How To Adjust Valves With Hydraulic Lifters?

Adjusting valve lash on hydraulic lifters is a crucial maintenance task to ensure proper engine performance and prevent issues such as noisy valves or reduced power. Here’s a step-by-step guide on how to adjust valve lash on hydraulic lifters:

1. Preparation:
   • Ensure the engine is off and cool before starting the adjustment process.
   • Familiarize yourself with the engine’s firing order and the specific valve lash specifications provided by the manufacturer for your engine model.
2. Identify the Correct Cylinder:
   • Locate the firing position of the engine by referring to the engine’s firing order diagram.
   • Identify the cylinder that corresponds to the specific valve you want to adjust.
3. Position the Cylinder:
   • Rotate the engine crankshaft manually using a socket wrench or the engine’s built-in turning mechanism.
   • Position the cylinder you want to adjust at the top dead center (TDC) on the compression stroke. You can do this by aligning the timing marks on the crankshaft pulley or using a piston stop tool.
4. Loosen the Rocker Arm:
   • Locate the rocker arm on the specific valve you want to adjust.
   • Loosen the rocker arm nut or adjuster screw using an appropriate wrench or socket.
5. Adjust the Valve Lash:
   • With the rocker arm loose, you can now adjust the valve lash. The valve lash is the clearance between the rocker arm and the valve stem.
   • Use a feeler gauge to measure the existing valve lash. Insert the appropriate thickness gauge between the rocker arm and the valve stem.
   • If the clearance is too tight, meaning the feeler gauge does not fit or has excessive resistance, you need to increase the valve lash. If the clearance is too loose, meaning the feeler gauge slides in too easily, you need to decrease the valve lash.
   • To adjust the valve lash, tighten or loosen the rocker arm nut or adjuster screw accordingly. Refer to the manufacturer’s specifications for the recommended amount of adjustment to be made.
6. Recheck the Valve Lash:
   • After making the adjustment, recheck the valve lash using the feeler gauge to ensure it falls within the recommended specifications.
   • Repeat the adjustment process if necessary until the correct valve lash is achieved.
7. Repeat for Other Cylinders:
   • Proceed to the next cylinder in the firing order and repeat steps 4 to 6 for each cylinder you want to adjust.
   • Remember to rotate the crankshaft and position each cylinder at TDC on the compression stroke before adjusting its valve lash.
8. Secure the Rocker Arm:
   • Once the valve lash is properly adjusted for each cylinder, tighten the rocker arm nut or adjuster screw to the manufacturer’s recommended torque specification.
   • Double-check that the valve lash remains within the specified range after tightening.
9. Final Checks:
   • Rotate the engine crankshaft a few times to ensure smooth rotation and check for any unusual noises or resistance.
   • Start the engine and listen for any abnormal valve noises. If you hear excessive tapping or knocking, recheck the valve lash adjustment.
