Jaguar Timing Chain TSB 4.0 Ltr.pdf

8. Use the starter to turn the engine - the movement of the chain against the

tensioner blade and piton will release the mechanical tensioner.

NOTE: The revised tensioner does not have an external access

point for retracing the mechanical tensioner. If the revised

tensioner has to be removed from the engine, the camshaft cover

must first be removed to allow access to the tensioner piston and

blade to ensure that the piton is withdrawn with the tensioner

body

9. Reinstall the fuel pump relay and start the engine to repressurize the fuel

system.

10. Verify that the chain ramie is no longer present on hot or cold restarts.
