Pete Phillips Posted October 21, 2022 Share Posted October 21, 2022 I need piston rings, wrist pins, and wrist pin bushings for a 1923 4-cylinder Buick we are working on. My usual sources for engine parts (Egge Machine, Kanter, and Bob's Automobilia) do not carry anything for this engine. Looking for any suggestions and sources...

Fr. Buick Posted October 21, 2022 Share Posted October 21, 2022 I have used wrist pins if you need to go that way. Link to comment Share on other sites More sharing options...
Pete Phillips Posted October 21, 2022 Author Share Posted October 21, 2022 Just found a new set of wrist pins on Ebay. Still need piston rings. 3.37" bore Link to comment Share on other sites More sharing options...
IFDPete Posted October 21, 2022 Share Posted October 21, 2022 Contact Dave at Otto Gas Engine Works in Maryland for piston rings. Many satisfied pre-war Buick owners. Dave has a vast inventory of NOS rings. www.ringspacers.com 3 Link to comment Share on other sites More sharing options...
Ben Bruce aka First Born Posted October 21, 2022 Share Posted October 21, 2022 Might also try Hastings Rings. Ben 1 Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted October 22, 2022 Share Posted October 22, 2022 Pete, Wrist pins are 3/4 x 3 1/8" for 1922-23-24 4 cyl and 1923 6 cyl. If you can't find those above, the next option is D-E 4 cyl, E-H-K 6 cyl. These are also 3/4 x 3 1/8". Also consider buying drilled head aviation bolts from Pegasus for the wrist pin bolt. Original is just a lock washer, and wiring the wrist pin bolt is a better approach. Hugh 3 Link to comment Share on other sites More sharing options...
Mark Shaw Posted October 23, 2022 Share Posted October 23, 2022 Pete, Many (if not most) owner drivers replace the original cast iron pistons with aluminum pistons. This reduces the rotational weight of the engine and increases the original engine power by about 10%. Modern rings and wrist pins also reduce friction to increase power while reducing wear. 2 1 Link to comment Share on other sites More sharing options...
