NOTE
During inspection of connecting rods, look for evidence of nicks or cuts along the ribbed
sides of the connecting rod. (Refer to Figure 9-25.) Do not reuse a connecting rod which is
nicked, cut, or shows any signs of damage along these ribbed surfaces. Connecting rods
damaged in this manner are subject to sudden, violent failure.
(3)
If evidence of cracks, overheating, or excessive bearing clearance is found, remove the connecting rods
and inspect in accordance with the following steps.
(4)
If conditions are satisfactory, replace the inspection covers in accordance with paragraph 9-37.
b.
Remove.
(1)
Remove the cylinder heads in accordance with paragraph 9-5.
(2)
Remove the inspection covers in accordance with paragraph 9-37.
CAUTION
Do not attempt to remove the connecting rod and piston assemblies from the cylinder block
before the ridge and carbon accumulation is removed from the cylinder liner. Failure to
remove the ridge could result in piston ring-land breakage during removal.
(3)
Remove the ridge from top of cylinder liner (27, Figure 9-24) using a sharp knife, and polish using a fine
emery cloth P-C-1 673.
