Cylinder to piston clearance

Cylinder diameter
Measure inside diameter (Dc) with an internal bore micrometer 25 mm (0.9842
in.) below the edge (distance "A").

Piston diameter

Measure piston diameter (Dp) 7 mm (0.2755 in.) above skirt edge (distance "B").
Clearance is calculated as follows = Dc-Dp.
CLEARANCE (Dc-Dp)
0.035-0.065 mm
(0.001379-0.002561 in.)

Piston pin

The piston pin (1) must be perfectly smooth, with no signs of scoring, dents or
bluing due to overheating.
