Thread: Flex Plate/ Fly wheel

Tweet

I'm a rookie so I apologize for my ignorance but is the fly wheel the same thing as the flex plate. If not then what is the flex plate. I am ready to install my flywheel on to my 350 and was wondering if there is anything that goes in between it and the the crank shaft. I am planning on putting in a turbo 350 or a 700r4. I have a 65 chevy pickup.
Thanks

Clutch cars have a flywheel

Automatics have a flex plate

Both have the ring gear teeth for the starter.

oh so I might have the wrong thing then. Is the flywheel thinner where it bolts to the crankshaft because the bolts I have seem to be too long and are bottoming out. So the torque converter bolts to the flex plate right?

On the crankshaft flange, the bolt pattern for a flywheel and a flex plate are the same. The manual transmission crankshaft must have a pilot bearing in the center hole of the crank.... on an automatic, it doesnt use the pilot bearing so it doesnt matter. The center flange of a flex plate is thinner than a flywheel. Get new bolts from either the Chev dealer OR a good speed shop. Torque the bolts to the listed spec.

Yes, the converter bolts to the flex plate. Use new Chevy bolts here also.....never use hardware store bolts in either locaton. The bolts are less than a buck each at the Chevy house.

Always run the dust cover on the transmission to cover the flywheel or flexplate at the bottom.
