Connecting Rod: Procedures
Connecting Rod Bearing Fitting
CONNECTING ROD BEARING FITTING
Inspect the connecting rod bearings for scoring (1) and (3). Check the bearings for normal wear patterns, scoring, grooving, fatigue and pitting. Replace
any bearing that shows abnormal wear.
Inspect the connecting rod journals for signs of scoring, nicks and burrs.
Misaligned or bent connecting rods can cause abnormal wear on pistons, piston rings, cylinder walls, connecting rod bearings and crankshaft connecting
rod journals. If wear patterns or damage to any of these components indicate the probability of a misaligned connecting rod, inspect it for correct rod
alignment. Replace misaligned, bent or twisted connecting rods.
1. Wipe the oil from the connecting rod journal.
2. Lubricate the upper bearing insert (2) and position in connecting rod (1). Center bearing insert in connecting rod
3. Measure at point A and point B. Measurement should be less then 0.50 mm (0.0196 in.).
