Super M stage 2 reservoir

My single acting control shaft leaks where it goes into the res. I know there is an o- ring there but has anyone had any success fixing that leak
without taking the res. Apart? Thanks DTK
 
Got the same leak problem with my Stage 2 SM. Waiting for someone else to share their experience succesfully fixing theirs before I tear into mine(!)
 
Replacing the O ring requires taking the back off the unit. Then a pinch bolt with a washer that goes in a keyway is removed from a short lever on the inside and the operating lever and shaft removed and then replace O ring. Pretty easy so far but a little more difficult putting back plate and valve body back on. Tube with O ring on each end goes from pressure port to valve body, plus the inside operating lever goes in a slot. Back plate needs positioned to get tube and valve body operating linkage lined up, can be tricky or everything falls in to place.

slater can this be done w/res. Still on tractor? Thanks DTK
 
It can be done on the tractor BUT, it is more difficult. The steering post is in the way and I cannot remember if I swung the post off to the side or not. I am thinking of SMTA but think regular super m would be same. That crappy gasket is also a problem unless they make better ones now days.
