If the valve clearances are not checked and corrected,
wear could cause the valves to remain partly open,
which lowers performance, burns the valves and valve
seats and may cause serious engine damage.
6. Record the measured valve clearances on a chart
si milar to the example shown.

Valve Clearance Adjustment
Note:
•
To adjust the valve clearances the camshafts
must be removed. Follow the camshaft
removal procedure.
1. Remove the camshafts (see page 3-15).
2. Remove the tappet bucket from the cylinder head.
3. Remove the shim from the valve head.
1. Tappet bucket
2. Shim
Note:
• The shim may withdraw with the tappet
bucket.
4. Measure the original shim, using a micrometer and
select the appropriate new shim as required.
Clearance too small:
• Fit a thinner shim.
Clearance too large:
• Fit a thicker shim.
Note:
• Shims are available ranging from 1.70 mm
to 3.00 mm in increments of 0.025 mm.
5. Fit the new shim to the valve head.
6.
Lubricate the tappet bucket(s) with a 50/50 solution
of engine oil and molybdenum disulphide grease.
7.
Refit the tappet bucket.
8. Refit the camshafts (see page 3- 17).
9.
Re-check all valve clearances.
10.
Repeat the procedure if the valves require further
adjustment.
