Crank fitting

(1/2) > >>

erniemadden:
after copping the hump with my flights because I did not have the right allen keys, I turned from old to new skool and tried to bung some cranks on my rider, but I can't get this new skool crank to run true.
So I have a primo crank, 4 washers and a profile chainring.
1st thing are they compatible?
2nd how the F*** do they go together.
I have tried washers in between chainring and pedal arm no washers and washers on the otherside of the pedal arm.
So what am I missing?




oh if anyone knows the size of the allen keys for the flights it may be helpful  ;)

HEYWOOD BMX:
 :) Not sure a Profile sprocket (usually have a 22mm centrehole without tophat washer) will fit onto a Primo axle,also 22mm...

erniemadden:
thanks for the info, but you will have to excuse my ignorance.
what is a top hat washer and if the chain will does not fit do you reccomend a Primo chain wheel?

Cheers....Steve

HEYWOOD BMX:
  This could take a while! Have a look at this,might be of some help? Think this shows a Profile type 48 spline crank & a Euro bottom bracket but the basic principles are the same.

thanks for the link that makes things clearer.   :daumenhoch:
Choosing a suitable chainring is a mindfield.
Any suggestions?
