OK have all the parts after the exploding fan clutch (see my previous posts).

Is there anyone out there in MA that has the tool for counterholding the pulley that they would rent out?
Car is a 92 400E (M119 engine)

Removed the fan radiator and then the fan shroud (yea I know the order is backwards but the inserts in the shroud spin so I was able to do it this way and not destroy 1/2 the shroud. Anyway now the bolt doesnt want to come out easily. I can see the serpentine velt tensioner move when I try to turn the bolt.

There is not enough room to get a normal size open end wrench in to the four bolts that hold the pulley in place - I suppose I could grind down a wrench. Also thought of removing the serpentine belt and try a strap wrench around the pulley.

Any help? I did a search, and I have cleaned out the allen fitting with a paperclip. Looks like about 1/4 inch if engagement on the allen fitting.

So anyone local with a tool to rent, I'm in MA near Worcester.

Thanks
Paul
