CMP Synchronizer: Installation
NOTE:
If the replacement synchronizer assembly housing does not contain a plastic locator cover tool, a special service tool such as Syncro Positioning Tool (T95T-12200-A) must be obtained prior to 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.
- Align the synchronizer vane with the radial slot of the syncro positioning tool. See Fig 1. Rotate the syncro positioning tool on the synchronizer base until the tool's boss engages the base notch.
- Dip gear end into ESE-M2C123-A oil to coat gear, thrust washer and lower bearing. Insert the synchronizer assembly (with tool) into the block. The tool should be aimed approximately 75 degrees counterclockwise from the centerline of the engine. See Fig 2.
- Rotate the tool clockwise slightly to engage the oil pump intermediate shaft. Continue the downward motion, twisting the tool lightly until the synchronizer gear engages the camshaft gear. With the synchronizer flange fully seated against the block, the tool should point rearward 33 to 45 degrees counterclockwise off engine centerline.
- If camshaft position sensor electrical connector is not positioned properly, DO NOT reposition the connector by rotating the synchronizer assembly. This will result in the fuel system being out of time with the engine, possibly causing engine damage. Remove the synchronizer assembly and repeat installation procedure, beginning with step 1. Install hold-down clamp and tighten to specification. See TORQUE SPECIFICATIONS . Install CMP sensor to synchronizer and tighten to specification. Reconnect wiring to CMP sensor. Connect negative battery cable.
- Remove Syncro Positioning Tool. Install CMP sensor and retaining screws. Tighten screws to specification. Connect fuel charging wiring to camshaft position sensor stator assembly. Connect battery ground cable.
