GMC Canyon Rocker Arm
It is vital component of the valvetrain in internal combustion engine in GMC Canyon Vehicles whereby it allows the coordination of the motion from the pushrod to the intake and exhaust valves. Usually made out of stamped steel or aluminum, the Rocker Arm rotates in a reciprocating motion and translates this up and down movement into the pushing force which will be needed to open the valves. In high specific rpm, aluminium is used for its low density and strength whereas cast iron or forged carbon steel is used in diesel engines. GMC Canyon has been using different types of Rocker Arms, many of them are conventional, while some others come with roller systems. Camshafts provide roller rockers that can lessen friction through needle bearings, are valuable for both overhead valve as well as the overhead camshaft engines. New GMC Canyon engines rocker ration varies from 1.5:1 to 1.8:1 this increases the camshaft lift for better performance. There are also improved fulcrum bearings that are applied in high RPM engines to ensure control of stresses and improvement of the lifetime effectiveness of the Rocker Arm system.
Each OEM GMC Canyon Rocker Arm we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
GMC Canyon Rocker Arm Parts Questions & Experts Answers
- Q: How to remove and inspect Camshaft,Lash Adjuster and Rocker Arm in inline engine on GMC Canyon?A: A special camshaft holding tool (GM# J-44221 or equivalent) is required for this procedure. After removing the cam sprocket, do not rotate the crankshaft to avoid incorrect timing and potential engine damage. Begin by removing the valve cover and the spark plugs to facilitate engine rotation. Rotate the engine until the sprocket alignment marks are aligned with a dark chain link, ensuring the nats at the rear of the camshafts are facing up. Remove the camshaft sprocket bolts and carefully detach the sprockets from the camshafts, taking care not to remove them from the chain and suspending them to prevent the chain from coming off the crankshaft sprocket. Check the camshaft caps for markings and mark them with paint if necessary before removal. Remove the camshaft cap bolts gradually until they can be taken out, then extract the camshafts, keeping them separated to avoid mixing them up. The rocker arms and lash adjusters can be lifted out if needed, and these parts should be laid out in order for reinstallation. After cleaning the camshafts, inspect each for scored journals, heat discoloration, score marks, chipped areas, pitting, uneven wear, damaged locator pin slots, and damaged threads. Measure the bearing journals with a micrometer to check for excessive wear or out-of-round conditions. Compare the camshaft lobe heights by measuring each lobe with a micrometer, recording the measurements for both intake and exhaust lobes separately; if the difference exceeds 0.005 inch, the camshaft should be replaced. If removed, soak the lash adjusters and rocker arms in clean engine oil before reinstalling them in their original locations. Coat the camshaft with clean engine oil and place it in the correct position in the cylinder head, then install the camshaft holding tool. Install all camshaft caps in their original locations and hand tighten them, then evenly tighten the caps to the specified torque, working from the center out. Remove the holding fixture, place the sprockets onto the camshafts, and tighten the bolts to the specified torque. Using a large breaker bar and socket on the crankshaft pulley bolt, rotate the crankshaft 720 degrees and re-check the sprocket and chain alignment, ensuring the darkened links align with the sprocket marks; if resistance is felt while turning the crankshaft, stop immediately to diagnose the issue. Finally, install the spark plugs and the valve cover.
