A couple questions: What are the nominal standard dimensions of these Lycoming main bearings—width and thickness or OD and ID. I really need the width so I can check the loads this size bearing can sustain. The bearings I’m interested in are marked number 7 in the drawing. The part number that I have for them is 18D26096. I think they are for the 2.625” diameter crank. Also, are these bearings sold as individual halves? Or are they like car bearings where one bearing includes both halves? Price is around $30 but I don’t know if that’s for one or both halves.

Dan? Are you there?

Thanks,
Rob
