Connecting Rod and Bearings
CAUTION:
Do not clean titanium components with chlorinated solvents. Brake parts, and similar cleaning solvents, safety solvents, or refrigerant that contains chlorofluorocarbons (CFCs) should not be used. Using chlorinated solvents to clean titanium components can result in component damage, leading to stress corrosion cracking that may be undetected with normal visual inspection. Acceptable materials for cleaning titanium components include non-chlorinated solvents, alcohol, acetone, and methanol.
NOTE:
- The connecting rod and cap must be used as an assembly with no repair or modifications to either mating surface. Do not attempt to repair the rod or cap. If service is required, replace the piston, pin, and connecting rod as an assembly.
- Do not attempt to repair the bolt hole threads of the connecting rod.
- Inspect the connecting rod for the following conditions:
- Twisting (1)
- Proper fit of the connecting rod and cap mating surfaces (2)
- Nicks or gouges in the bearing bore (3)
- Damage to the bearing locating slots (4)
- Measure the connecting rod bearing bore for an out-of-round condition. Refer to Engine Mechanical Specifications (7.0L) .
- Inspect the connecting rod bearings for craters or pockets. Flattened sections on the bearing halves indicate fatigue.
- Inspect the connecting rod bearings for excessive scoring or discoloration.
- Inspect the connecting rod bearings for dirt or debris imbedded into the bearing material.
- Inspect the connecting rod bearings for improper seating, indicated by bright, polished sections of the bearing surface.
