Question For The Engine Experts
I pulled my '40 engine out to freshen it up. I'm seeing something I've not seen before, regarding the rear main bearing. The upper half of the bearing (inserted into block) has a groove machined perpenticular to the main oiling groove, extending towards the back of the black. There is a very small hole, which apparently was included to allow oil into this groove.
Anyone ever seen anything like this before, and what would be the purpose? Joe |

That main bearing was made by Ford for heavy clutch use in busses etc. It provided additional lube oil to the rear thrust face. The part number was 81B-6331-whatever undersize letter. The ones I have seen from Ford had a hand scraped area were yours had the groove cut. Also no lube notchs cut in the thrust faces. Hope this helps. Gary |
