Synchronizer

Syncro Positioning Tool:

SPECIAL SERVICE TOOL(S)

REMOVAL

CAUTION: Once the engine is aligned at TDC, do not move the crankshaft until the entire procedure is complete. Doing so will result in the fuel system being out of time with the engine, causing a possible emissions fault.

NOTE: Prior to the removal of the Camshaft Position (CMP) sensor, set the No.1 cylinder to Top Dead Center (TDC) of the compression stroke. Then note the position of the CMP sensor electrical connector. Installation procedures require that the electrical connector be located in the same position.

1. Remove the camshaft position (CMP) sensor.

2. Remove the (A) bolt and (B) clamp.

3. Remove the camshaft synchronizer.

NOTE: The oil pump driveshaft might come out with the camshaft synchronizer. If so, retrieve the oil pump driveshaft before proceeding.

INSTALLATION

CAUTION:
^ A special tool must be used during the installation of the replacement synchronizer assembly. Failure to follow this procedure will result in the fuel system being out of time with the engine, possibly causing engine damage.
^ It is very important to coat the gear on the camshaft synchronizer with Super Premium SAE-5W-30 Motor Oil XO-5W30-DSP or equivalent meeting Ford specification WSS-M2C153-G. Failure to do so could result in gear failure.

1. Install (A) Synchro Positioning Tool, aligning tabs and notches with those on the (B) camshaft synchronizer.

2. Install the camshaft synchronizer.

NOTE:
^ When installing the camshaft synchronizer into the cylinder block, make sure that the arrow on special tool is pointing toward the front of the vehicle, on a line that is parallel to the center line of the crankshaft.
^ The synchronizer will rotate slightly as the synchronizer gear engages the camshaft gear. When the synchronizer is fully installed the arrow on the special tool should point to the position of the electrical connector.

3. Position the clamp and install the bolt.
4. Remove the special tool.
5. Install the CMP sensor.
