Allis Chalmers WD45 Tranmission/clutch

Anonymous-0 · Nov 23, 2012

I have an Allis Chalmers WD45. I bought it last summer and it shifted fine. Now a year later, the shifter now hangs up between gears and when I push in on the clutch to shift, it will not shift. It's like the clutch does not stop the transmission. O have to shut the tractor off to shift the transmission

Does anyone have any suggestions?

Thanks

Get an I&T or Allis manual and read up on adjusting the clutch. If that doesn't work, read up on removing the engine and replacing the clutch.

Can you sift if you use the hand clutch or is that what you are trying to do. The Foot clutch if adjusted as it should be should let you sift with no problem but if not adjusted right and it still tries to move with the pedal down you may have problems. Either way you should be able to shift gears with both clutches

The free play on the pedal needs to be no more than 1.25inches. If you push it with your hand till it feels hard to push the pedal should move no more than that from the stop. If it is adjusted correctly, the pressure plate may be getting warped, or the pilot bearing might be going bad causing drag on the trans input shaft making it spin when it should slow down. Jim

Yeah! Iv'e got that job to do, and have been asking questions, over on the Allis forum, as well as reading the IT manual. Worst part for me is that I have to take the Duall loader off, and pressure wash all the muddy chicken poop off of the deck, and front and rear tires, before I can get close enough to work on it. Then after changing the clutch I still have 75 yd's of manure to spread. Gotta have a second loader tractor!

One thing I haven't seen mentioned here is that the clutch disc hub splines can become rusted on the transmission shaft, this causes the disc not to slide back away from the flywheel when the clutch is pressed. There's really no cure for this other than remove it and wire brush the shaft and replace the disc. Even if the clutch disc lining looks good and thick enough look at the splines in the hub for wear. I've cut my fingers on these splines trying to remove these clutch discs on forklifts because the splines were wore so thin they were like a knife blade. This makes the clutch rattle also when the clutch is pushed in.
