PISTON TO CYLINDER WALL CLEARANCE
1. Measure piston diameter.
Piston diameter "H":
Refer to S.D.S.
Measuring point "L":
9 mm (0.35 in)
2. Check that piston clearance is within the specification.
Piston clearance:
0.023 - 0.043 mm (0.0009 - 0.0017 in)
MEASURING PISTON-TO-CYLINDER CLEARANCE
When pulling feeler gauge straight upward, measure the extracting force.
Feeler gauge thickness:
0.04 mm (0.0016 in)
Extracting force:
4.9 - 14.7 N (0.5 - 1.5 kg, 1.1 - 3.3 Ib)
SEM55C
about 180 to 220°C (356 to 428° F).
