keiser31 Posted July 31, 2021 Share Posted July 31, 2021 (edited) Years ago I was in the process of installing the pistons in my 1931 Dodge Brothers DH6 coupe engine and chipped a babbitted rod bearing. It is a small chip about 1/8" at the most in width. I gave up finishing the engine rebuild as I did not want to put a chipped bearing in. Was I wrong in worrying about it? I just had three guys who drive Model A Fords tell me to just finish the engine as the chip would only act as a pool for oil to sit in. I REALLY want to finish my original 1931 coupe that I have had since I was 15, but am worried about the chip. What say you guys about this?

Rusty_OToole Posted July 31, 2021 Share Posted July 31, 2021 Depends what you mean by a "chip" but some high performance engines come with a groove in the middle of the bearing and they work just fine. A photo would help. If it is gouged up you might need to get some bluing and scrape it down. 1 Link to comment Share on other sites More sharing options...
Oldtech Posted July 31, 2021 Share Posted July 31, 2021 We need a picture of the bearing. If the mains were re-babbitted be sure they cut the oil grooves around the center of the bearing. If they are flat the rods won't get enough oil. Link to comment Share on other sites More sharing options...

DFeeney Posted July 31, 2021 Share Posted July 31, 2021 I was worried with the same problem with a Plymouth engine and had the Rod rebabbitted. This was several years ago and a local Babbitt guy did it for $115. as I remember. Link to comment Share on other sites More sharing options...
