  Q: How to service and repair the Cam Gear on Cadillac Catera?

  A:

  Start servicing and repairing the camshaft gear/sprocket by first removing the intake air resonator and then the intake plenum followed by removal of the Timing Belt cover. Follow up by taking off the Timing Belt and then position the Crankshaft counterclockwise at 60 degrees btdc for safety against valve and piston collisions. You should install the j 42069-1 along with the j 42069-2 from the Timing Belt alignment kit (J 42069) between camshaft drive sprockets to keep these components in position while unscrewing the camshaft drive sprocket bolt. Begin by extracting the camshaft drive sprocket bolt and afterward remove both j 42069-1 and j 42069-2 parts then proceed with removing the camshaft drive sprocket. The installation process requires precise alignment of the camshaft drive sprocket with numbered slots on the camshafts while using a new camshaft drive sprocket bolt because the old bolt cannot be reused. To tighten the bolt position the j 42069-1 or j 42069-2 against the camshaft drive sprocket and camshaft before utilizing the torque/angle meter (J 36660-A) to achieve a torque of 50 nm (37 ft. Lbs.) with additional 60 degrees followed by 15 degrees. Complete the installation by turning the Crankshaft in a clockwise direction until it reaches top dead center position then reinstall the Timing Belt followed by Timing Belt cover then intake plenum and intake air resonator in order.

  Q: How to replace the Cam Gear on Cadillac Catera?

  A:

  As the first step in camshaft drive sprocket replacement start by obtaining three tools: Timing Belt alignment kit (J 42069), torque/angle meter (J 36660-A) and the corresponding alignment tools (J 42069-1 and J 42069-2). Start the repair by removing the intake air resonator and continuing with uninstallation of both intake plenum and Timing Belt cover. Rotate the Crankshaft counterwise to a 60 degrees btdc position before Timing Belt removal so piston and valve contact can be prevented. The technician should apply the j 42069-1 and j 42069-2 tools to hold the camshaft drive sprockets stable and then proceed to remove the bolt along with both sprockets. The proper installation of the new camshaft drive sprocket requires aligning the camshaft pin to its designated numbered slot before adding a new bolt because the previous bolt cannot be reused. First secure the sprocket by using the j 42069-1 or j 42069-2 and then use the j 36660-a to apply torque of 50 nm (37 ft. Lbs.) for sixty degrees followed by additional fifteen degrees. Reinstall the Timing Belt followed by reinstallation of the Timing Belt cover along with the intake plenum and intake air resonator after you turn the Crankshaft clockwise to tdc position.
