Camshaft Synchronizer

CAMSHAFT SYNCHRONIZER REMOVAL / INSTALLATION - 3.0L








Removal
1. Disconnect the battery ground cable. See BATTERY DISCONNECT.

CAUTION:
- The No. 1 cylinder must be set on top dead center (TDC) of the compression stroke or the synchronizer assembly will not be installed correctly.
- Do not turn the crankshaft or the 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.




2. Rotate the crankshaft until the No. 1 cylinder is at top dead center (TDC) of the compression stroke and the TDC mark lines up with the timing mark.




3. Disconnect the camshaft position (CMP) sensor electrical connector.

NOTE: Prior to the removal of the camshaft position (CMP) sensor, note the position of the CMP sensor electrical connector. The installation procedure requires that the electrical connector be located in the same position.




4. Remove the screws and the CMP sensor.




5. Remove the bolt.

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

6. Remove the camshaft synchronizer.




Installation

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 causing engine damage.
- A special tool 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.
- It is very important to coat the gear on the camshaft synchronizer with engine oil prior to installation. Failure to do so could result in gear failure.




1. Install the special tool on the camshaft synchronizer by rotating the tool until it engages the notch in the camshaft synchronizer housing and the armature.

NOTE: During installation, the arrow on the special tool will rotate clockwise until the oil pump intermediate shaft and the camshaft gear engages.




2. Install the camshaft synchronizer housing assembly so the arrow on the special tool is 38° from the centerline of the engine.
3. Install the bolt.

Tightening torque: 30 N.m {30 kgf-cm, 22 ft-lbf}

4. Install the camshaft position (CMP) sensor. See CAMSHAFT POSITION (CMP) SENSOR REMOVAL / INSTALLATION - 3.0L.
