We recently had our hydraulic pump rebuilt on our Prentice 384log loader. We are now experiencing problems with our loader working in general. The turn is slower, the boom will barely move and the grapple will barely open and close or spin. But when you are running it,if you step on the turn pedal and work your joystick at the same time all your power and speed comes back. We are lost on where to even start figuring this out. If you have any suggestions please let me know.
Not familiar with your loader but it sounds like a signal line is not hooked up and pump is not up stroking until you signal via swing valve.
Hey, this is James H. and I would like for you to please contact me via phone @ 601-764-7675 or via email [email protected] so that I can talk to you about the problems you had with your 384 Prentice you had back in October 2014! I'm having the same problems with mjne currently and would like to know what you done to fix yours.
If I remember correctly those are a two stage gear pump. When they rebuilt the pump, the center section got put in backwards. Tear it apart and turn the center section around so the drilled passage is on the suction side and it will work fine. What happens is with the drilled passage on the pressure side you have to use a function from both pumps to bring pressure up.
