Re: Lighten an A flywheel
I have a 35# flywheel in my Cabriolet and love it. Made from a model A flywheel. I have seen them as light as 25#.

Re: Lighten an A flywheel
I had mine lightened to 38 lbs. I have seen others say they use some as light as 9 to 12 lbs, but they're aluminum.

Guys, are we not reading what the man's question is? Gord, you can safely remove about 42 pounds from an 'A' flywheel if you use the stock pressure plate, --and about 45 pounds if you convert to a V8 style pressure plate. THAT is about the maximum amount of weight that can safely be removed. The one below was in Pennie's race car for several years and has been 'spooled' many times over 3,000 RPM's. . |

Re: Lighten an A flywheel
A 49-53 Ford V-8 flywheel weights about 29# stock. They may not be drilled for a 9" Long type clutch which you will want. Most were drilled for 10-11" clutches. The starter rework involes reversing the the old style bendix, milling a keyway near the output end of the starter, machining that end plate and using one of those bendix springs you bought at the swap meet that when you got it home it was backwards. Maybe the real trick is providing a "third" starter bushing in the bellhousing to support the shaft end. I have the infor to do this and have done it, so if you are thinking about this I could send it to you. If you decide to go with it you could call me(your nickle from the Maritines) and I will got over it with you.

Re: Lighten an A flywheel
I'm running one in my 30 Coupe; the A flywheel was cut to 35 lbs.; I use a V8 pressure plate as its 4 lbs lighter than an A pressure plate and a much softer unit.
Be sure to have both units balanced; flywheel 1st then bolt up pressure plate and rebalance as a complete unit. Ron |

Re: Lighten an A flywheel
I got a 28 lb flywheel from Dan Price, and Dan swedged on the BB type counterweights and balanced everything. Net gain (loss) of weight was only about 17 lbs, but much much smoother at higher RPMS. Not much noticable change in acceleration or shifting but well worth it.

Re: Lighten an A flywheel
Your answer was not much better than ours. We posted what our flywheels are as an indication of what could be done, because it HAD been done. That, while not answering the question exactly, was useful information. Your answer said "about" in your figure, so it also is not an exact figure. Stop finding fault with people who are trying to help.

AND, with regard to my comment using the word "about", ...is it possible you have no understanding of what is truly involved in machining a stock flywheel? Do you realize that many things factor in such as additional weight removed afterwards during balancing, --or composition of the metal itself affect the exact total weight? Is your Tudor's flywheel exactly 45 lbs, --or is it 44 lbs, 10 ozs, .........or some other number that is "almost" 45 pounds?? It is NOT my intent to be a forum police however I do intend to provide accurate and relevant answers to the question(s), --and just like I expect others to do to me, I will point out errors or misinformation when I see it. If that offends you or anyone else, well I make no appologies in that regard. Last edited by BRENT in 10-uh-C; 09-19-2010 at 08:02 AM. Reason: spelling |

Re: Lighten an A flywheel
I wouldn't recommend whittling anything off a flywheel to someone I didn't know. There is a liability to any recommendation where a spinning mass is involved. We all know it has been done but what is "SAFE" is anyones guess.
Be carefull guys. Also, it's not worth contention. Experimintation is up to the individual to decide. Kerby |
