[Healeys] Locking Crank

[Bob Spidell]

After trying all the other 'techniques'--don't forget to undo the tie 
rod on the back of the O/D--I bought a 3/4" air impact wrench from 
Harbor Freight (the socket was almost as much as the wrench). It barely 
fit between the chassis crosspiece, but spun the nut right off.

An 'extravagant' purchase to be sure, but I also have a large, 8-sided 
rear hub socket with a 3/4 inch female 'socket.' The hub nut has an 
official torque setting of 'tighten until all the snot has come out,' 
and the wrench accomplishes it.
