The Rocker Arm is an important part of Chevrolet Colorado vehicles specifically on the satisfactions of the valvetrain mechanism where motion is smoothly transferred from the pushrod to the intake and exhaust valves. In most cases, made out of stamped steel or aluminum, the Rocker Arm transforms the force applied by the pushrod vertically to the appropriate force needed to lift the valves. In increased RPM applications aluminum is used due to its light weighting properties while cast iron or forged carbon steel is used in diesel engines for increased strength. Chevrolet Colorado that is in the market may not have the same type of Rocker Arms as it may be either of the traditional or the roller rocker type. There's nothing like the roller rockers, for instance, those that have the usage of needle bearings when it comes to minimizing the friction, are better both for the overhead valve as well as the overhead camshaft engines. The rocker ratio which is between 1.5:1 and 1.8:1 in modern engine increases the performance of the engine through magnifying the lift from the camshaft. There are also used the upgraded fulcrum bearings for the management of stress in vehicles with high rpm Chevrolet Colorado engines.
Chevrolet Colorado Rocker Arm Parts and Q&A
- Q: How to Service and Repair the Rocker Arm Assembly on Chevrolet Colorado?A:One must remove the camshaft cover before starting the valve Rocker Arm and valve Lash Adjuster replacement. When the Crankshaft reaches the open position of the affected cylinder valve ensure the cam lobe fully compresses the spring. The en-47945 valve spring compressor (EN-47945) needs installation on the engine Cylinder Head through either one or two of the supplied fasteners placed in the coil fastener hole but one fastener works in specific areas. Perform engine rotation to reach the base circle of the cam instead of using the tool while rotating the engine since Piston contact may damage the valves. When positioning the cam on its base circle the spring stays compressed to manage the valve Rocker Arm and valve Lash Adjuster removal. Perform cleaning along with inspection of both components before you conduct lubrication on the valve Rocker Arm while adding oil to the valve Lash Adjuster. Place the valve Rocker Arm along with the valve Lash Adjuster in position before turning the engine clock-wise until the spring reaches its complete depression by the cam lobe. Take out the en-47945 from the Cylinder Head then perform the process again if needed. Finally, install the camshaft cover.
- Q: How to replace the valve rocker arm and hydraulic valve lash adjuster on Chevrolet Colorado?A:The first step for valve Rocker Arm and hydraulic valve Lash Adjuster replacement requires you to remove the camshaft cover. The Crankshaft rotation should continue until the open valve of the affected cylinder approaches full opening while the cam lobe completely presses down on the spring. You can install the valve spring compressor (EN-47945) on the engine Cylinder Head by placing one or two fasteners from the set in the coil fastener hole although some locations only need one fastener. Moving the engine after attaching the tool should be avoided because it can harm engine valves. The clock-wise engine rotation positions the cam on the base circle to enable the removal of the Lash Adjuster and rocker together. Check the valve Rocker Arm as well as the valve Lash Adjuster before cleaning and inspecting them. Before reinstallation add oil both to the valve Rocker Arm and inside the valve Lash Adjuster. Follow these steps for installation of the tool by rotating the engine counterclockwise toward the cam lobe depression of the spring once more. Use the valve spring compressor (EN-47945) again to remove it from the Cylinder Head while executing the procedure a second time if necessary. Finally, install the camshaft cover.
