BSA Bearing, crankshaft drive-side (Hoffman 325)
Hoffman 325 drive-side crankshaft main bearing, part number 24-0732.
24-0732 is the drive-side main bearing for the crankshaft, listed in the catalog under crankcase and cylinder-and-crankshaft figures. It's a Hoffman 325 unit, which tells you the bearing type and size range the factory specified for this position, and it's the bearing that carries the crank on the side where the drive-side flywheel and timing gear live.

This one's straightforward parts-counter stock: a specific bearing number tied to a specific bore in the crankcase casting, not something you want to substitute on a guess. If you're rebuilding a bottom end and pulling the old bearing, check the housing bore and crank journal against what you've got before you order, since the catalog data here doesn't spell out which exact model this crankcase came off.
Also shows up under the alternate form 24-732 in older listings, same physical part. Appears across catalog entries from 1969 to 1970, so it's worth confirming against your crankcase casting or parts book rather than going strictly by year.
