Cut a length of rubber hose just long enough to be pushed onto the end of the relief valve with the other end above the oil. Then operate the lift under load and observe the end of the hose. If oil is pushed out the end then the relief valve is leaking. Now why didn't I think of that????!!!!! Zane   [Reply]   [No Email]

It don't hurt 'nuttin' to remove the 6"-plate and run yer hydraulics with yer PTO. Relief valve is semi-bulletproof, look fer squirts first. Relief valve is under all the hydraulic fluid and you can't see it ......Dell   [Reply]   [Send Email]
