Camshaft Synchronizer (4.2L): Notes

WARNING: This page is about a different car, the 2003 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: DO NOT rotate crankshaft or camshaft during removal or installation of synchronizer, or fuel system will become out of time with engine and may cause engine damage.

Synchronizer Alignment Gauge must be used during the installation of the new synchronizer assembly. Failure to follow this procedure will result in the fuel system being out of time with the engine, possibly causing engine damage.

Coat camshaft synchronizer gear with engine oil prior to installation. Failure to do so, may result in gear failure.

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 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 cylinder No. 1.

Synchronizer Alignment Gauge (303-562) is required to perform this procedure. See Figure.
