DOWEL
A hollow locating dowel, PN 70-8009, used on Triumph and BSA unit singles, sold each.
This is a hollow dowel, part number 70-8009, used on Triumph and BSA unit-construction singles. It's a small locating pin, the kind of part that keeps two mating surfaces indexed in place - crankcase halves or similar joints often use dowels like this to hold register while the fasteners do the clamping work.

It's sold individually, so if a job calls for more than one, order accordingly. Cross reference numbers for this same part have shown up as E8009, E11989, and 71-1989 in various parts books, so if you're working from an older list and see one of those, you're looking at the same dowel.
Check your parts book before ordering to make sure this is the right dowel for your application - dowels look similar across many spots on the engine and gearbox, and getting the size wrong means it won't seat properly.
