12-3-112 OVERHAUL

35. Position tools  LRT-12-196 to LH and RH front 

inlet camshaft gears and into the  end of each 
exhaust camshaft.

CAUTION: Special tools must be fitted when 
tightening or loosening gear retaining bolts, 
otherwise damage to camshafts may occur.

36. Remove and discard bolts retaining front inlet 

camshaft gears to camshafts.

37. Remove tools  LRT-12-196 from both inlet 

camshaft gears and exhaust camshafts.

38. Remove camshaft drive gears and hub 

assemblies.

Refit

NOTE: Following front or rear timing belt 
refitment, it is possible that, after rotating the 
engine and positioning the crankshaft pulley to 
the 'SAFE' position, the timing marks on the 
rear timing gears may be misaligned. This 
misalignment is acceptable provided that the 
timing belt refitting procedure was carried out 
correctly.

1. Clean camshaft gears and hubs, crankshaft 

gear, tensioner and water pump pulleys.

CAUTION: If sintered gears have been 
subjected to prolonged oil contamination, 
they must be soaked in solvent and then 
thoroughly washed in clean solvent before 
refitting. Because of the porous 
construction of sintered material, oil 
impregnated in the gears will emerge and 
contaminate the timing belts.

2. Fit hubs to camshaft gears and fit gears to 

camshafts. 

3. Fit new camshaft gear bolts; tighten bolts 

sufficiently to allow gears to rotate without 
tipping.

4. Position timing belt to crankshaft gear.

NOTE: To prevent the timing belt from 
disengaging from the crankshaft gear when 
fitting, fit a suitable wedge between the belt and 
oil pump belt guard.

5. Fit tool LRT-12-197 into each exhaust 

camshaft in turn.

6. Using assistance, rotate each exhaust 

camshaft slightly and align timing marks on LH 
and RH rear camshaft gears.

7. Remove tool LRT-12-197.
8. Fit tools LRT-12-175 to LH and RH rear 

camshaft gears.

9. Rotate both front camshaft gears fully 

clockwise as viewed from front of engine.

10. Using fingers only, fit timing belt to gears, 

starting at the crankshaft gear and working in 
an anti-clockwise direction, keeping the belt run 
as taut as possible and turning the camshaft 
gears only a minimum amount anti-clockwise to 
fit timing belt.

CAUTION: Gears must not be rotated anti-
clockwise more than one tooth.
