Camshaft, rocker arms and valve lifters

Drive chain and tensioning mechanism

9. Inspect the teeth on the camshaft and crankshaft sprockets. If there is any sign of wear or damage on any sprocket, both sprockets and the drive chain should be replaced as a set.

10. Inspect the drive chain links. The degree of wear can be assessed by checking how much the chain can be bent sideways; a new chain will have only a slight lateral movement. If there is excessive lateral play in the drive chain, it must be replaced. As a precaution, the drive chain is best replaced if the engine has high mileage or if the chain has been noted to be noisy while the engine is running.



11. Inspect the chain guides and replace if necessary.

12. The condition of the tensioner can only be assessed in comparison with a new component. Replace the tensioner if there is any doubt about its condition.

Flywheel/drive disc

13. See. Section 1A, Chapter 14.

Cylinder block
