Camshaft Synchronizer: Installation
- Install synchro positioner on camshaft synchronizer by rotating tool until it engages notch in camshaft synchronizer housing and armature. See Fig 1. Tool should fit squarely in top of camshaft synchronizer assembly.
- Ensure piston No. 1 is in TDC position on compression stroke. Install oil pump drive shaft into camshaft synchronizer assembly. Lubricate camshaft synchronizer gear with engine oil. Arrow on synchro positioner will rotate clockwise until camshaft synchronizer is fully seated. Insert camshaft synchronizer assembly into engine.
- When installed, synchro positioner should point 54 degrees from centerline of engine. See Fig 2. Install and tighten camshaft synchronizer hold-down clamp bolt to specification. See TORQUE SPECIFICATIONS . Connect CMP sensor harness connector and negative battery cable. Reinstall EGR valve-to-exhaust manifold tube. See EXHAUST MANIFOLD-TO-EXHAUST GAS RECIRCULATION VALVE TUBE under EMISSION SYSTEMS & SUBSYSTEMS.
NOTE:
Synchro Positioner (303-630) must be used during installation of synchronizer assembly. Failure to follow this procedure will result in fuel system being out of time with engine, possibly causing engine damage.
NOTE:
Coat camshaft synchronizer gear with engine oil prior to installation. Failure to do so, may result in gear failure.
