Drive dog nut

["Allyn Richardson" <allynrichardson@cox.net>]

Not sure about the BJ8 but my BN6 had locktabs from the washer between the
nut and the crank bent over the nut to lock it in place. I used a small cold
chisel to pry the tabs up then cut them off. Took me a while to figure out
why a 6 foot cheater bar on the socket wrench would not budge the nut.
