Prater 75 #1 Posted May 25, 2012 I have a spare sundstrand from a working D series tractor, before I put it on my D-180 I would really like to send it to someone who works on them and have it rebuilt. Anyone here work on them? I have a rebuilt pump motor, just looking to have the pump done. Maybe I will get to use one of my D's before the year ends...

shootinok 15 #2 Posted May 25, 2012 When I got my first WH the pump motor had been giving the previous owner trouble. He tried to take it off but instead separated the aluminum case from the motor housing allowing all the fluid to drain out. Then gave up on it and it set for a long time, allowing dirt to get inside. I found a place that rebuilt the Sundstrands but they quoted me $1000 - $1400 depending on what they found when they got it. So I decided to take it apart and learn something. I found the manual online and it was really a cool learning experience figuring out how this thing worked. Many of the parts are no longer available, but the gaskets are. My understanding is that most failures are from clogged valves or from scratched or damaged thrust plates. I can’t really call it a rebuild but I was able to completely clean everything, and I sanded and polished all the scratches out of the thrust plates. When I got it all clean and put back it together it is as strong as an ox! Guess what I’m getting at is… Don’t be too intimidated by them. If you have good mechanical abilities, you can do it yourself. I actually enjoyed it. 1 Share this post Link to post Share on other sites
Prater 75 #3 Posted May 25, 2012 Thanks for the encouragement. I will pull mine apart when I get time and see if I can take care of the problems, my real problem is finding the time... Share this post Link to post Share on other sites
