1. Remove crankshaft main bearings (6333) from cylinder blocks (6010) and bearing caps.
2. Remove connecting rod bearing (6211) from the connecting rod and caps.
3. Inspect all machined surfaces on the crankshaft for nicks, scratches, scores, etc., which could cause
premature bearing wear. Lightly stone all such surfaces.
4. CAUTION: Make sure crankshaft main bearings and bearing bores are clean. Foreign
material under the inserts will distort the crankshaft main bearing and cause a failure.
If the crankshaft main bearing journals have been refinished to a definite undersize, install the correct
undersize crankshaft main bearings.
5. Place upper main bearing inserts in position in the bores with the tang fitted in the slot provided.
6. Install lower main bearing inserts in bearing caps.
7. Carefully lower crankshaft into place.
8. Check the clearance of each crankshaft main bearing. Select fit the crankshaft main bearings for
proper clearance. Refer to
9. NOTE: Make sure that the main bearing caps are installed in their original positions and
orientation.
Apply a light coat of SAE 50 Service SG meeting Ford specification ESE-M2C39-F oil, to the journals
and bearings, and rear seal surface. Install all bearing caps.
10. Lubricate the journal with engine oil and install the thrust bearing cap with the bolts finger-tight. Pry
the crankshaft forward against the thrust surface of the upper half of the bearing. Hold the crankshaft
cap to the rear. This will align the thrust surfaces of both halves of the bearing. Retain the forward
pressure on the crankshaft. Tighten the cap bolts to 90-104 Nm (66-77 lb-ft).
