I may have to. Thanks

Raising the loader slow "can be" a pump issue. As can no down pressure. But not holding the load up...has nothing at all to do with the pump.

Agree with above. If you ain't comfortable diagnosing hydraulics....have someone diagnos it for you. You can spend a fortune replacing parts that ain't needed, because there ain't much in a hydraulic system that's cheap

Yep, I am finding that out.. lol Thanks

If you ran the pump without oil then there's a good chance you did damage to the pump. You could remove that cover to the pump and inspect inside the pump but be prepared for oil to come out. If you do remove the cover you can measure both the diameter of the gears inside and their thickness. That'll give you the displacement of the pump. You can find cubic displacement calculators for gear pumps on line. Just find one before you take the measurements so you don't miss a measurement.

Thank you. I will look into it

Hi, I have a Massey Ferguson MF-50 with a freeman 4000 FEL, it has a front mount pump that I believe is going bad. My question is, what is better to use a single stage pump or a 2 stage? according to my manual it requires a pump that can put out 18gpm. Any help would be great.
Thanks Tim

18 GPM at what output pressure and at what RPM? You need all of those numbers to properly select a pump.
