How To Adjust Hydraulic Valve Lifters?
Adjusting hydraulic valve lifters is a crucial maintenance task to ensure proper engine performance and prevent issues like valve train noise and reduced power. Here’s a step-by-step guide on how to adjust hydraulic valve lifters:
- Prepare the Engine:
- Before starting the adjustment process, make sure the engine is turned off and cool to the touch.
- Remove any components necessary to access the valve covers, such as the air cleaner assembly or spark plug wires.
- 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.
- Some engines have a firing order that dictates the sequence, while others have specific instructions based on cylinder numbering.
- 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 (TDC) position on its compression stroke.
- Use a timing mark on the harmonic balancer or flywheel and a timing pointer to determine the TDC position accurately.
- Adjusting Valve Lifters:
- Start with the first cylinder in the valve adjustment sequence.
- Remove the valve cover to access the rocker arms and valve lifters.
- Loosen the lock nut on the rocker’s arm using an appropriate wrench or socket.
- Turn the adjusting screw or stud on the rocker’s arm clockwise to decrease the valve clearance or counterclockwise to increase it.
- Check the engine manufacturer’s specifications for the recommended valve clearance. Use a feeler gauge to measure the clearance between the rocker arm and the valve stem.
- Adjust the valve lifter until the proper clearance is achieved. You should feel slight resistance but still be able to move the feeler gauge back and forth.
- Hold the adjusting screw or 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 valve lifters 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 valve lifters, it’s advisable to go through the entire valve adjustment sequence once more to confirm that all clearances are within the specified range.
