Camshaft timing belt and tensioner - inspection
1. Inspect timing belt for signs of splits at base of
teeth, fraying, oil contamination or uneven
wear. Renew timing belt if it fails inspection or
has been used for more than 48,000 miles,
80,000 km.
CAUTION: If timing belt is contaminated
with oil, cause of oil contamination must
be rectified. Timing belts must be stored
and handled with care. Always store a belt on its
edge with a bend radius greater than 30 mm. Do
not use a timing belt which has been twisted or
bent double as this can fracture the reinforcing
fibres. Do not use a belt that has been
contaminated with oil.
2. Check free length of tensioner spring:
Tensioner spring free length A = 57.5 to 58.5
mm.
3. Renew tensioner spring if free length is greater
than specified.
4. Clean timing gears, timing belt tensioner
pulley, timing belt covers and backplate.
5. Check timing belt covers for damage, renew as
necessary.
6. Clean crankshaft pulley.
Timing belt tensioner - refit
1. Attach tensioner spring to timing belt tensioner
arm.
2. Position timing belt tensioner to cylinder block,
fit but do not tighten clamp bolt.
3. Connect tensioner spring to anchorage bolt.
4. Move timing belt tensioner to minimum tension
position, tighten clamp bolt.

Timing belt - refit and adjust
1. Ensure timing marks on camshaft gears are
correctly aligned and camshaft locking tool
LRT-12-060 is fitted.
2. Ensure timing pin LRT-12-058 is inserted in
hole in flywheel.
3. Ensure timing belt tensioner is at minimum
tension position and clamp bolt is tightened
sufficiently to prevent tensioner operating.
4. Fit timing belt to crankshaft timing gear keeping
belt taut between crankshaft timing gear and
exhaust camshaft gear.
CAUTION: If original timing belt is to be
refitted, ensure direction of rotation mark
is facing correct way.
5. Slacken timing belt tensioner clamp bolt just
sufficiently to allow tensioner to operate and
tension timing belt.
CAUTION: Do not tighten clamp bolt at
this stage.
6. Fit timing belt lower cover, fit securing bolts
and tighten to 6 Nm.
7. Position crankshaft pulley on crankshaft, align
bolt holes with timing gear.
8. Position tool LRT-12-059 to crankshaft pulley,
fit and tighten 2 bolts to retain tool.
9. Fit crankshaft pulley bolt and using tool
LRT-12-059 to restrain crankshaft, tighten bolt
to 85 Nm.
10. Slacken nut retaining camshaft locking tool
LRT-12-060; remove tool.
11. Remove timing pin LRT-12-058.
12. Using tool LRT-12-059, rotate crankshaft 2
complete turns - viewed from front of engine.
13. Tighten timing belt tensioner clamp bolt to 30
Nm.
14. Remove bolts retaining tool LRT-12-059,
remove tool.
15. Fit crankshaft to timing gear bolts and tighten
to 8 Nm.
16. Fit timing belt centre cover, fit securing bolts
and tighten to 6 Nm.
17. Fit timing belt upper cover, fit securing bolts
and tighten to 6 Nm.
