Can somebody answer a crank pulley question?

[Troublemaker]

I can't figure out how to upload a picture from my phone, so bare with me. I have a few different size under drive pulleys that I wanted to try. Are the 6 bolts all that should be holding it on or is the big one in the middle part of it also? I stayed in place after the six bolts were removed, and may just be seized and need a little prying, but I didn't want to pry if that middle one is holding it. It looks like the pulley should slip right off.

It must just be stuck to its mating surface. Tap it withe a solid piece of pipe or somthing similar around the bolts you already took out. Should break loose fairly easy. The large center bolt is for the damper only. Good luck.

I got impatient and pulled, it came off. Now to figure out what size belt I need, stock is too long and the replacement I bought with it was too short.

Run a bit of string around all the pulleys, allow for the belt tensioner pulley ( put it under load ) then mark the string at the join, and measure length

That's what I did

Use a tailors tape to measure it. Simply wrap it around all the pulleys as if it were a belt. Or string..

LOL, Fats, your fingers were faster than mine!!!

As far as the belt length goes, I stopped being lazy and just did the entire job. The set I purchased came with what I will call and overdrive water pump pulley(smaller). I suspect it's to keep the water pump moving along at its normal speed while slowing down all the other accessories. I was avoiding it as it meant pulling the airbox and aluminum brace out, but it dawned on me the reason the belt wouldn't fit is the stock WP pulley was just too large. I bit the bullet and did the job right. Motor monts, trans mount and underdrive pulleys all completed this weekend. And it really only took 4 times as long as it should, I'm improving.
