Connecting Rod: Testing and Inspection
Cleaning And Inspection
CLEANING
CAUTION: Do not use caustic cleaning solution. Blow out all passages with compressed air.
Remove the connecting rod bearing from the connecting rod. Identify the connecting rod bearings if they are to be reused. Clean the connecting rod in
solvent, including the connecting rod bore and back of the connecting rod bearings.
INSPECTION
The connecting rods and related parts should be carefully inspected.
A shiny surface on either pin boss inside of the piston usually indicates that a connecting rod is bent.
Abnormal connecting rod bearing wear can be caused by either a bent connecting rod, a worn or damaged connecting rod journal, or a tapered
connecting rod bore.
Twisted connecting rods can create an identifiable piston skirt wear pattern, but badly twisted rods will disturb the action of the entire piston, rings,
and connecting rod assembly and may be the cause of excessive oil consumption.
CAUTION: If the connecting rod is replaced, the connecting rod cap, connecting rod bolts and connecting rod nuts must also be replaced. They are a
matched set.
Inspect the connecting rods for signs of fractures and the bearing bores for out-of-round and taper. If the bore exceeds the recommended limits and/or
if the connecting rod is fractured, the connecting rod should be replaced.
