Hi folks, haven't been to the BB much...wife & kids take priority.
> Here's my dilemma: Installed new flywheel on 292...the old one was a PAIN to get off.When I positioned the new one it wouldn't slide on the crank flange easily(just like the old one wouldn't come off easily).I thought,"No problem, just squirt a lil' lubricant on the 3 dowels,and as I snug down on the bolts it will draw the fly wheel onto the crank flange as long as I tighten the bolts evenly,starting at 12 o'clock,then 6,then 9,etc." Did this and it worked great,except.....
> when I felt the bolts were tight to the extent that the back of the flywheel was completely flat against the crank,I looked back there to check, and it appears that as I snugged down the bolts it simultaneously pushed the steel dowels out the rear of the crank flange...one is right up against the back of the block.Guess I shoulda put a shim in there to prevent that but really didn't think that would happen. It's so tight against the block that now I can't spin the flywheel by hand.(No,it is not seized)
>Any ideas on how I can remedy this situation? Thanks in advance for any advice you can offer.

Get the flywheel off then drill and tap a hole in the dowel pin - say 1/4 NC, you can now grab the bolt and pull the dowel pin off the block. Worst case you may need a puller.

Thanks for the reply, i don't have a tap and dye set, but was thinking maybe your idea will work using an easy out.If not, guess I'll have to spend precious budget dollars that were needed on other parts to tap a hole.

you should be able to buy a individual tap like a 1/4 20 for just a buck or two no need to buy the whole set.the easy out might just spin it. you might use a light slide hammer to to grab the bolt and peck it out. good luck, things like this are a pain. hoggyrubber.

Thanks for the help guys...problem corrected and flywheel is installed. i was doing a search on pressure plates to get proper specs for torquing the press plate bolts. Came across an old thread from 7/19/04 titled "New Clutch Not Disengaging".Was scanning thru it and one responder suggested that the clutch disc was installed backward. It reads,"The disc has to go in with the raised portion of hub facing AWAY from flywheel." Is this correct???????? I checked my Haynes manual, and the reference pic shows the opposite...raised portion of hub facing
toward flywheel. I don't want to get my new tranny in,just to end up pulling it again because of an error.Any help?

Most new and reman clutch discs these days are either stamped FLYWHEEL SIDE or have a sticker that says it. Otherwise the flatter of the 2 sides should go against the flywheel and the protruding hub into the pressure plate.

A quick double check on most engines is to place the disc up against the flywheel and try to turn it. If it won't turn smoothly or you feel anything catching on it then it is backwards.
Points of interference are the dampening springs hanging up on the flywheel bolts or the splined hub is up against the crankshaft / pilot bushing. Depending on the counterbore diameter of the flywheel the steel hub ass'y of the clutch may hit the face and the disc itself will not even be able to contact the flywheel face.

Mike, Thanks for the info. I'll have to look into it further next weekend. Work's real busy so I won't have a chance to do the checks you said till then.
God Bless,
