Unfortunately you are trying to do one of the most difficult jobs on an oddy.
In my opinion you are going to have to remove the trans. Just my opinion.
Everyone always tries to do things the dog F'er way but I think it will just cause you grief.
If you tip it on it's side and silicone a plastic (cut bottom end of first) bottle on the end and then fill it with PB and let it soak for a few days, then try again. I read that here somewhere.
I have never had to do this job yet but if I do I will be using a bearing puller (see pics) and try to pull it from the very back. May have to make my own custom puller.
The diameter of the sheaves is too big for something like that.
Also be careful with that bearing splitter putting pressure against the case and cracking the case. There's not all that much space between the clutch hub and the case.
My recommended scenario:
1. Remove trans.
2. Gut your trans and isolate the case half with shaft and clutch (easier to work with)
3. Use some plumbers putty to make a "reservoir" atop the shaft end (exterior/clutch end of the shaft)
4. Fill the pool with penetrator (PB Blaster, Lucas Penetrating Lube, etc) and check it every morning. Refill as needed.
5. Give the shaft a few light taps every day to try and work the lube in there and shear some seize.
6. Do this for 3+ days.
7. Try to remove.
8. Once you get it all apart, go ahead and replace your input shaft bearings while everything is yard sale'd.
I've even thought of putting the INTERNAL side of the shaft in a coffee can of dry-ice to shrink the shaft (or if you have access to liquid N). The shrink will break some of the rust bond, too.
Maybe even put the whole thing (case half, shaft, clutch) in the oven (not your kitchen) at 3-350 for 10min, remove and let cool, 10min in oven, cool, a few reps. The expansion/contraction may work the corrosion apart. It will also boil the penetrator and kind of give the area a nice "gargle" of fluid, lol. Beware: I don't remember if that side oil seal is the "hard to find one" or not. And the helix slider caps are plastic.
Don't pry off the case shell.
Don't flame-torch the crap out of the clutch.I got lucky on the one I've disassembled successfully. The other one is still stuck and on the shelf.
