Subject: [FlyRotary] Re: flex plate
I
ran a Ross drive for 200 hours before switching to Tracy's, maybe I can help.
My Ross came with an aluminum wheel with a ring gear for starting. It sounds
like you may be missing this part. This Ross wheel bolted to a counterweight
from an automatic, and the triangular spring "dampener" (made from a clutch
plate) attached to the aluminum Ross wheel.
Tracy's unit uses the same counterweight, but uses the stock automatic
flex plate, the lightweight 3 pound unit.
The
manual transmission cars used a heavy flywheel with ring gear for starting and
this had the counterweight built in.
The
automatic transmission cars used a separate flex plate and a separate
counterweight, maybe 7 inches diameter and 10 pounds if I recall. The
torque converter bolted to the flex plate and made up the rotating mass for
the flywheel effect, that why the flex plate can be so
light.
If
you have the heavy manual flywheel, I think you will have to remove it with
the big nut and install the automatic counterweight and a Ross flywheel. You
don't need that big heavy flywheel anyway.
Hope
this helps

Thanks, Ed. I have to admit that
I am still not certain that I understand everything I need to know about
the flex plates, etc.
Hi Paul,
Maybe I'm missing something, but why do you need to
know anything about flex plates for your engine swap? Aren't you
going to install the Ross drive on the new engine? If so,
wouldn't you also move the Ross drive plate (with the
springs) and or flex plate at the same time? I just don't
see why you need anything new.

Hey, Rusty....yes, I would install the Ross drive
on the new engine, along with the Ross drive plate that has the
springs. I just thought if I had the proper flex plate, it would be
an easier engine swap if I just have to remove and reinstall that
triangular looking plate with the springs. I understand that is the
drive plate. What the heck is the flex plate....are we talking about
the cast iron flywheel? That is harder to exchange, because of that
large 2 1/8" nut . If I just have to remove and reinstall the
triangular Ross drive plate that has the springs, and it will bolt onto
the flywheel of the standard transmission engine, then I am all set.
