Re: Question For The Engine Experts

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.
