(16) Remove the cylinder block assembly (23, fig. 3-68)
up off the
piston assemblies. Observe the following:
(a) Examine the cylinder block assembly (23, fig. 3-60) for excessive wear
Cylinder bores that exhibit only slight burnishing of the bronze liners are acceptable for reuse. If the
bores exhibit galling or any other irregularity in the running surface that can be felt, the cylinder block
assembly must be discarded. If there is evidence that the bronze liners have begun to pull out of the
steel block, the cylinder block assembly must also be discarded.
(b) Examine the upper running face
of the cylinder block assembly (23). (Refer
3-69.) Circular wear patterns
or phonographing that cannot
be felt with the fingernail are normal.
