Hyster H3.00XM:
Hydraulic pump

I have just changed the hydraulic pump that goes into the transmission under the left side foot well. All functions are very slow until you give it gas. Also screeching noise coming from transmission when tilt and sideshift are operated. Any ideas?
Thanks

It sounds like there is a problem internal to the transmission. A gear pump has fixed displacement, so each revolution displaces the same volume of oil. If the displacement is low there must be something slipping in the pump drive.
