5. Record measurements. If cylinder is tapered or
out of round beyond .002, the cylinder must be
re-bored oversize, or replaced.

Limit: .002 Max.
Cylinder Out of Round
Limit: .002 Max.
Cylinder Standard Bore Size:

PISTON INSPECTION
1. Measure piston outside diameter at apoint 5mm
upfrom thebottom of thepistonat aright angle to
the direction of the piston pin.
5mm
Piston

2. Subtract this measurement from the maximum
cylinder measurement obtained in Step 5.
Piston to Cylinder Clearance
Std: .0015-.0032I (.038- .082 mm)
Limit: .004I (.11 mm)
Piston O.D.:
Std: 3.0881-3.0891I (78.438-77.462 mm)
3. Measure piston pin bore.
