GM Starter / Flywheel fit incorrect (paging eric)

I have not had a chance to dig out my old flywheel yet but this is not making sense... (I'll pick up the original flywheel on the way home) and have it to compare in the AM.

Flywheel isn't gonna just move an inch closer to the enigne ~ Somthing else has gotta be going on.

Almost looks like it is missing one of those flywheel spacers like on the BOP (Buick Pontiac Olds) bellhousing adapter kits or the rear mounted starter take a special flywheel with different ring gear position.

I may have opted to go to the different bellhousing and side mount gear reduction starter...good to see you got it figured out

Now flipping the ring gear makes sense...

Old flywheel looks like the ring gear will install engine side or transmission (with a small dividing ridge in the middle).

New flywheel looks like ring gear will only install engine side. Backside has a hump covering 1/8" of ring gear base.

SO now do I source another flywheel or have this one cut.

i have a side mount bellhousing for a bbc or sbc, and then you use the side mount starter and the FW you have

I think I have a line on a machine shop that can handle cutting the flywheel for rear ring gear. If not I will give you a call and arrange for the side mount bellhousing. (Which starter does that take? Ski DIm only list the top mount for RH Chevy engines)


EDIT: Thanks UK1979 ~ (imissed above) I was typing when you posted.

$60 and 3 hrs later...







Now if I can just get the new FW installed and the trans back inplace before the neighbors complain. Unfortunatly the High school is my front yard and they are right busy this week.

~ Congrats to all those with 2010 Grads

Whitfield who was the original poster probably won't answer your question, he hasn't been logged on for 3 1/2 years or so

But..............here's a quote from another thread by Whitfield with the same pictures of his flywheels. He had his machined

[QUOTE=Whitfield] Resolution was to have the Flywheel machined to accept the ring gear on the transmission side. Cost $60 & only took 3 hrs.



From this: (right is original 84 flywheel with ring gear on trans side)









To This:









Required for this Chevy PCM bellhousing with top mount starter:








Not knowing what your situation is, do you have a 14 inch flywheel with the ring gear on the front and you want it on the back, or do you need a flywheel for your application.

Since a lot of different outfits have flywheels of the right size, if you already have one, probably the only way to really know if you can do what he did is with some measuring or taking it to a machine shop somewhere in your little slice of paradise   

Or you could get the appropriate flywheel from the outfit in the link below. You'll have to read their application list closely to make sure you get the right one or maybe call them to get it right.

Posting more info here explaining just what you have might help too

If we're talking Chevy's here, then it's really a 168 tooth flywheel.   

I'm guessing that you still have the boat together and you're looking for a ring gear to have on hand when you take things apart,

Otherwise if it's already apart you can measure the front and back where the ring gear seats and they should both be the same diameter of about 13 1/4 inches (really 13.268).and take the same 14 inch ring gear. ( It's really 14.096 inches but commonly rounded down to 14 inches)

I've taken a 454 PCM flywheel with the rear mounted gear which is nothing special (the casting number says it fits a lot of automotive 454's) and replaced the ring gear with one for an automotive application with no issues. The same gear fits the automotive applications with the gear on the front with no machining or other issues. The 14 inch ring gear was used on a lot of different sizes of Chevy engines.

Or to put it differently a 168 tooth ring gear like a Pioneer FRG 168s or an ATP ZA-500 should fit your flywheel (unless it's some non stock weirdo type flywheel) with no machining and no issues since you'd be taking one off and replacing it with another in the same location Just a 1 for 1 swap of ring gears. assuming we're talking Chevy's

And .............they're cheap, like under 20 bucks before the dreaded shipping to Aruba

I figure you know how to get stuff shipped to Aruba and who is good to buy from.
