I got a new quad ring and put in it to stop the leak. Now I'm wondering, there shouldn't be any oil in the center, because it is pushed from each end. Is this right? If there is oil in the center part, it has to be leaking around the piston end, or am I over thinking this. Just thinking I should get a seal kit for the steering unit and go all the way thru it. It drove alright before, just leaked oil out the bottom. Thanks, Chris [Reply]   [No Email]

If it has been converted to hydrostatic steering it does. If it has the original power steering unit (has a solid shaft between the unit and the steering wheel) it will not. However there is also a seal in the bottom of the unit [Reply]  [No Email]

The pinion gear requires lubrication. The cylinder center should be half filled before you put the cap back on. [Reply]  [No Email]

It was leaking a whole lot more than that, the whole front of motor and around the steering unit was caked with dirt and oil. I needed to check and add hyd oil regularly. Chris [Reply]  [No Email]

I noticed my narrow front tires were getting some hydraulic oil on the inside of them the other day. If so, how hard to fix? Thanks Reaver [Reply]  [No Email]
