Cylinder bore:
1) Inspect cylinder walls for scratches, roughness,
or ridges which indicate excessive wear. If
cylinder bore is very rough or deeply scratch-
ed, or ridged, rebore cylinder and use oversize
piston.
2) Using a cylinder gauge, measure cylinder bore
in thrust and axial directions at two positions
as shown in Fig. 3-5-28.
If any of the following conditions exists,
rebore cylinder.
l
Cylinder bore dia. exceeds its limit.
l
Difference of measurements at two positions
exceeds taper limit.
l
Difference between thrust and axial measure-
ments exceeds out-of-round limit.
NOTE:
If any one of four cylinders has to be rebored,
rebore all four to the same next oversize. This is
necessary for the sake of uniformity and balance.
