Cast Iron Posted February 20, 2017 Share Posted February 20, 2017 (edited) Hi all - I have a 1954 Pontiac straight eight motor that is missing a flywheel, bellhousing and clutch. Does anyone have a flywheel they could spare? Or, do you know of a flywheel from another engine that interchanges or can be modified to work? Perhaps someone could tell me the flywheel diameter and number of teeth on the ring gear? Step one is to get this motor running for a static display.

Printed magazine? If so, I have no money to subscribe which is why I don't get Hemmings. Very fixed income so have to be careful what I spend money on.

Guest Posted February 22, 2017 Share Posted February 22, 2017 Smoke Signals is the club magazine of Pontiac Oakland Club International (POCI). The 239 cu in engine was the same basic castings from 1941 until 1954. So I would imagine that the flywheels would be the same. Maybe you should just get a parts book and check.

Golly, if I had a parts book I would have looked it up. I figured from the name of this forum that folks here would know and possibly even have extra parts they don't need. Or that someone would have a motor apart who could give me the outside diameter and number of teeth on the ring gear - information not usually found in parts books. Hopefully someone will chime in. I figure that if I can't find a stock flywheel that I can adapt one from some other engine. BVTW, thank you for the info on Smoke Signals. I had not known of that magazine or of the POCI.

Guest Posted February 22, 2017 Share Posted February 22, 2017 You are welcome. I can't look it up for you because all my parts books, shop manuals etc. are pre-war (specifically 1926-1934. I will ask my friend if he can help. Link to comment Share on other sites More sharing options...

pont35cpe Posted March 14, 2017 Share Posted March 14, 2017 Cast Iron, I have a `41 Pontiac six cylinder engine, but not sure if the 6cyl and 8cyl flywheels are the same. Maybe someone could advise. If so I`ll see if I can get it apart. Tom Link to comment Share on other sites More sharing options...

I would be very appreciative if you have a flywheel and, for that matter, if possible the bellhousing, clutch and release bearing as well.
