B Do not use a piston ring installation tool when installing the oil ring side rails

Crankshaft-refitting

1 Crankshaft installation is the first major step in engine reassembly. It's assumed at this point that the engine block and crankshaft have been cleaned, inspected and repaired or reconditioned.

2 Position the engine with the bottom facing up.

3 Remove the main bearing cap bolts and lift out the caps (where applicable). Lay the caps out in the proper order.

4 If they're still in place, remove the old bearing shells from the block and the main bearing caps/ladder. Wipe the main bearing surfaces of the block and caps/ladder with a clean, lint-free cloth. They must be kept spotlessly clean.

5 Clean the back sides of the new main bearing inserts and lay the bearing half with the oil groove in each main bearing saddle in the block. Lay the other bearing half from each bearing set in the corresponding main bearing cap/ladder. Make sure the tab on each bearing insert fits into the recess in the block or cap/ ladder. Also, the oil holes in the block must line up with the oil holes in the bearing insert.

6 Clean the bearing faces in the block, then apply a thin, uniform layer of clean moly-based grease or engine assembly lube to each of the bearing surfaces. Coat the thrustwashers as well and position them either side of the No 3 bearing position with the oil grooves facing outwards.

7 Lubricate the crankshaft surfaces that contact the oil seals with moly-based grease, engine assembly lube or clean engine oil.
