  1. Lubricate the camshaft and camshaft journals with clean engine oil.
    2. NOTE: Do not remove the Timing Chain Locking Tool at any time during assembly. If the Timing Chain Locking Tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed. For additional information, refer to TIMING DRIVE COMPONENTS  in this service information.
    NOTE: Do not allow the roller followers to move out of position when installing the camshaft.
