232 Starter/Flywheel problems

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   there are two flywheels that bolt onto the pre-1972 AMC sixes, small and large. the small one (Nash lineage, shared with 195.2 and pre-unification sixes) is approx. 12.5" across the teeth. the big one is nearly 14" across the teeth. i know less about these, and i'm fairly sure the ones i have are pre-1972 but i don't really know.
the small one is small! the big one absolutely will not fit inside the early six bell.

	I have torque converters in my garage right now, one originally from a 196 car and another from a 232 car. Both look the same with the exception of the ring gear that is welded on. The 232 ring gear has an extra 1/2" in diameter. The bell housings are also different. Using a 196 ring and bell on a 232 means there is not enough clearance to mount the starter. You could have a bell from a 232 and a T/C from a 196 and have the problem described. The starter teeth would not engage the teeth on the ring gear.

	I have a 1970 Scout with a 232 AMC 3.8L. Do you know what size flywheel would work on it?

	I believe the ring gear would measure 13" across the teeth. At least that is the case with 66 and 67 232's with automatic transmissions. I suppose the manual flywheel would be the same. Edit: If you find one that is only 12 1/2" across it would come from a 196 engine. Edit: From 66 to 67 there was a change in spline count when they went to the electric kick down. More changes up to 1970 are possible. Edited by vinny - Jan/25/2024 at 7:26pm

	I've got photos of all three early six cylinder flywheels, here https://www.ramblerlore.com/AMC/Roadster/transmission/T5research/index.html Scroll down a bit. It's a page filled with notes, not well organized. Some measurements there. I still have these and could measure for you if you want.

	From post #1 you are dealing with an automatic, correct? You have a 232 bell housing which is good. You need to find a 232 torque converter to fit your auto or cut the ring gear off yours and weld on a 232 ring gear. At least that's my take on what I am reading here. If you are dealing with a manual transmission possibly you could change ring gears on the flywheel but I am just guessing on that. Edited by vinny - Jan/26/2024 at 8:59pm

	Hi Vinny. It’s an International Scout with a Manual 3spd T90c transmission soon to be reconnected to the original 232 AMC 3.8L engine. When I got it the engine was removed and the transmission still installed. I am now on the search for everything between the end of the engine’s crankshaft and the bell housing: backing plate, flywheel, clutch disk and clutch cover. I can’t test the engine till I get a new flywheel and want to make sure it’s the correct weight and diameter to fit inside my existing bell housing.
