Position the dial bore gauge at 16 mm (5/8 in) be-
low cylinder top edge.
1. Measuring perpendicularly (90°) to piston pin axis
A. 16 mm (5/8 in)
Read the measurement on the cylinder bore gauge.
The result is the exact piston/cylinder wall clear-
ance. If clearance exceeds specified tolerance, re-
place cylinder or rebore. Refer to TECHNICAL DATA.
NOTE: Make sure the cylinder bore gauge indica-
tor is set exactly at the same position as with the
micrometer, otherwise the reading will be false.
