Got it started

So I got this started yesterday and having issues getting the coupler off the shaft (surprise, surprise ). At least 3 years ago the PO told me he had bent the shaft and had replaced it so this drivetrain have been taken apart before.
So far, I have put penetrating grease in it and tried with a 2-bolt puller to get it off. I have not wanted to use the transmission coupler as a press for fear of bending or breaking. Well, I've already broken a bolt with so much tension. What do you think for my next attempt - use heat and keep pulling or find from flat steel and make a 4-bolt plate to pull against? Here's some pics: You can see my homemade coupler wrench that worked pretty well. You can also see the bolt I snapped off.

Couple has some corrosion as you see. Probably some corrosion on the inside as well. I wouldn't try to force it off too much. Spray some more penetrating oil... keep the tension on it. I would heat it, use penetrating oil and tap at it while under tension.

Is the key still look lined up straight?

Will probably take a be a few days before it gives way.

Thanks Mike! Key looks to be in good shape and lined up fine in key slot.
When using heat can you cause harm using too much? I've got a torch I can use. Also, will it pop off or just gradually start sliding off under tension? I put a small Sharpie line on the shaft to see if I was making any progress at all.

It will pop... had this trouble on a benz with wheels not coming off on rotation...

regarding heat... I would just heat the union of the coupler and shaft... some one else here had the same trouble - took a few days but it popped off... heating the union should help penetrating oil to get deeper...

Heat and tapping the coupler when under tension should break it loose - I am always amazed how a little corrosion will lock something up when there are tight tolerances.

Darn can't find the thread.

Man, the more research I do leads me to more questions. Do most people heat the couplers in the oven to expand them to refit/reinstall them or just crank down on the nut real tight? Also, is it recommended to use some anti-sieze on the mating surface for future removal? thanks a ton for the help so far Mike.

Anyone ever deal with this type of flange? Of course I don't have a socket big enough to fit...but is that all it is and it slips right off? Reverse theads? Anyone know size? Thanks.
