TYPICAL
1. Indicator set to 0 (zero)
Position the dial bore gauge 50 mm (2 in) above
cylinder base, measuring perpendicularly (90°)to
piston pin axis.
Read the measurement on the cylinder bore
gauge. The result is the exact piston/cylinder wall
clearance.
PISTON/CYLINDER CLEARANCE
NEW NOMINAL
0.024 to 0.056 mm
(.001 to .002 in)
SERVICE LIMIT
0.090 mm (.004 in)
NOTE: Make sure used piston is not worn. See
PISTON MEASUREMENT above.
If clearance exceeds specified tolerance, replace
cylinder.
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.
Piston Pin
Using synthetic abrasive woven, clean piston pin
from deposits.
Inspect piston pin for scoring, cracking or other
damages.
Measure piston pin. See the following illustration
for the proper measurement position.
