Danny, my broken 140D does not have the powershift. Not sure if that was an option or not. I think the 147D models had powershift.

PS. I'm bummed about my broken tractor. I find myself day dreaming about a new, bigger, tractor.

I was thinking YM147, keep an eye out on ebay for a YM140 parts tractor.

Now seems like a good time to get it

Found some time today to tear the 140D down. Pulled the tranny cover off and found that the forward bearing on the speed shaft (just in front of drive gear) seized up and tore up the innards consequently driving a few balls and part of the raceway into the cover. This caused the crack in the cover. I need a new bearing, a few gaskets, and some JB weld? Other then that the gears, etc. looked mint! I figure I have a 50/50 shot at getting it back together. Posted some photo's in both large and small formats. Hopefully the smaller pic's won't bog down all you folks with dial-up. Git er dun!

Ernie, does the YM140D and YM1401D have the same trans?

Dave, I thought he meant 1401 I dont think they are the same tranny.

Oh well !

I think the cover could be fixed, welded and machined. Ernie, I thought the same thing at first, and I think I have a YM1401 trans, but it sure is different.

Today I had a friend repair the broken tranny cover with an aluminum weld since I didn't have a snow ball's chance in **** of finding a replacement. Now I need to find a seal and new thrust bearing. Shouldn't be a problem.

I'll need to make two gaskets however. Any advice on how to get that done? Any kits or anything similar that someone has had good luck with? I suppose I can go with Permatex form-a -gasket if all else fails.

It must be nice having a tractor where getting parts is as easy as going down to the local shop and ordering them. I'll guess I'll keep going MacGyver on my trusty 140D for the foreseeable future.

Well, having a Yanmar is not for everyone, but I must say I am proud of how you are handling this. You are the right type to have a Yanmar. It takes some skill and some creativity, and you are doing great. We can weld aluminum or steel and we have a lathe and a few other basic machine shop type tools, and with a little patience, it is amazing what can be done.

Might want to check Hoyetractor. I think he has a gasket making machine now.

Jim, I thought that you needed the transmission housing, the cover is available and it is a lot less than the housing. The gasket is no longer available.
