XR 7 Super Z Hydro pumps

[tjcezar]

I have a Hustler Super Z XR 7 that the top caps on the hydro pumps were leaking. When I removed the cap the o ring looked flat and square but the dealer said they used to be round. They gave me new round ones and I installed and tightened everything back up. Started er up and worked the levers and they both started leaking bad right away. I then toiok the one side back off just to check that the o ring was ok but everything looked good so I reassembles and tried it again. This time nothing worked. Does the system need to be bled somehow? Where can I get a break down for those hydro pumps also.

Get the back wheels off the ground and operate the hydraulics, the air will purge itself. I'm not so sure you don't have more problems than a small leak, let us know.
