Chevy flywheels

[Jordan Baker]

Any thoughts on putting the 6v flywheel on my crank? It will have the gap between the crank flange and the flywheel hole. I’d also have to enlarge the 6 mounting holes?

I was faced with this back in the mid 90s when I did a truck for the Saskatchewan military museum. I removed the ring gear from the flywheels, turned down the 12 volt flywheel, and installed the smaller gear onto that flywheel. Worked, but since the lathe I was using was a brake lathe, I am not sure I got the balance completely right. I would suggest getting a real lathe to do the turning on, and then get the flywheel balanced afterwards.

Jordan,

Having worked in an automotive and heavy duty machine shop I have done ring gears many times.

It isn't rocket science, more like good old fashioned bull work with some accuracy and some speed

Having one piece of ply thick enough to exceed the thickness of the ring gear works best.

Heat the ring gear using a neutral flame on an oxyacetylene torch with a cutting tip and heat it all the way around in a circular motion.

Grab it quickly with gloves and set it on top of the ply and using oak or aluminum or brass drifts hit the ring gear a good solid whack in once place and move around the ring gear swiftly, if you have heated it good and you move fast it will move a fraction as you go. Hopefully you hit your drift with a good size hammer and with purpose.

To install on the other one you will need to heat it up all around again and fast and using proprietary tools grip it and drop it on and again if required drift it back into place as it cools.

I guess I am being glib as we did them a few times a week.

There are plenty of youtube university videos to aid you.

Have fun

Hi Jordan, I think that you could have a bushing made to take up the space on the crankshaft. Use lock tight bearing mount to hold it in place, and drill out your flywheel out to fit the larger bolts. I don’t see you having any problems doing it this way.
