Camshaft Phaser and Sprocket - LH: Removal

WARNING: This page is about a different car, the 2010 Ford Pickup and 2010 Ford Cab & Chassis. 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.

Remove the LH valve cover. For additional information, refer to VALVE COVER - LH .

NOTE: Damage to the camshaft phaser and sprocket assembly will occur if mishandled or used as a lifting or leveraging device.

NOTE: Only use hand tools to remove the camshaft phaser and sprocket assembly or damage may occur to the camshaft or camshaft phaser and sprocket.

Loosen and back off the LH camshaft phaser and sprocket bolt one full turn.
Disconnect the LH Camshaft Position (CMP) sensor electrical connector.

The No. 5 cylinder camshaft 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. 5 cylinder.
Remove only the 3 camshaft roller followers shown in the illustration.

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 of 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: The crankshaft cannot be moved past the 6 o'clock position once set or engine damage may occur.

Rotate the crankshaft clockwise, as viewed from the front, positioning the crankshaft damper spoke at the 6 o'clock position and the timing mark indentation at the 7 o'clock position.

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 or damage may result.

NOTE: Engine front cover removed for clarity.

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

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 .

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

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

NOTE: Damage to the camshaft phaser and sprocket assembly will occur if mishandled or used as a lifting or leveraging device.

NOTE: Only use hand tools to remove the camshaft phaser and sprocket bolt or damage may occur to the camshaft or camshaft phaser and sprocket.

Remove the bolt and the camshaft phaser and sprocket assembly from the camshaft.
- Discard the bolt and washer.
