
S Measure the cylinder bore "C" with a cylinder
bore gauge 1 .
NOTE:
Measure the cylinder bore "C" parallel to, and at
right angles to the crankshaft. Then find the av-
erage of the measurements.

2nd step:
S Measure the piston skirt diameter "P" with a
a 15 mm (0.59 in) from the piston bottom edge.
