Changing a transmission

Postby Ben B » Tue Jun 12, 2018 1:41 pm

I looked on the sight but didn't find anything to answer my question, but can the transmission be changed out without having to split the tractor? Yes, I realize I must drop the finals, and the axle tube, etc. And, no I've never done this before but it looks pretty straight forward. I want to be sure I don't miss something in the process, and that is why I ask. I know there's always surprises hidden in any mechanical endeavor.

Any suggestions and advice is welcomed! Thanks!

Be sure and wedge your front axle! Yeah you can change it without splitting it, the hardest part will be trying to get the transmission shaft back in the center of the clutch but it can be done because it sticks out so far.

If you have a helper, it's pretty easy to guide the driveshaft back into the clutch.

Basically, whenever the front is disconnecting from the rear, the tractor is being split. So short answer is Yes it has to be split. As the others said, not a bad job with a helper. There have been a few done at the Bash.
It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

If you look in the service manual, I believe it is called a REAR SPLIT.

Thank you everyone for the information!

The old transmission is out, and the "other" one is mounted up and bolted on the tractor. Now, I need to get a couple of seals for it before I finish assembling everything else.

I followed the service manual's rear split procedure, plus removed the rear wheels, final drives, and axle tube. There were no surprises, which was good! My oldest son helped me get the replacement transmission lined up and bolted on, and that completed the evening's work.

I pulled my transmission, rebuilt it, and reinstalled it all by myself, without a cherry picker. It CAN be done!

You must be as stubborn as me! :lol:

Well, I installed the transmission with the help of my oldest son. But, after looking at another thread, I have discovered that the front oil seal retainer is backwards with the bulged side facing out. So, I guess that means it has to come back off the tractor.

Therefore, I'm going to go ahead and rebuild the transmission now and be done with it! Then, that will only leave the engine to deal with, which so far is still pretty strong. The engine needs seals, but does alright otherwise.
