MF 30 Industrial Hydraulic quit. please help

georgia088 · Apr 19, 2018

Hello all.
My MF 30 Industrial's hydraulics just quit. I was digging with the backhoe under normal conditions, and all of a sudden I just felt the pressure quit in the controls. Nothing hydraulic would work any more. I didn't see any major leaks (I have a few small leaks that I have had a while, but nothing major). I don't know a lot about hydraulics, but could anyone point me in a direction of what I could check?
Thanks!

Ok. You were spot on. BUT... the shaft and coupler are both stripped out. My problem is i'm nit sure how the coupler comes off. I hace the pump side off. The shaft just pulled out if coupler. However, the coupler is still on shaft from other side. Please tell me it comes off and isn't made on to the shaft? Also, can you buy just the shaft that comes out of the pump? Or, do you have to replace the entire pump?

Thanks!

Try to turn the shaft in the same rotation of the engine to unscrew from the frontpulleyadaptorplate.
