wagner wm3 loader quit, rebuild kits?

9ninmi · Oct 6, 2015

Hi all,

so I got this here wm3 wagner loader mounted on the ol 9n,
we had some storms and wound up with a lot of wood chips. So I was working away with this tiny bucket (planning on adding tines to it in the future), after a few hours of work, on and off: I came into the pile with the hydraulics working fine, and when I dropped the bucket to scoop: no response.

I have checked the filter screen, and even cracked the top lines near the controls to check for air/try to bleed, nothing.
There is no resistance on the bucket lever, and minor resistance on the lift. Where as you could feel the pressure before.

So, I'm thinking the pump has gone out and its bypassing,
any opinons or comments on that?

and does anyone know where to source a rebuild kit? again, its a wm3 wagner crank shaft driven loader.

I may have this and another 9n as a package deal up for trade if anyone has something to offer.......

I have had that happen more then once and it has been a bad pump drive shaft that caused the problem. Get someone to help or tie the control back and fire it up and watch an make sure the pump is spinning. You have to do it that way because with out calling for pressure the pump can turn just because of friction but stop when it needs pressure

Pump pressure generally has nothing to do with control lever/spool resistance. Invest in a pressure gauge so you have some hard data from which to work.
