BSA Lockwasher, crankshaft nut
Lockwasher for the crankshaft nut, found in the crankcase section of the parts books.
PN · 40-0455
This is the lockwasher that sits under the crankshaft nut, part number 40-0455, also listed under the older 40-455 form. It shows up in the crankcase section of the parts books, doing the job every lockwasher does in that spot: keeping the crankshaft nut from working itself loose once it's torqued down.
