INSPECTION
Cylinders
Inspect cylinder walls for scratches, roughness, or ridges which
indicate excessive wear. If cylinder bore is very rough or deeply
scratched, or ridged, rebore cylinder and use over size piston.
Using a cylinder gauge, measure cylinder bore in thrust and axial
directions at two positions as shown in figure.
If any of the following conditions is noted, rebore cylinder.
1. Cylinder bore dia. exceeds limit.
2. Difference of measurements at two positions exceeds taper
limit.
3. Difference between thrust and axial measurements exceeds
out-of-round limit.
Cylinder bore dia. limit: 84.050 mm (3.3090 in.)
Taper and out-of-round limit: 0.10 mm (0.004 in.)
NOTE:
If any one of six cylinders has to be rebored, rebore all six
to the same next oversize. This is necessary for the sake
of uniformity and balance.
Pistons
Inspect piston for faults, cracks or other damages.
Damaged or faulty piston should be replaced.
Piston diameter:
As indicated in figure, piston diameter should be measured at a
position 26.5 mm (1.04 in.) from piston skirt end in the direction
perpendicular to piston pin.
