Danz77 0 #1 Posted September 7, 2016 I'm trying to help my uncle find a pump or parts for the pump in his 1973 wheelhorse D series Model 1-0610-8. The hydrostatic pump is the 90-1137 and it needs a new shaft and shaft seal. The parts I found when researching are : Pump shaft - 200213 Pump shaft seal - 7877 Shaft snap ring- 83-3870 Also if possible : Shaft bearing - 200214 Snap ring- 200215 Would like to rebuild it or if possible locate a working pump to replace it. Any info will be greatly appreciated. Share this post Link to post Share on other sites

I think he has to machine the valve plate for the pump or motor i can't remember which and he didn't really want to do that when i contacted him a couple years ago. Hold on when you find out the prices. The bearings and seals are not a problem to get. I have numbers when you get ready. This is not a quickie project. The are some threads here about rebuilding the sundstrands. If the pump is bad I can virtually promise the hydro motor will have issues also. 1 Share this post Link to post Share on other sites
Danz77 0 #3 Posted September 7, 2016 The one part that will solve the biggest issue is the shaft seal 7877. It leaks. Otherwise the rest can be delt with later. Share this post Link to post Share on other sites

Do you have the manual? http://www.wheelhorseforum.com/files/file/24-transmission-hydro-sundstrand-sm-492-4206pdf/ Edited September 7, 2016 by pfrederi Share this post Link to post Share on other sites
