Camshaft Synchronizer - 4.2L: Installation

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: After installation, do not loosen the synchronizer bolt and rotate the synchronizer assembly. The synchronizer assembly is not adjustable. Do not loosen the synchronizer bolt after the alignment tool has been removed in order to align the CMP sensor electrical connector for any reason. If the electrical connector is not in the correct position, the synchronizer assembly must be removed, the alignment tool and the assembly reinstalled if the engine has not been rotated from TDC of the compression stroke on the No. 1 cylinder.

CAUTION: Do not turn the crankshaft or camshaft during the removal and installation procedure or the fuel system timing will be out of time with the engine and possibly cause engine damage.

CAUTION: A synchronizer alignment gauge must be used during the installation of the synchronizer assembly. Failure to follow these procedures will result in the fuel system being out of time with the engine and possibly cause engine damage.

Install the special tool on the camshaft synchronizer by rotating the tool until it engages the notch on the camshaft synchronizer housing.

NOTE: Clean and inspect the synchronizer O-ring seal. Install a new O-ring seal if necessary. Lubricate the O-ring seal with clean engine oil.

NOTE: Coat the synchronizer drive gear with clean engine oil prior to installation.

NOTE: During installation, the arrow in the synchronizer alignment tool will rotate clockwise as the gears engage.

Install the camshaft synchronizer so the arrow on the synchronizer alignment gauge is 54 degrees from the centerline of the engine.
