Dowels like this keep mating crankcase surfaces or fitted components aligned to each other so they seat the same way every time they're taken apart and put back together. Because it's hollow, it likely also gives clearance for a fastener or a locating pin passing through, but our records don't spell out the exact arrangement.
The catalog ties this part to crankcase work across a couple of appearances in the early 1960s parts books. If you're sourcing one for a rebuild, check the fit against your actual cases before ordering, since our listing doesn't go into further detail on dimensions.
