Broke timing belt

I broke the timing belt on my 88 TC yesterday so I am trying to put the new one on. It appears that the only way to do that is to remove the bottom pulley from the crankshaft. So, what is the trick to doing that? It doesn't appear that any standard gear / pulley puller will take it off. Is there some special tool required. This system is definitely not a Ford Better Idea. I once replaced a timing belt on a Pontiac Sunbird that I had in about 20 minutes in the KMart parking lot. I was hoping this one would be as simple. NOT!!!!!

Use an air impact to remove the pulley bolt. If no impact available, put a socket on a breaker bar on the bolt, brace the breaker bar on frame, DISABLE THE IGNITION SYSTEM, and crank it over to loosen bolt. Once bolt is off, pulley should just slide off. If it doesnt slide off, a small 2 jaw gear puller with the jaws in the 2 slots will pull it off. I have a tie rod end remover that looks like a small 2 jaw gear puller that works very well for this.

When i did mine, i used a steering wheel puller with two 1/4" bolts bent into an "L" shape. Bend the bolts near the head, and hook that part into the holes on the pulley. i think i got that trick from somebody here...

Not too fun on these cars, but not terribly hard either. Try doing both timing belts on a DOHC 4.6 in a parking lot at 4am, that will have you cursing the ford gods. Doesn't take any special tools for ours. I've also had luck using an impact, and a small 2 arm gear puller on them. I can show you the exact puller I used (Advance Autocraft piece) if you have trouble finding one that will work.

Thanks for the tips. I'll give them a try. Could be that it is just rusted in place. This car has quite a bit of rust in that whole crossmember area.(A good rust free replacement / swap car in need of a paint job is sitting next to it.)I initially tried a large gear puller on the outside of the pulley and that only started to bend the pulley. I decided to soak it with WD40 and let it sit for a couple of days.

Soaking it is good. I also have tapped them with a hammer (gently)all around to vibrate them loose.

WD40 isn't a penetrating lubricant, it's supposed to be a water displacing oil. (hence the WD)

Try PB Blaster or something similar if the WD doesn't help.

I tried your idea using two 5/16" s hooks with the steering wheel puller and all I ended up with was two bent s hooks. Man, this thing is on tight! I am going to have to find a puller similar to a power steering pulley puller that will fit a 2 in. pulley hub.

If your going to use WD-40 use the one that comes with rust penetrator in it that works great

Do you have a small Butane Torch handy? IF so, heat the pulley hub, try to stay away from the crank, you want the heat on the Pulley itself, very hot to the touch, maybe just too hot to touch,and hit it with some Penetrating oil on the crankshaft, not the pulley. Trick is not to get the Crank shaft to hot, warm is OK, and when you spray the penetrating fluid into the Bolt hole on the end of the Crank, the propellant in the can also acts like a coolant on the crank shaft, making it contract a bit faster than the pulley. And the heat in the gap sucks in some of the penetrant! Usually that breaks the gap open a bit. IF you have not got a torch handy, then when you put the pulley on, put tension on the center blot until it looks like your Hooks are bending, and tap the center bolt (the Puller Center bolt) with a hammer. A couple of good smacks and it should pop right off. Good Luck
