My son bought a salvaged 1994 V6 mustang for $800 2 years ago. Had/has a few problems but runs well and was a great car for him in high school and when he is home from college. He is home this weekend, and it broke down on him. He drug it home and handed me the crank shaft pulley! It would appear the bolt in the middle that holds it on came out. Easy enough to reinstall. Except...the collar that fits over the end of the crank is broken off flush with the oil seal. Does anyone have any ideas about getting the broken end of the pulley off of the end of the crank shaft?

It's weird that the balancer broke off in that area, but in a few words, if all there is left is the snout of the balancer still on the crank, then you're in a world of hurt.
You'll have to remove the front of engine, and use a gear puller (if you can pry the balancer snout far enough forward off of the crank hub to get the fingers of the puller to engage the broken balancer snout.

I figured that was my only option. Pull the timing cover off and use a 3-finger gear puller on the piece still on the crank.

Pulling the timing cover's going to have to happen (may not be a bad time to change timing chain and gears).

If the puller doesn't have anything to grip, you can always weld something onto the remaining portion to which you can attach a slide hammer or puller. If you don't weld you could slip an exhaust clamp over the remaining part (don't over-tighten) to give the 3-jaw something to pull on.

You could also hit it with a cutoff wheel, scoring it almost all the way through, and hit it a couple of times with a chisel (always worked for me on inner bearings).

Or, if you're lucky it may just slide off on its own. Good luck!

Is it possible to pull the timing cover without dropping the oil pan and all of associated work involved with raising the engine and dropping the tranny? With the limited spare time I have that could take weeks

You can remove the forward oil pan bolts and loosen the side bolts just enough to lower the front of the pan.
The pan doesn't have to come completely out to remove the timing cover.
