Crank dowel pins for M/t flywheel

[ericjon262]

does the 3x00 crank require a dowel pin to correctly locate the flywheel on the crank. I mocked up my flywheel on my crank, and the flywheel is loose on the crank, not flange to flange loose, but rotationaly (I think I made that word up...) loose, like the bolts aren't big enough for the holes...

Thanks-

i used a flywheel for a 3.1 5 speed Cavalier on my 3500, never had any problems. Just stuck it on there and torqued it down with red loctite on the bolts.


make sure you use the longer bolts that match the flywheel and not the short flexplate bolts. That's a quick way to jack up your crank.

I might have my buddy at the machine shop machine me some sleeves, I don't feel comfortable with the amount of play the flywheel has, non of the flexplates on my many auto trans cars had that much play...

Dave is right. As long as the bolt holes line up it will be fine. The FW/FP only can fit on only one way and there is play in the bolts/holes but the center hub holds it true to crank center line.

Since 1986 the cranks are internally balanced. The FW/FP is neutrally balanced and doesn't need to have a specific rotational location.

the play is the part that makes me nervous, to me, it seems as though they should hold the flywheel snug...
