Installation
Crankshaft1. Clean main bearing caps, bearing shell recesses and mating surfaces of cylinder block.
CAUTION: Ensure bolt holes in cylinder block and main bearing caps are clean and dry.
2. Install new upper main bearing shells, with oil holes and grooves, in cylinder block, ensuring flanged shell is installed in center position.
NOTE: If crankshaft has been reground ensure appropriate oversize bearing shells are installed.
3. Lubricate main bearing shells with engine oil and position crankshaft in cylinder block.
4. Install main bearing shells to bearing caps.
5. Lubricate main bearing shells with engine oil.
6. Install numbers 1 to 4 main bearing caps ensuring that reference marks made during dismantling are aligned, install and finger tighten main bearing cap bolts.
NOTE: Do not install side bolts at this stage.
7. Install side seals to rear main bearing cap.
CAUTION: Seals must protrude approximately 1.5 mm above bearing cap face.
8. Apply a 3 mm wide bead of Hylomar PL32 jointing compound, or equivalent to bearing cap rear mating face on cylinder block.
CAUTION: Ensure sealant does not enter bolt holes.
9. Lubricate rear main bearing shell and side seals with engine oil, carefully install rear main bearing cap assembly; install and finger tighten main bearing cap bolts.
CAUTION: Ensure that engine oil does not enter side bolt holes in bearing cap.
10. Smear new Dowty washers with engine oil and install to main bearing cap side bolts.
11. Install and finger tighten RH then LH side bolts ensuring that socket head cap bolt is installed to rear main bearing cap on RH side of cylinder block adjacent to starter motor aperture.
12. Using sequence shown, tighten bolts to:
Stage 1-Initial torque
Main bearing cap bolts-13.5 Nm
Main bearing cap side bolts-13.5 Nm
Stage 2-Final torque
Main bearing cap bolts numbers 1 to 8-72 Nm
Main bearing cap bolts numbers 9 and 10-92 Nm
Main bearing cap side bolts 11 to 20-45 Nm
13. Trim off excess material from rear main bearing cap side seals.
14. Clean seal location and running surface on crankshaft.
15. Clean seal protector tool No. LRT-12-095, or equivalent, and lubricate with engine oil.
16. Lubricate oil seal lip with engine oil.
17. Position seal protector tool No. LRT-12-095, or equivalent, to crankshaft.
18. Install seal using tool No. LRT-12-091, or equivalent.
19. Install Woodruff key to crankshaft.
20. Check crankshaft end play.
NOTE: If 0.508 mm oversize main bearings have been installed, it may be necessary to machine thrust faces of center main bearing to achieve correct end play. Ensure an equal amount of material is removed from each thrust face.
21. Install connecting rod bearings.
22. Install timing cover and gears.
23. Install flywheel or flex plate and ring gear assembly.
24. Install oil pan.
