How to replace the Cam Gear on Chevrolet Express 3500?

The first step for Camshaft position actuator replacement involves removal of the Oil Pump unit. The next step requires the removal of the Camshaft position (CMP) actuator solenoid valve (234). When dealing with the reluctor wheel do not apply force because 3 roll pins keep it in place and sudden movement may result in serious injuries. Unfasten the cmp actuator from the Camshaft by moving it away from the Camshaft not touching the reluctor wheel. Secure a tie strap through the center of the actuator while it spans the reluctor wheel. The en 46330 installation requires the compression of the Timing Chain tensioner guide. Position the cmp actuator correctly onto the Camshaft locating pin while the sprocket teeth fit together and the two sprocket alignment marks on the Camshaft and crankshaft match up. Attach the new cmp actuator solenoid valve (234) to the Camshaft by threading it there with light hand pressure until it fits snugly. The sprocket alignment should be checked where the cmp actuator sprocket mark faces 6 o'clock while the crankshaft sprocket mark points at 12 o'clock. First tighten the cmp actuator solenoid valve to 65 nm (48 lb ft), followed by another 90-degree rotation when using tool j 45059. After this point remove the en 46330. Finally, reinstall the Oil Pump.
