Camshaft - check end-float
NOTE: Prior to removing the camshaft,
check end-float.
1. Position a suitable DTI to front of camshaft.
Move camshaft rearwards and zero DTI. Move
camshaft forwards and measure end-float:
End-float - maximum = 0.51 mm.
CAUTION: Camshaft end-float is
controlled by the width of Number 1
bearing in the camshaft carrier. If end-float
exceeds the above dimension, remove the
camshaft and repeat the end-float check using a
new camshaft. If end-float still exceeds the
maximum, a new cylinder head and camshaft
carrier asssembly must be fitted.
Camshaft - remove
1. Using sequence shown, loosen the 10
camshaft carrier retaining bolts 2 to 3 turns.
CAUTION: Do not fully remove bolts at this
stage.
2. Gently tap the camshaft carrier upwards to
break the sealant bond.
CAUTION: Camshaft carrier is dowel
located, do not tap it sideways.
3. Using the same sequence, continue to
progressively loosen the carrier retaining bolts
until all loading is removed from the carrier.
CAUTION: If bolts are removed completely
before loading is removed from the
camshaft carrier, the carrier may be
suddenly released and damage caused as a
result.
4. Remove retaining bolts, remove camshaft
carrier.

order and store inverted to prevent oil
loss. Do not squeeze tappet chambers
together.
Valves and springs - remove
1. Support cylinder head clear of valves, use a
hollow drift and tap each spring cap to free
collets.
2. Using tool LRT-12-034, compress valve
spring.

Cylinder head - inspection
1. Check cylinder head for warping across centre
and from corner to corner:
Maximum warp = 0.10 mm
CAUTION: Cylinder head may not be
refaced. Replace head assembly if
warping exceeds figure given.

Tappets - inspection
1. Check tappets for signs of wear, scoring and
overheating, replace as necessary.
2. Ensure oil hole in each tappet is clear.
3. Check outside diameter of each tappet:
Diameter = 34.959 to 34.975 mm.
CAUTION: Keep tappets in their fitted
order and store inverted to prevent oil
loss. Do not squeeze tappet chambers
together.
Camshaft and bearings - inspection
1. Check camshaft cams and bearing journals for
signs of scoring and excessive wear.
2. Check camshaft timing belt gear and fuel
injection pump drive belt gear drive pins for
damage and wear, replace if necessary
ensuring that split in pin faces towards centre
of camshaft.
3. Check bearing journals in cylinder head and
camshaft carrier for signs of scoring and
excessive wear.
CAUTION: Cylinder head and camshaft
carrier are machined together as an
assembly. If bearing journals in either
component are found to be damaged, complete
assembly must be replaced.
