Flywheel for motor swap

[wiboater 19]

I pulled the Bellhousing off of a 1938 Dodge RC 218 engine, 25 inch block. The bellhousing is different on the transmission side They gave more room for the clutch plate. I Took some pictures , will try and post them later. You are probably right about the flywheels though too. The one that I had in the 36 I had replaced a while back. The one that came out of the truck was thicker on the block side . I'll have to measure them tomorrow. Anyway I should be ok now with the 218 bellhousing having more room inside at the top.  

  I did just realize though I would have to use a 37 or 38 transmission though because the 36 has the shifter moved forward. It sits on part of the bellhousing. I'm trying to find a different flywheel now.

Wanted to add something

anyone know the dimensions on the 230 Ci. flywheel ? Thickness where it bolts on. and from there to the face. Just thinking about maybe taking a 218 flywheel in and having a machine shop take some material off to make it a 230 flywheel.

I called the guy I got the engine from and he found a flywheel for a 230 he had. It was thinner and now the clutch fits fine. Transmission is back in etc. Thanks for the info about the clutch differences.

Good to hear that you have it together.

Anyone know the reason the holes on the flywheel are drilled so it will only fit on in one position? Just curious. I can see if it were balanced on the engine at the factory but if you replaced one it would be different.

one hole is offset probably so the flywheel isn't put on backwards

[wiboater 19]

wouldn't it still fit backwards though?

Not without a blowtorch and a BFH

 

Rather than go into the geometry, as an exercise simply trace and cut out the flywheel holes on paper...then align the paper holes to the crankshaft, then flip the paper over to see the difference...

My guess:  The parts are balanced separately when new but with a 'dummy' standard flywheel or crank attached.  The hole offset assures the real part is assembled as the dummy was when balanced.

if you put it on backwards the engine will turn the wrong way!  🤣

So this is what I’m going to try on my a Desoto; going to pick up Plymouth running gear this weekend to use the trans on my 237.
