1450 Driveshaft Problems

Camper-1 · #1 08-31-2011, 10:58 PM

I recently bought a 1450. I was told that it had run in the spring of this year but Hubby decided it needed fixing. When hubby was caught throwing wrenches in the shop the better half decided to sell so she could have her side of the garage back. So I gave her the money and loaded the tractor and baskets and boxes and hauled it home.
when I started to unload I found big puddles of oil and tranny fluid. My wife met me in the drive and asked where I was going to put it? If I wanted to keep it I would have to get rid of the 127. Things were not looking good.
Anyway I found that there was something wrong with the driveshaft so I pulled the motor and got the new parts but my problem is I am not sure what should be on my cub. Hubby had put on new rag coupling but he used 2 at the rear and I think it should only have one. He also put a bushing on the end of the shaft which I think took all of the flex out of the coupling1450 cub cadet 007.jpg There seemed to be another bushing like it in the end mounting bracket. If I dont use the bushing then I could use the 2 rag couplings. Also I think I should have a ball bearing in the hole in the mounting bracket Not sure what is right1450 cub cadet 007.jpg Sorry that the pics are so blurry but I hope you can see enough to help. The pics that are clear are too big so they will have to wait for another day.
Thanks Ken

Unfortunately the picture is too blurry for me to tell if that's part of the ball bushing that belongs in the coupler (although it'd be broken if part of it is there) or some sort of PO mod. Try holding the camera further away from what you are trying to photograph.

I do know that IH started putting two flex discs at the rear on later models. So that may not be a mod.

I will try another picture today from farther back.
Sorry that I didnt respond last night but was too tired and signed off soon after posting.
My serial number is 2050660u579563. Do I use the single disk and ball or the double disk or do I just choose one way and run with it.
The drive hub on the flywheel was ripped off when started up from repairs and it was at this point that I was able to purchase it.
Thanks for responding

I Just put one of these driveshafts in a 149, it came out of a 1250. If yours came to you in pieces, I would have a few suggestions for you. First, verify that your isomounts are good. Next step, you are going to have to get the shaft back in the tractor, with all associated parts (no flex disks, yet), and measure the space left over at each end for the flex disks, they are roughly 1/4" thick. Your driveshaft length will dictate how many FD's you will need, don't forget that your rear coupler has a ball bearing inside of it for a spacer.
I haven't done the drive shaft install/ removal in a 1X50 tractor, but on my 149, I did it by removing the rear motor mount bolts, and loosening the fronts. This allowed me to rock the motor forward and install/ remove the shaft with ease. I would think this should also work on your tractor, leave the isomounts bolted in, actually remove/ loosen the bolts from the motor itself, I doubt the isomounts being loosened/ removed would allow you to rock it enough to get the shaft in and out (the rails that the engine/ isomounts are bolted to are pretty long, when you try to rock it that way, the rear of the motor would move up and down drastically just because of there length). I hope this helps, I know from hearing from others that the flex disk numbers and arrangements vary in these tractors, without seeing it together, the only way to see how many you need is by putting the driveshaft in and measuring it, it's over all length will dictate how many FD's you need, and make sure once it's in there, to put the rear if it up against the ball bearing spacer.

Whew, I was kind of long winded, hope this makes sense and helps!
