ok so here it is. lets pretend that this is the setup as terrible as it looks. my paint skills are lacking greatly
A. the bolt you buy that will be longer than youre crank bolt. this fucker could be 6 inches long for this. it doesnt really matter as long as it is longer than the stock crank bolt.
B. the nut that matches the thread of your new install bolt. youre gonna buy this wherever you get the new install bolt.
C. the large washer that you buy with the other stuff
D. the crank pulley
first. piece together the bolt nut and washer.
second. mount the crank pulley on the crank
third. thread the bolt nut and washer assembly through the pulley into the crank
fourth. get two open end wrenches to fit your bolt and nut.
fifth. hold back on the bolt with one wrench while tightening the nut against the pulley with the other
sixth. once the pulley is seated, or close enough to use the replacement crank bolt, remove your contraption and install the new bolt.
seventh. torque everything to spec.
eighth. crack a beer and raise it up to backyard mechanincs
