Any ideas as where to start troubleshooting ? I will need a diagram if it is a pump. thank you steve [Reply]   [No Email]

No fluid or very low can burn up a hyd pump and if that happens your talking big $$ to fix/replace it. As for diagrams you need to buy a manual like the Ford I-T FO-20   [Reply]  [No Email]

The hydraulic pump is driven by a gear off of the engine, and the tachometer cable is driven off of a fitting on the hydraulic pump, so if the tach is still working then at least you know that the pump is spinning. If the tach stopped working at the same time that the hydraulics stopped working, then it may be the gears that drive the pump.   [Reply]  [No Email]

( if you have a remote there.. check to make sure you didn't kick it engaged ) if not engaged.. check to see if remotes work. if they do.. pump and relief are fine.. if oil there under the seat and no remotes, then pull cap on rear and look in for massive leaks from top. if nothing apparrent... pull top cover for a looksee. no sweat on the diagram.. your service and parts manual have them. ( what? no manual? shame on you! ) get one at the CNh parts site... free..e tc.. post back soundguy   [Reply]  [No Email]
