How To Adjust Valves On A Hydraulic Roller Cam?
Adjusting valves on a hydraulic roller cam requires careful attention to detail and following the proper procedure. Here’s a step-by-step guide to help you adjust the valves correctly:
- Prepare the Engine:
- Ensure the engine is turned off and cool to the touch before starting the adjustment process.
- Locate the valve covers and remove them to access the valve train components.
- Identify the Correct Valve Adjustment Sequence:
- Consult the engine manufacturer’s specifications or service manual to determine the correct valve adjustment sequence for your specific engine.
- Locate the Top Dead Center (TDC) Position:
- Rotate the engine’s crankshaft in the normal direction of rotation until the number one piston reaches the top dead center position on its compression stroke.
- Use a timing mark on the harmonic balancer or flywheel and a timing pointer to identify the TDC position accurately.
- Adjusting Valve Lash:
- Begin with the first cylinder in the valve adjustment sequence.
- Loosen the lock nut on the rocker arm stud using an appropriate wrench or socket.
- Use a feeler gauge of the recommended thickness specified by the engine manufacturer to check the valve lash (clearance) between the rocker arm and the valve stem.
- Slide the feeler gauge between the rocker arm and the valve stem. You should feel slight resistance but still be able to move the gauge back and forth.
- Adjust the valve lash by either tightening or loosening the rocker arm stud until the proper clearance is achieved. Turning the stud clockwise decreases the clearance, while counterclockwise increases it.
- Once you’ve set the correct valve lash, hold the rocker arm stud in place and tighten the lock nut securely.
- Repeat the Process:
- Move to the next cylinder in the valve adjustment sequence and repeat steps 4 and 5 until all the valves have been adjusted.
- Reinstall Valve Covers:
- Once you’ve completed the valve adjustment on all cylinders, reinstall the valve covers and ensure they are properly sealed to prevent oil leaks.
- Double-Check:
- After adjusting the valves, it’s a good practice to go through the entire valve adjustment sequence once more to confirm that all clearances are within the specified range.
