Removal

The connecting rod bearings are a selective fit to provide the necessary clearance. Measure clearance and select the proper connecting rod bearing.

REMOVAL
1. Disconnect battery ground cable.
2. Drain engine cooling system.
3. Drain crankcase.
4. Remove spark plugs.
5. Raise vehicle on hoist.
6. Remove oil pan.
7. Remove oil pump if required.
8. Turn crankshaft until connecting rod from which the connecting rod bearings are to be removed is at lowest point of travel.
9. Loosen retaining nuts and remove from connecting rod cap. Place retaining nuts so that they may be reinstalled on the same connecting rod bolt.
10. Tap connecting rod cap with a plastic mallet to separate from connecting rod. Carefully remove connecting rod cap from crankshaft. If lower connecting rod bearing remained on crankshaft, carefully grasp both sides and remove (oil acts as an adhesive between two precision fitted components). Use extreme care to not scratch crankshaft journal.
11. Install protective rubber caps onto connecting rod bolts to protect crankshaft journal from bolt threads. Rubber fuel line can also be used.
12. Remove upper connecting rod bearing. Push piston up enough to grasp connecting rod bearing. If connecting rod bearing remained on crankshaft, allow connecting rod bearing to remain in contact with crankshaft journal and carefully rotate to bottom side of journal. Using care, remove connecting rod bearing from crankshaft.
13. Inspect connecting rod bearings, crankshaft journal and connecting rod bearing surfaces for damage or wear.
