what about if you don't have one?

I was thinking the same thing last night, getting the crank arms on is a b'stard, god knows how I am gonna get the mo'fos off!  :LolLolLolLol:

Sanmarcopizza:
Getting profiles off is brutal, unless they are worn a bit and slide off easy. I would recommend the use of the correct tool. Basically all it is a big nut with a shoulder that sits against the end of the spindle. You then make at it like a madman with a hammer and bash it until you have knocked the spindle through the arm. You could use an appropriate sized drift, byt there is a chance you will flatten the end of the spindle and not be able to get a bolt in again. I think there are some PDF manuals on the profile racing web site.

BrianP:
if you don't have the profile tool and are having diffs beating the spindle through to get the arms off, if you use a washer small enough to drop through the crank arm splined hole but big enough to cover as much of the end of the spindle as possible (to protect it and spread the loads) and set this onto the spindle, then tighten down an allen head bolt of the same thread as the regular hex head spindle bolts, this gives a good solid base to put a bit of solid bar against to drive the spindle thro.
(use an allen head bolt / machine screw cos it's smaller than a hex head and will definitely clear the crank arm splined hole on the way through)

BUT

u gotta make sure that the allen head bolt is proper tight (and stays tight!), so u don't feck the threads in the spindle.

one other thing, spread some grease on the spindle splines b4 assembly. really helps next time u dismantle....

I put loads of grease on the splines of the crank arm I have fitted. So hopefully, fingers crossed...
