Camshaft - LH: Removal

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: 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.

Loosen and back off the LH camshaft sprocket bolt one full turn.

CAUTION: If servicing both camshafts, do not rotate the crankshaft. Camshaft position has been established in Step 6.

NOTE: If the camshaft lobes are not exactly positioned as shown, the crankshaft keyway will require one full additional rotation to 12 o'clock. Do not rotate the crankshaft if servicing both camshafts.

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.

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

CAUTION: The Timing Chain Wedge tool must be installed square to the timing chain and the engine block.

NOTE: Front cover removed for clarity.

Install the special tool in the LH timing chain as shown.

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: 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 phaser sprocket assembly.

CAUTION: Remove the front thrust camshaft bearing cap straight upward from the bearing towers, or the bearing cap may be damaged from sideloading.

NOTE: The camshaft bearing caps must be installed in their original locations. Record camshaft bearing cap locations.
