1939_Buick Posted September 25, 2020 Share Posted September 25, 2020 (edited) Other bearing threads---> Not your part number-- https://www.abf.store/s/en/bearings/909702-NEW-DEPARTURE/362602 Do you have the dimensions? Then take it to an industrial bearing supplier. Do not say its a car part: its just a bearing Not applicable to 1920-1930's https://www.ahrinternational.com/HYATT-BALL-BEARINGS_nomenclature.shtml Edited September 25, 2020 by 1939_Buick added https://forums.aaca.org/topic/227547-1924-buick-front-wheel-bearings/ (see edit history) Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted September 25, 2020 Share Posted September 25, 2020 When I was going thru the front axle for my 1925-25, I found that the outer races required only a single adapter on the bearing race to make a modern roller bearing fit. For the inner bearing, I could not find a good replacement and I felt that I would need to make an adapter for both the inner cone and the outer race. What complicated matters was the oil seal, as this is part of the bearing and that would need to be designed into the adapter. Not a big job to do this, but something that would need to be done. I just happened to be able to swap enough parts that I did not have to replace the inner bearings. 909703 fits all smaller Buicks 1922 thru 1928 so you have a wide range if you are looking for used bearings. I also remember someone in the Chez Republic claiming to have old obsolete bearings, but this was a scam. Hugh Link to comment Share on other sites More sharing options...
1939_Buick Posted September 25, 2020 Share Posted September 25, 2020 (edited) Download ND_1939_OCR.pdf. Look at pages 92-95 and on. Has dimensions. Is the April 1939 (13th edition) of the New Departure Handbook. New Departure was a GM subsidiary- GM brand. Take those dimensions to an industrial bearing supplier (not a car parts shop). The complete assembly part number 909003 may or may not be available or have an equivalent; Timken etc (I currently do not access to all my bearing -interchange books) Untitled - Vintage Machinery Wiki wiki.vintagemachinery.org › GetFile › ND_1939_OCR Untitled - Vintage Machinery Wiki Edit More digging. Timken use the same part numbers Edit 2 Another bearing catalogue to download These can be very useful https://archive.org/details/UnitedMotorServiceBallAndRollerBearingDataCatalog2056thEdition1920Through1930OCR88Pages Edited September 25, 2020 by 1939_Buick (see edit history) 1 Link to comment Share on other sites More sharing options...
