The Stovebolt Site Forums The Shop Area Engine Shop 216 Flywheels

Are all 216 flywheels the same? And would there be a different clutch size for a truck engine than a car engine. If all the flywheels are the same, will they accept different clutches?

I am trying to get ahead of the game on my engine replacement. Usually a bad idea for me.

There were at least 2 different size clutch discs used with 216 engines.

The flywheel used one clutch size.

A car could be ordered with a 216 and a larger truck-type flywheel/clutch-disc (same flywheels and clutch discs - cars and trucks).

If I am wrong, we'll hear about it.

Here is info for 1946 and 1952 (as examples):

1937-39 use 4 mounting bolts.
1940-41 use 6, 3/8" mounting bolts.
1942 and later use 6, 7/16" mounting bolts, and smaller center pilot hole.

I want to say a 1 ton flywheel/ clutch had a different bolt pattern (flywheel to pressure plate) than 1/2 ton. I used a 216 flywheel from a 1 ton on my 235 (so I could keep stomp start; 139 vs 168 tooth, not 1 vs 1/2 ton) that I put in my '49 1/2 ton and I think I had to use a matching 1 ton clutch set. I believe the 1 ton flywheel was thicker, too.

49Neo,

That is correct for all/many years (clutch sizes).
That is shown at the links for truck clutches that I posted above.
It is shown here for 1949 trucks.


"I believe the 1 ton flywheel was thicker, too."

It would be interesting to know if the thickness of the flywheel is different. That is possible as far as installation is concerned.
