Crankshaft Removal

PROCEDURE

1. Remove the oil pan, timing chain (or chains) and flywheel.

2. Remove the connecting rods with pistons.

Caution: If no repair work will be performed on the pistons and connecting rods, it is not necessary to remove the cylinder head and piston-connecting rod assembly. The pistons should only be pushed toward the combustion chambers.

3. Check the crankshaft end play (see subsection 3.1.2.9.2), then perform the following operations.

4. Remove the bolts and the rear oil seal retainer. If the guide pins are loosened, remove them and store them together with the retainer.

5. The main bearing caps must be numbered from 1 to 5, starting from the front cap (arrows). If numbers are absent, mark the caps with white paint to indicate their sequence number and orientation.

6. In the sequence opposite to that shown in the figure, loosen the main bearing cap bolts, turning each by 1/2 turn at a time. Remove the bolts.

7. Remove the caps and take out the main bearing inserts. Tape each insert to its corresponding cap.

8. Carefully remove the crankshaft, taking care not to displace the upper main bearing inserts.

9. Remove the upper main bearing inserts from the cylinder block. Tape each insert to its corresponding cap. Remove the thrust half-washers from the No. 3 bearing.
