How to replace the cam gear on the intake side on GMC Canyon?

The procedure to replace the camshaft intake sprocket begins by removing the camshaft cover then rotating the Crankshaft clockwise until the #1 Piston arrives at top dead center (TDC) compression phase with the word delphi on the exhaust camshaft position actuator directed parallel to the Cylinder Head to cam cover mating surface. The timing mark on the intake camshaft sprocket establishes a guide for marking the adjacent section of Timing Chain. Position the camshaft holding tool (J 44221) at the rear of the camshafts before using the Timing Chain retention tool (J 44217) along with the chain holding tool (J-44217-45) to secure Timing Chain links near both engine sides by tightening wingnuts for stable gage blocks placement on the head edge. Start by removing and discarding the intake camshaft sprocket bolt before departing with the intake camshaft sprocket. To install properly position the marked Timing Chain link with the intake camshaft sprocket timing mark. Then use a 25 mm wrench on the camshaft hex and ensure the alignment pin snaps into place. Use the angle meter (J 45059) to tighten the new intake camshaft sprocket bolt until it reaches 20 n.m (15 lb ft) and an additional 100 degrees. Finish the procedure by taking out both timing tools named Timing Chain retention tool (J 44217) and chain holding tool (J-44217-45). Remove the camshaft holding tool (J 44221) then install the camshaft cover.

How to replace the Cam Gear on Bank 1 (Right Side) Intake on GMC Acadia?

The procedure to replace the Camshaft position actuator on bank 1 (Right Side) intake starts by removing the right exhaust Camshaft actuator followed by removing both the intake Camshaft position actuator bolt and right intake Camshaft position actuator. Place the intake Camshaft position actuator onto the Camshaft before loosely installing the bolt while using an open-end wrench at the Camshaft hex to stop Camshaft/engine rotation. To finish the installation reinstall the right exhaust Camshaft actuator while performing the last step of bolt tightening on the Camshaft position actuator.

How to replace the Cam Gear on the Camshaft Position Exhaust Actuator on GMC Envoy?

Start the camshaft position exhaust actuator replacement by taking out the camshaft cover. Turn the engine until delphi becomes visible on the exhaust camshaft position actuator which should be parallel with the Cylinder Head to cam cover mating surface. Use the timing indicator on the exhaust camshaft position actuator sprocket to mark a Timing Chain link which directly faces it. Use installation tool j-44217 to position its hooks through Timing Chain links by the times chain shoes at both engine sides so the gage blocks securely rest on the engine head's edges before tightening wingnuts. The installation requires removing the exhaust camshaft position actuator bolt before extracting the actuator from its mounting place. The exhaust camshaft actuator installation requires slotting it into the Timing Chain with the marked link facing the sprocket timing mark while ensuring the alignment pin engages between camshaft and actuator components. Position the actuator on the exhaust camshaft before applying an initial torque of 25 nm (18 lb ft) then finish securing it with the torque angle meter (J 36660-A) until reaching 135 degrees torque. To finish the installation replace the camshaft cover when the Timing Chain retention tool (J-44217) has been removed.
