Removing the sleeve on the Y mount

What is the best way to remove the old steel sleeve from the transmission Y mount bolt?



I am guessing that the untreaded part of this stud is tapered? After 35 years it is frozen, so what would be the best way to remove it.
I watched a Utube video which showed how difficult it was to remove, cut off saw, chisel, and torch!
I was thinking of using a Dremel cutting disc to cut along the length on two sides?

I would remove all the rubber I can first (including those transmission mounts), and then get it really hot with a torch and spray PB blaster into the opening on the top. Make sure to do this down-wind. Let it soak as it cools, then put the y-piece in a vise and clamp a massive set of vise-grips onto the sleeve. Then give it all you've got.

If it were my part, I'd submerge it in evaporust and leave it for a day. Should be loose the next day. If you do evaporust in an ultrasonic cleaner, even better results. Clean off and paint afterwards of course.

I wish I knew about this rust remover a few months ago! I have been soaking my small parts in lemon juice overnight after wire brushing them. Evaporust would be perfect for larger parts like the Y bracket.
Thank you for tip.

sleeve removed!

Here are a few pictures of my removal process.


Used a cut-off disk and cut two slots 180 degrees apart.


Then used a nut splitter on both slots, working from front to back.

As the sleeve split apart it finally came loose!

Man, that was stuck. Looks like it cleaned up pretty nice though.

Agree with Pyroman, it cleaned up nicely. Looks almost like new. Would recommend putting some antisieze on that stud during reassembly.

I will be coating all the threads and the stud with anti-seize lubricant for the next person who takes it apart!

I do not have a concern about these parts coming loose after using anti-seize lube on them, I will be torquing them all to the recommended specifications in the manual!
It will take a bit more time to assemble, but it will give me peace of mind when I am doing a top speed run on the highway! 135 mph from such a little powerplant is crazy!

I used a copper anti-seize lubricant on the sleeve to prevent the seizing of the sleeve to the bolt for the next person who takes it apart!
