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. =20 Hope this helps =20 Chuck Dunlap RV6 13B cruising past 400 hours =20 ----- Original Message -----=20 From: Russell Duffy=20 To: Rotary motors in aircraft =20 Sent: Sunday, January 23, 2005 10:38 AM Subject: [FlyRotary] Re: flex plate 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. =20 =20 Hi Paul, =20 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. =20 =20 Rusty =20 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.
