Removal

1. Remove ignition wires.

NOTE: This procedure will remove and install the crankshaft (6303) with the engine removed from the vehicle.

2. Remove six flywheel retaining bolts and remove flywheel (6375) from crankshaft.
3. Remove accessory drive belt (8620).
4. Remove water pump pulley (8509).
5. Remove drive belt idler pulley (8679) and drive belt tensioner (6B209) with ignition coils (12029).





6. Remove oil bypass filter (6714).





7. Remove RH and LH valve covers (6582) from cylinder heads (6049).
8. Remove crankshaft pulley bolt (6A340) and crankshaft pulley retaining washer (6378).





9. Using Crankshaft Damper Remover T58P-6316-D, pull crankshaft pulley (6312) from crankshaft.
10. Disconnect fuel charging wiring (9D930) from crankshaft position sensor (CKP sensor)(6C315) and camshaft position sensor (CMP sensor)(6B288).








11. Remove crankshaft position sensor and camshaft position sensor from engine front cover (6019).





12. Remove oil pan (6675) and oil pan gasket (6710).





13. Remove engine front cover.





14. Position crankshaft on TDC No. 1.

NOTE: This will position all pistons (6108) below top of cylinder block deck face.

15. Remove timing chains.
16. Remove camshafts (6250).





17. Remove oil pump screen cover and tube (6622) and oil pump (6600).





18. Remove crankshaft rear oil seal retainer (6335).
19. Turn crankshaft until connecting rod cap to be removed is accessible. Identify the connecting rods connecting rod caps and connecting rod bearings for cylinder position.

NOTE: Connecting rods (6200), connecting rod caps and connecting rod bearings (621 1) should be numbered to make sure they are assembled in their original positions.

20. Remove the connecting rod cap, lower and upper connecting rod bearing. Keep cap and connecting rod bearings together. Use care to prevent damage to the bearing and cylinder bore surfaces.





21. Connecting rod bolts (6214) are retained in the bolt hole with a light press fit. The connecting rod bolts have been torqued to yield at least twice and must be discarded. Use a hammer and punch to drive connecting rod bolts from connecting rod In

CAUTION: Care should be taken not to damage the cracked rod and cap joint face surfaces. Engine damage may occur.

22. Remove horizontal main bearing cap side bolts from cylinder blocks (6010).
23. Loosen crankshaft main bearing cap adjusting screws (6C360) on bearing main caps.
24. Remove bearing main cap retaining bolts. These are torque-to-yield bolts, and should not be reused.





25. Remove each main bearing cap and lower crankshaft main bearing and crankshaft thrust main bearing (6337). Keep each cap, lower crankshaft main bearings and crankshaft thrust main bearing together.

NOTE: The location of the main bearing caps and the crankshaft main bearings (6333) should be identified. When the engine is assembled, crankshaft main bearings which are to be reused should be installed in their original positions.

26. Remove crankshaft.

CAUTION: When removing the crankshaft, use care not to damage any of the bearing surfaces on the crankshaft.

27. If required, replace crankshaft main bearings, crankshaft thrust main bearing and crankshaft thrust washer (6334).
