1990 Aerostar Problem
I have a 1990 Aerostar with the 3.0 engine, 5-speed transmission, RWD, etc...
The engine have jumped time on the timing chain, and I'm in the process of removing this. I have encountered a majr snag. I cannot get one of the bolts holding the crank pulley to the damper off. I do not know if it was general practice at Ford during initial assembly, or anything, but these four bolts had lock-tite on them, and also seemed to have been over-torqued. Most likely some other service performed in the past.
Question is, does anyone know of any good tricks for removing these bolts when theyre in there tight like this? I'm planning on trying the old heat it and turn it method, using a butane torch, and see if that works...but are there any other ideas?
I need to tget this van back on the road, as it's my family's primary people mover...

A lot depends on your resources, of course. An impact wrench might do the trick. I think you idea of heating the srrounding area is a good one. Did you you hit the bolts good with some penetrating oil?

yep...liquid wrench is about the only one widely available here...and the only one i have in the garage...
an impact is an idea we've toyed with, also, but i don't have an aircompressor, so pnumatics are out of the question...and i don't have the cash for an electric impact right now...

Don't know if it would work on the pulley-to-damper bolts, but I used a "starter bump" method to get the crank bolt off the engine in my SHO. I put an impact socket on the bolt head and attached a strong breaker bar (not a ratchet), making sure the bar was lodged completely against a subframe member. I disconnected the harness connector from the coilpack so the engine wouldn't start, then I engaged the starter just a touch, using the torque of the motor against the breaker bar and subframe member to loosen up the bolt. Worked well in that situation.

Put a pipe wrench on the side of the pully and lodge it on the P/S mount or subframe. Get a ratchet and a breaker bar and pull like hell. Have done this 3 times with great success. The pipe wrench will scratch the pully up a little but it is not bad. If you want, you can put a rag between the wrench and the pully. You would think that it would bend the pully, but it will not. Good luck.
