leaking hydraulic pump.another question...

Think I know the answer, but would running something like a quart of ATF or an engine stopleak do any good to swell the seals and slow/stop the leak? Since I know what the problem is and the hydraulics work (and I have 10/40 for hydraulic oil) I am doing as someone suggested and just keeping the hyd reservoir full and the engine oil level sucked down. I'll know in a week or so how much it is leaking.

Thanks, Dave

Dave. Suggestion. DON"T! ATF will thin out when warm. Hyd seals (what size??? ) would be worth taking pump apart and installing new seals. We could have short cut our rebuild Hyd Pump on the O.C.46 ,but with the large cylinder(lift) and the 2 (dump ) cylinders and the lifting pressure needed to do the bucket lift ,if quite high. 13-1400psi.
I would WAIT WAIT WAIT to see if any one ( we gave ya the names) to see if they could supply you with the seal /a/or/repair kit. There HAS to be some repair station that has -or can get the kit -or at least a new pump at a reasonable price. Even an out of block pump could be the answer if all fails. Sure wouldn't take the chance of an over fill and blowing out seals in the front main or back main seals in the engine. Would hate to hear that .Sounds like the engine you are driving the tractor with is good to go except the Hyd pump that bolts to the internal cavity causing you to have overfill when the seals on the pump are leaking.Trying to guage (if you fill and drain as you said) the amount of fluid that passes into the engine would stay at a stable amount rather then the seals deteriorating then Un be known to you, more fluid is entering the engine chamber making more pressure on the engine seals .BOOM!!!!!!!!! Out they go. Now you have more additional problems then what was the original . I personally would do an out side pump assembly wayyyyyyyyyy before I would even attempt to keep adding and subtracting fluid to maintain some sort of pump stability. JMHO. Regards, LOU & VICTOR.

Thanks Lou. Have a guy giving me a used pump if it's the right one. Should have it by midweek. If it's the same, I'll put it on the tractor and open up the leaking one to see if it can be fixed. Or, send it to my brother and see if he can get it fixed. Having a real hard time with the replacement pump only that the parts guy is telling me. If pumps are being produced, there has to be parts. Just much easier to relax and look when the tractor is working.

Dave . we know the feeling . It's sure as H--l easier to relax knowing the season for spring is fast approaching,AND THE TRACTOR IS GOOD TO GO- NO PROBLEMS. Sure hope the pump problem works out for you. Any thing we can do to help. you know how to reach us.Like I said, "I may not be the sharpest knife in the drawer.but still can cut it. OH by the way. seen a couple of foolish posts trying to be superior minded and brilliant writers. These jokers aren't worth any reply. Seem a padded rubber room or a long coat with tie behind sleeves would be of great benefit to em. Warmest regards LOU.
