Remove the cylinder block assembly (23, fig. 3-68) by lifting it straight up off the
piston assemblies. Observe the following:
Examine the cylinder block assembly (23, fig. 3-60) for excessive wear or damage.
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.
Examine the upper running face of the cylinder block assembly (23). (Refer to fig.
3-69.) Circular wear patterns or phonographing that cannot be felt with the fingernail are normal.
