Wd45 hydraulic pump.I rebuilt this pump over a year ago.I had 3200 psi when the unloader valve would kick out.I had no problem with traction booster until yesterday.We were having a plow day.Made one round in field traction booster was working great went to lift plow out of furrow and it would only lift about 2" and pump would kick out. Any ideas what happened?
Thanks,
Chris

Pressure check it to see if the 3200 psi isn't there anymore. Did you clean/wash/flush the hydraulic sump while the pump was off ?? I'm thinking a lug of dirt somewhere. You might try it again when cold and see how things go. Also, make sure the hyd is full of oil. Maybe the clutch shaft seal has leaked out the hyd oil into the tranny area.
