TJ 184 #1 Posted November 19, 2008 I just finished rebuilding and cleaning up a Uni-Drive transmission off a 633 parts tractor. After filling it with 80/90 oil, a hairline crack became visible on the small half and it runs about three inches across the lower middle bolt hole. My question is; can this be welded or repaired, or am I the proud owner of a lot of good transmission parts. :D Share this post Link to post Share on other sites
sorekiwi 761 #2 Posted November 19, 2008 I'm having trouble envisioning (sp?) where the crack is. Can you post a picture? Cast iron is weldable, or can sometimes be "plugged" with a series of screwed in studs. Probably cheapest just to change the case(s) if the internals are good - there's plenty of good cases around with bad internals (or cheap transmissions with unknown internals). Where are you located? Edit: sorry just saw your location. Are you near Dale (thirdroc)? He had some transmissions he was trying to move. Share this post Link to post Share on other sites
BPjunk 184 #3 Posted November 19, 2008 Ok first we would need to take a look at the crack, from what you discribed it might be repairable. A good welder with a nickle rod might do it if you preheat the case before welding. I gather this was a frozen water in the transmission type crack (I saw the word Michigan in your signature <_< ) , it is posible to swap in another right side housing. If you need one let me know as I have a used extra from the Uni-Drive rebuild article I am doing for Lawn and Garden Collector Magazine. Wild Bill in Richmond, Va.

Michael Bullington 5 #5 Posted November 19, 2008 I had one welded once,,,the price wasnt bad ,,and it was easier than replacing the trans for me. Michael Share this post Link to post Share on other sites
TJ 184 #6 Posted November 19, 2008 Thanks for all the responces. I would post pictures, but I don't have a clue how I would go about doing it. I am almost completely computer illiterate. :imstupid: The transmission was filled with water and thats what I figured cracked it,too. I think you guys are right. The easiest and best fix is to just replace the shell with a good one. :hide: Share this post Link to post Share on other sites
