CAMSHAFT SYNCHRONIZER REMOVAL/INSTALLATION
REMOVAL NOTE
1. Disconnect negative battery cable.
2. Remove the camshaft position (CMP) sensor.
3. Remove synchronizer mounting bolt and synchronizer.
NOTE: The oil pump driveshaft might come out with the camshaft synchronizer. If so, retrieve the oil pump drive shaft before proceeding.
INSTALLATION NOTE
CAUTION: 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.
1. Rotate the (1) crankshaft until the No.1 cylinder is at TDC of the compression stroke and the (2) TDC mark lines up with the (3) timing mark.
CAUTION:
- A Syncro Positioning 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 SAE-5W30 engine oil prior to Installation. Failure to do so could result in gear failure upon engine start-up.
2. Install SST 303-638 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 Syncro Positioning Tool will rotate clockwise until oil pump intermediate shaft and camshaft gear engages.
3. Install the camshaft synchronizer housing assembly.
- The arrow on the Syncro Positioning Tool SST 303-638 should be 38 degrees from the centerline of the engine.
4. Install the bolt.
