Camshaft - RH: Removal

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty and 2013 Ford F-450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The camshaft procedure must be followed exactly or damage to the valves and pistons will result.

Position the crankshaft damper spoke at the 12 o'clock position and the timing mark indentation at the 1 o'clock position.

NOTE: If the camshaft lobes are not exactly positioned as shown in the illustration, the crankshaft will require one full additional rotation to 12 o'clock.

The No. 1 cylinder camshaft exhaust lobe must be coming up on the exhaust stroke. Verify by noting the position of the 2 intake camshaft lobes and the exhaust lobe on the No. 1 cylinder.

NOTE: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into the original locations. Failure to follow these instructions may result in engine damage.

Remove only the 3 camshaft roller followers shown in the illustration from the RH cylinder head.

NOTE: The camshaft roller followers must be installed in their original locations. Record camshaft roller follower locations. Failure to follow these instructions may result in engine damage.

NOTE: Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder head must be removed. For additional information, refer to CYLINDER HEAD .

NOTE: It may be necessary to push the valve down while compressing the spring.

Using the Valve Spring Compressor, remove only the 3 designated camshaft roller followers from the previous step.

NOTE: Engine is not freewheeling. Camshaft procedure must be followed exactly or damage to valves and pistons will result.

NOTE: The Timing Chain Locking Tool must be installed square to the timing chain and the engine block.

NOTE: Front cover removed for clarity.

Install the Timing Chain Locking Tool in the RH timing chain as shown in the illustration.

NOTE: Do not remove the timing chain wedge 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 .

NOTE: The timing chain must be installed in its original position onto the camshaft sprocket using the scribed marks, or damage to valves and pistons will result.

Scribe a location mark on the timing chain and the camshaft sprocket assembly.
