Does anyone out there happen to have a comprehensive part number cross-reference for Lycomings? If you go to the most current parts catalog for the O-360's, you'll find drawing sand tables that have been around since the 50's (or earlier), and the part numbers doesn't correspond to anything actually available from the various suppliers today. For instance, a crankshaft for an O-360-A1A is listed as a 74966. Through a lot of digging, I have found that the modern part number for that is 13B47120 (or maybe its a 13B27120 - its no clear which superseded the other...).
I was on the phone to Aircraft Specialties, who can for sure send you the right parts, but even that parts guy said that he just had some spreadsheets (which he didn't offer to share) to get customers the correct parts.
Unless I missed it in the stack of Lycoming Service Letters, Bulletins, and Manuals, I don't think they gave us such a table at the Lycoming school. It sure would be handy to have when shopping for parts!
