I have a 1993 Bobcat 642B with a Vickers V10 hydraulic vane pump. It had only 1200 psi so I tried to adjust the bypass but still only 1200 psi.
I bought a rotor, vanes and pressure plate and installed into the pump. Still only 1200 psi. Hydro works great. Loader has good drive speed.
Just slow hydraulics with lack of pressure. Any help would be great. Thanks
