How to fix a problem mounting the valve spool on New Holland Construction Equipment?

If you are experiencing problems mounting the valve spool on your New Holland Construction Equipment, clean the valve spool and check that the screws are not too tight. Replace the spool seals if hydraulic oil is leaking through them in the spool cover. Clean the system and valve if affected by outside particles. Check the links if the control device’s links are displaced. Remove the screws for the valve protector, operate the valve spool, and tighten the screws if the centering spring in the cover is broken. If the O-rings were lubricated when replacing the valve, dismantle and remove the lubricant. Check the tightening torque if the valve spool cap bolts are not tight.
