Connecting Rod Bearing: Service and Repair
NOTE: This operation is performed easiest with engine out of the vehicle. However, it can be performed with the engine in the vehicle.
REMOVAL
1. Disconnect ground cable at battery and set aside.
2. Remove all six spark plugs to allow for uninhibited crankshaft rotation.
3. Raise vehicle.
4. Remove oil pan.
5. Remove oil pump if required.
6. Turn connecting rod until crankshaft from which the bearings are to be removed is at the lowest point of travel.
7. Loosen retaining nuts and remove from cap. Place retaining nuts so that they may be reinstalled on the same rod bolt.
8. Tap cap with a plastic mallet to separate from connecting rod. Carefully remove cap from crankshaft. If lower bearing remained on crankshaft,
carefully grasp both sides and remove (oil acts as an adhesive between two precision fitted components).
CAUTION: Use extreme care to not scratch crankshaft journal.
9. Install protective rubber caps onto connecting rod bolts to protect crankshaft journal from bolt threads.
NOTE: Protective caps may be made from rubber fuel line.
10. Push piston up into cylinder bore to provide clearance for removal. Remove upper connecting rod bearing.
11. Inspect connecting rod bearings, crankshaft journal and connecting rod bearing surfaces for damage or wear.
