Camshaft - LH: Installation

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

NOTE: Do not allow the camshaft roller followers to move out of position when installing the camshaft.

Lubricate the camshaft and camshaft journals with clean engine oil and install the camshaft.

CAUTION: Do not remove the Timing Chain Wedge tool at any time during assembly. If the special 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 .

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

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.

NOTE: If replacement of the camshaft phaser and sprocket is necessary, transfer the scribe mark to the new camshaft phaser and sprocket.

Position the camshaft phaser and sprocket into the timing chain with the timing chain scribe marks in alignment.

Install the camshaft phaser and sprocket assembly onto the camshaft and install a new camshaft phaser and sprocket bolt finger-tight.

CAUTION: Do not allow the camshaft roller followers to move out of position when installing the camshaft.

Install the camshaft bearing caps in their original locations.
- Lubricate the camshaft bearing caps with clean engine oil.
- Position the front camshaft bearing cap.
- Position the remaining camshaft bearing caps.
- Install the bolts loosely.
Tighten the bolts in the sequence shown.
- Tighten to 10 Nm (89 lb-in).

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.

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

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

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

Tighten the camshaft phaser and sprocket bolt in 2 stages:
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Tighten an additional 90 degrees.
