OVERHAUL

Big-end bearings - refit

1. Fit new bearing shells to each connecting rod.

NOTE: Big-end bearings are available in
0.254 and 0.508 mm (0.01 and 0.02 in)
oversizes.

2. Lubricate bearing shells and crankshaft

journals with engine oil.

3. Pull connecting rods on to crankshaft journals

and remove plastic tubing from bolts - if fitted.

4. Fit new bearing shells to each big-end bearing

cap.

NOTE: If crankshaft has been reground,
ensure appropriate oversize bearing shells
are fitted.

5. Lubricate bearing shells and fit bearing caps

ensuring reference marks on connecting rods
and bearing caps are aligned.

NOTE: Rib on edge of bearing cap must
face towards front of engine on RH bank
of cylinders and towards rear on LH bank

of cylinders.

6. Fit bearing cap nuts/bolts and tighten to:

Nuts - 50 Nm (37 lbf.ft).
Bolts:
Stage 1 - 20 Nm (15 lbf.ft)
Stage 2 - Further 80

°

7. Check connecting rods move freely sideways

on crankshaft. Tightness indicates insufficient
bearing clearance or misaligned connecting
rod.

8. Check clearance between connecting rods on

each crankshaft journal.
Connecting rod clearance = 0.15 to 0.36 mm
(0.006 to 0.014 in).

9. Clean oil strainer.

positioning of oil strainer when timing
cover is fitted.

CAUTION: Ensure nut is tightened to 22
Nm (16 lbf.ft) when oil pick-up pipe is fitted
to timing cover.
