A transmission seal

cheif · Jan 16, 2012

I need to replace the front transmission seal on my international A. My service manual is not very clear to me on how to access the seal . Must I split the tractor at the clutch and move the engine forward then split the housing at the transmission? Can I then remove the transmission drive flange to access the seal or do I have to disect the transmission further?
when I pull the engine forward will the clutch shaft just slide out of the throwout bearing and release sleeve?
This is a 46 model and I have replaced the final drive and axle seals, they were still the original leather type and very leaky. I suspect the transmission seal is the same type.
Thanks for any advice!

Chief,

If you know the clutch is in good condition, it is best to use hoist and/or splitting stands or good blocks, jacks and split at the transmission letting the drive shaft pull out of the clutch. Once you get about 4 to six inches of separation you might be able to unbolt the drive shaft and leave it sticking in the throwout bearing tube. If so, tie up the back end of the shaft and don't put any pressure on the throwout bearing tube as you could break it. Do not release the clutch as the alignment with the pilot bearing will be messed up. Then remove the nut on the transmission yoke. Good idea to inspect the coupling and replace worn parts. Trick is getting the shaft held up to go back into the throwout bearing tube in reassembly if you go too far and the front end slips out of the throwout bearing tube. A three ft piece of garden hose (or similar) slid through the throwout bearing tube and down through the clutch inspection/adjustment hole, then slid over the pilot bearing stub on the shaft can serve as a guide.

Thanks, I would never thought of that.That A is my winter project, maybe I'll need a long winter to fix all the leaks!
