I'm hoping someone with more expertise than me (won't take much) can point me in the right direction. My loader on my 9N isn't getting any pressure (now). I think it warrants a story and some observations I have made.
Initial situation. One week ago the loader was working fine with one problem. The pump was leaking pretty significantly. I was still able to use it but was disturbed by the amount of fluid pouring out of the pump. I also noticed that the drive shaft seemed misaligned. I took off the pump and the connector to the drive shaft. The connector was badly worn so I got a new one of those and have installed. As for the pump, I opened it up to look for any obvious issues such as a missing or badly worn seal etc, but didn't see anything. I took it to a nearby implement to have them take a look and see if they could replace seals etc (they couldn't get new seals). Now the pumps that came on the WM3 are pretty simple, not a lot too them (my point is I'm pretty sure it's put back together correctly, not much you can do wrong?). I decided to put the pump back on and align the shaft hoping that the misalignment was causing the leak. Did that. I also drained out all the fluid and changed the hydraulic filter (naturally I drained the fluid, it all came out with the pump off!). The WM3 is supposed to hold 5 gallons, only half that drained out. That didn't surprise me as it was leaking so much.
After everything was hooked back up I refilled the fluid. Thought it was odd that only 2-2.5 gallons fit back in too. When I drained it I did so from the feeder hose that goes into the pump, I also took out the drain plug next to it (didn't see any strainer as mentioned in the manual).
So I started it back up and noted the alignment looked great now. Also didn't see any fluid leaking from the pump. Great! Or not. Tried the hydros and nothing. nadda. Not knowing where to start I took the pump off and could tell everything was still turning as expected, couldn't see any issues.
Wanted to test if there was pressure coming out of the pump, so we actually unhooked a hose just upstream of the pressure side of the pump and went behind a blast shied to just crank it and see (kidding). What happened next confused me. The fluid didn't seem to come out with high pressure, but rather hydraulic fluid came out of the air hole at the top of the loader/reservoir, the non pressure side. I have NO clue what that means but maybe it means something to someone else.
Not sure where to go next. I'd say pump for sure if it had not been working days earlier (but before it was taken apart and inspected), and the fact that I only got 2.5 gallons in, and that strange pressure relief in the reservoir when the pressure side was open. Any ideas are much appreciated! Thanks! I can post pics if any are needed.
