GX140 flywheel is actually same as GX160?

I have a GX140 that became a bogged-down, unfinished pandemic project. Upgrading the flywheel was always a sticking point because I had read that the taper was smaller than a GX160/200. Now I actually have something to put it in and would like to modify it.

My Google-fu has improved since then and I'm finding that a lot of parts references show the same flywheel for GX140s and GX160s. If the 160 flywheel fits a 140 and a 160 flywheel fits the 200, then a 200/clone flywheel should fit the 140, which would solve the problem of availability.

Does anyone have more insight on the parts interchange here? I don't have a 196 clone or anything to get measurements from, only the GX140 and a hemi Predator.

That’s an extremely eureka moment to find similar part numbers across two different engines. It used to be a Gargle-Fu problem indeed, or a lack of Gargle-Fu and lack of published info.

Surely someone knows the answers you seek, might be a lot of forum/Youtube searching and then the dreadful confirmation.

If this helps: I put a 212 ghost flywheel (ghost is based on the hemi head) on a clone 196 and it works fine.

I also confirmed this with AI.
