Selim Posted October 29, 2020 Share Posted October 29, 2020 Having problems starting my 1949 super . Sometimes it does this, other times not! I think I need to buy flying wheel? What do u think Sometimes it does that 6-10 times till it works https://youtu.be/b3rKk62Nia0 Link to comment Share on other sites More sharing options...
Dan O Posted October 30, 2020 Share Posted October 30, 2020 Sounds like the flywheel is not engaging with the gear on the starter. It is probably a broken tooth on the starter gear - at least that's what I would check first. You can also inspect the teeth on the flywheel when you pull the starterto see if they are broken - they will be right there I would think.

Do I have to get a new one, or could it be fixed? And if I have to buy a new one, where to get it? Link to comment Share on other sites More sharing options...
Dan O Posted November 16, 2020 Share Posted November 16, 2020 Selim - pull the starter out and look in the hole where the starter goes in to meet the flywheel - do you see broken teeth on the flywheel? If not, how about the starter gear teeth? Starter is probably the problem - it may be broken and is easiest to fix. I have a spare flywheel from a '49 Buick 320 engine if you need one.

I have a spare flywheel from a '49 Buick 320 engine if you need one. starter is new, we can detect broken teeth in the flywheel ring gear. that is what i believe i need! mechanic told me we can turn the sides of the flywheel ring gear (flip it) in order to get the intact side of the ring interacting with starter! would that work?

Dan O Posted November 18, 2020 Share Posted November 18, 2020 Interesting solution. I guess it would work for awhile if the teeth were just chipped. But I would assume they will break again. To replace the flywheel you need to pull the engine so I'd replace the whole flywheel rather than risk pulling the motor again. What motor do you have 320 from the Roadmaster?

Selim Posted November 19, 2020 Author Share Posted November 19, 2020 fly wheel ring gear broken teeth. it is a super 1949 ser 50 engine 248 original engine do i have to change the whole flywheel? or just the flywheel ring gear. is that it at bob's? any clue for a cheaper solution? thanks https://bobsautomobilia.com/engine/flywheel-ring-gear-1939-52-s.40-50-.-frg-393/ Link to comment Share on other sites More sharing options...
Dan O Posted November 19, 2020 Share Posted November 19, 2020 That looks like it would work rather than the whole flywheel. I am no motor mechanic so I could not say. Look at your service manual but you will need to separate the transmission from the engine at minimum to install the ring. Not sure if you need to pull the motor or just the transmission. Best of luck! Link to comment Share on other sites More sharing options...
critterpainter Posted November 19, 2020 Share Posted November 19, 2020 Does the car have a Dynaflow automatic transmission or a manual transmission? If the car has a manual transmission, Bobs Automobilia should have a ring gear. 805-434-2963 Link to comment Share on other sites More sharing options...

critterpainter Posted November 19, 2020 Share Posted November 19, 2020 Yes that should be the correct one, but to be sure give them a call. Mention "Bill" to them. I worked there many years and they are good guys. Link to comment Share on other sites More sharing options...
Selim Posted November 30, 2020 Author Share Posted November 30, 2020 Here r pics flying wheel broken could it be fixed ? Mechanic looking at it now Link to comment Share on other sites More sharing options...
critterpainter Posted November 30, 2020 Share Posted November 30, 2020 To my understanding this flexplate is not available. You will need to find a parts car with a Dynaflow. Flex plate interchanges between Special and Super but Roadmonster is unique. Link to comment Share on other sites More sharing options...
Selim Posted November 30, 2020 Author Share Posted November 30, 2020 Flex plate indeed not available. For the time being , can this one like shown in pics be fixed? Link to comment Share on other sites More sharing options...
critterpainter Posted November 30, 2020 Share Posted November 30, 2020 I don't know what years interchange on the flexplate. If you belong to the Buick Club of America you can put a free part needed ad in the monthy magazine. Thats an interesting failure. Perhaps it can be patched, but I would look hard for a used one first. Link to comment Share on other sites More sharing options...
Dan O Posted December 3, 2020 Share Posted December 3, 2020 Selim - here are two flywheels for 1949 Buicks on eBay now. One looks like a fit but the second one needs a better description as to what it fits I think: https://www.ebay.com/itm/1948-1949-1950-1951-1952-Buick-Flywheel-Ring-Gear-Dynaflow-50-70-series/233801684150?hash=item366faa94b6:g:pZoAAOSw2sRfuZiR https://www.ebay.com/itm/1940-1941-1946-1947-1948-1949-1950-1951-1952-Buick-Flywheel-Ring-Gear-Excellent/233803028320?hash=item366fbf1760:g:NRoAAOSw0Ptfuv3h Link to comment Share on other sites More sharing options...
critterpainter Posted December 3, 2020 Share Posted December 3, 2020 Ask the seller of the upper one for the O/D of his and for the tooth count on the ring gear. 40 and 50 series (special and super) should interchange but 70 series (roadmaster) should be a larger diameter. If it matches yours its a good deal! Lower one is a Flywheel, not a flexplate. Not for Dynaflow. Link to comment Share on other sites More sharing options...

critterpainter Posted December 3, 2020 Share Posted December 3, 2020 You will have to measure the outside diameter and count the number of teeth on YOUR flexplate and compare it to the one for sale. That information fell out of my head ages ago. Link to comment Share on other sites More sharing options...

critterpainter Posted December 3, 2020 Share Posted December 3, 2020 The first Ebay listing has been corrected. It is correct for a 40 and 50 series (Special and Super) It would be wise to have it incase yours breaks again. they are hard to find. Link to comment Share on other sites More sharing options...
