No lift/tilt/Aux power

[B_rad]

I have an '99 863 F-Series (just shy of 2800 hrs) that I have no lift/tilt/aux power. I can lift/tilt/run aux through the motions, but will handle zero load. Forward/reverse work great...I can push my big rounds into the pen, but no lift power. Any knowledge would be greatly appreciated!!

Bobcat that is...in the event the question comes up

Working on this again. Pulling the 6673913 implement pump and wondering if anyone has any tricks? Is the side panel on the frame removed for access? Any assistance would be great appreciated!

Well, I got what Bobcat told me to order...but the stick out is way to short. Frustrated is an understatement.

I am surprised you have gotten no replies. Too bad about the part not being what you need.

Your pump is not a 6673913. There should be some numbers on the housing. I may be able to provide the correct pump if you can get me those numbers. I wouldn't mind having the serial number of your machine to verify as well.

Are you 100% certain the pump is the problem?
Now that it's already out, I would take it to a competent hydraulic shop and have them bench test it. IF it does test bad, have them take it apart, inspect it, and do a rebuild estimate.
Probably will be a lot less than a new pump, and you know it's going to fit

It's been thru Bobca. They have rebuilt the control valve, and identified this is the issue, but had no time to work on it, and would not work with a rebuilt from a 3rd party. They gave me all the info to order a rebuild, but the mechanic that was going to work on it is too far out.

Same shop has been working on this machine. The only thing that appears offb

I do know the ggiy that had it before us rode it hard and put it away wet. I blew a hose an ended up cavitating a bit. After the control valve rebuild, which had blown seals, the lift/load test no weight went great loaded it fell on its face...no lift, tilt or aux.

Good news is, all is back to normal with regards to hydraulics. Was able to lift a 1500# hay bale to full height. Have not seen that in nearly 2 years!
