7. Compress the valve spring ensuring that the
spring is compressed squarely to prevent
damage to components.
8. Fit the valve collets ensuring their correct
location in the spring cap and valve as the spring
compressor is released.
Always check for correct location of the valve collets
during and after assembly. If not fitted correctly, the
collets may become dislodged when the engine is
running allowing the valves to contact the pistons.
Any such valve to piston contact will cause severe
engine damage.

chain plates indicating excessive heat build-up.
2. Examine all pins for signs of rotation.
3. Check for cracking or deep scratching of the
chain piates.
4. Check for severe wear of the inner piates as
indicated in the diagram below.

For a more thorough check, proceed as follows:
1. Remove the chain from the engine.
2. Suspend the chain from a pin or hook with a
13kg weight attached at the lower end.
3. Measure across 23 links as shown in the
diagram. If the chain is within limits, the
measurement should be no longer than 147.63
mm. Measurements beyond 147.63 mm indicate
that the chain must be replaced.
