Timing Drive Components: Installation

WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result.

CAUTION: If the components are to be reinstalled, they must be installed into their original locations or engine damage may occur.

NOTE: Camshaft shown installed to clarify camshaft roller follower position.

NOTE: Lubricate the camshaft roller followers with clean engine oil prior to installation.
