moe1965 737 #26 Posted June 8, 2023 I'm interested in knowing how hard of a job it is to replace the axle. I have the same issue on a B100 as well for now I welded the slot where the half moon key goes and took a small Dremel with a small cut off wheel and made a new slot. Took some time. If that doesn't work I might swap out for a new axle. Share this post Link to post Share on other sites

If that doesn't work I might swap out for a new axle. Well I took the transmission apart today and really it's quite simple to change the axle... You can leave the hydro unit in place. I had a bit of trouble getting the axles out because where the snap rings are the splines mushroomed up on the backside and I had to file it down to get the gear off the axle.

AlexR 627 #28 Posted June 10, 2023 Got the transmission split today. Had some trouble getting the axles out of the housings because of the ends being chewed but ended up filing it down quite a bit and then just hammered it through because I figured I would just get new bearings... The splines behind the snap rings were mushroomed up so had some trouble getting the gears off. Otherwise it went fairly well, the inside of the case looks excellent. I did find a broken tooth in the case so I was going through all the gears and couldn't find any broken teeth then I remembered the parking brake and yep found it haha. So now onto the issues so I needed 2 axles 2 hubs case gasket, new filter, seals, 2 end bearings and 1 carrier bearing was also bad it had a good bit of play in it. And then if I actually wanted to get a new parking pawl on top of that, it was adding up to quite a bit, and considering it was a 1" axle 4 pinion transaxle. So I am getting two part transmissions for sunstand hydros instead. Both I believe have 1 1/8" axles. And 8 or 10 pinions. Not going to get it for a little while yet though. So while I wait for that I will be working on other things on the tractor, I am going to repaint the frame and touch up some other spots. I do have some welding to do as well the transmission plate does have some hairline cracks. The belt cover is broken at the engine mount. Repaint the rims change the rear tires and I got some penetrol I am going to try out on the sheet metal paint. Share this post Link to post Share on other sites
c-series don 8,687 #29 Posted June 10, 2023 @AlexR did you happen to take any pictures of inside the case? I’m just wondering what it looks like in there! Share this post Link to post Share on other sites

AlexR 627 #32 Posted June 10, 2023 (edited) Well it's all pulled apart getting stuff degreased and cleaned up. It really didn't take too long to take apart. They made them pretty easy to work on. Took down the wheelhorse branded rear tires that are the bigger size to put on as well. Edited June 10, 2023 by AlexR Share this post Link to post Share on other sites
AlexR 627 #33 Posted June 18, 2023 (edited) There was a couple cracks on the transmission mounting plate welded the cracks up and then will get a 6x6 plate probably 1/4" thick to back it. Also the tab on on the belt guard where it mounts to the engine was also broken off so welded that up. And then painted up the rims and some other parts that were pretty rusted up.

AlexR 627 #36 Posted June 29, 2023 Got it put together as much as I can for now, I could probably start it up and run it now. I do need to drill holes and paint the 1/4" backing plate for the transmission yet though. Also may notice I straightened the dent in the front of the hood out. I do have a question though for the "brake" which seems to just be a neutral position locator. Do any of you guys have a picture of how you ran that spring? I think mine might not be the original and it's probably to long. It was just ran on the outside with a hose clamp on the rod. Share this post Link to post Share on other sites
AlexR 627 #38 Posted August 4, 2023 (edited) Got 2 sundstrand 90-2046 transmissions for a very reasonable price both are limited slip. And they are the hydro gears the one is in pretty good shape I am going to install it and see how it runs getting it painted up incase I keep it on. The keyways aren't to bad, one side is tight the other is a tad loose. Side to side play isn't bad either. Getting a 1410 napa filter and some axle seals for it and going to change the atf fluid in it. And also some set screws and a bit and tap for adding set screws 90° to original ones. The other 90-2046 transmission has good keyways but a lot of play side to side on the axles I'm thinking of taking that one apart and see if its in good enough condition to use and switching the hydro piston to piston that was on the tractor onto the transaxle and keeping the hydro gear for parts for the other one.

AlexR 627 #39 Posted August 5, 2023 And she is back together and running!! Got the new filter on, new fluid in the hydro. Tested her out ran her around a while before testing the hydro and it's strong. Will post a YouTube on that in a bit. It's pretty much done, going to pull the hubs back off change the axle seals, drill and tap for the extra set screws on the hubs 3 2 Share this post Link to post Share on other sites

AlexR 627 #41 Posted August 5, 2023 Can anyone tell me if they make the circled part anymore it's like a flexible spring plate for locating neutral on the motion lever. Or what it might be called. I have tried searching for it and can't find it. Share this post Link to post Share on other sites

No longer available, but A-Z Tractor might be able to find you a good used one. Edited August 6, 2023 by rmaynard 1 Share this post Link to post Share on other sites

I know it doesn't need to be there but it would be nice having it for the kids and wife. 1 Share this post Link to post Share on other sites

Surprisingly this one actually didn't take as much of my time to fix up as I thought. But it was probably still over 20 hours. 1 Share this post Link to post Share on other sites
