Just saw your post in the want-ad's, have you tried contacting Klaus at Top Hydraulics for that 'O' ring? If he doesn't have it (I suspect he does), maybe he has the part number and where you can get it. Good luck!


Klaus sent me cylinder port o-rings so I could finish the install. Great company! You have to be careful installing the hydraulic lines because it is easy to tear the o-ring. My rebuilt pump works great and no leaks. Anybody that is handy with hand tools can do this.
