Special Tool(s)

Special Tool(s):

Removal
1. Disconnect the camshaft position (CMP) sensor electrical connector.

2. NOTE: Prior to the removal of the 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.

Remove the 2 bolts and the CMP sensor.

3. Remove the camshaft synchronizer bolt.
4. Remove the camshaft synchronizer. Inspect the O-ring seal and install a new O-ring seal if damaged.

Installation

1. 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 camshaft position (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 must be reinstalled if the engine has not been rotated from top dead center (TDC) of the compression stroke on the No. 1 cylinder. Failure to follow this procedure will result in the fuel system being out of time with the engine, possibly causing engine damage.
- 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, 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.

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.







2. CAUTION: It is very important to coat the gear on the camshaft synchronizer with engine oil prior to installation. Failure to do so may result in gear failure.

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

Install the camshaft synchronizer housing assembly so the arrow on the special tool is 38 degrees from the centerline of the engine.







3. Install the camshaft synchronizer housing bolt.
- Tighten to 30 Nm (22 lb-ft).

4. Position the CMP sensor and install the 2 bolts.
- Tighten to 3 Nm (27 lb-in).

5. Connect the CMP sensor electrical connector.
