Crank help. May be simple?

<< < (2/3) > >>

thebigdog:
I am not sure what your saying here.

Takagi, sugino and nearly all 1 bit crank stuff should all interchange. Are you saying the locating pin on the crank arm is slopping about in the hole on the spider?
Is there loads of slop? The hole should be a lttle bigger to let the locating bit in and then you tighten the bearing cup thing up against it and it should hold it tight.

dan-dare:
Twill be fine with the sugino, mr.munners.

Yes the hole on the spider is slightly bigger, but once nipped up it'll be ok.

You are only pedalling forwards, so it will sit against the pin on the crank. :daumenhoch:

pickle:
i got the impression it was the main hole that the crank arm goes through that's bigger?  not the small hole that stops the spider from spinning??

daz bmx it!:
I would go with the Takagi,thats what mongoose did bitd :daumenhoch: you'll need the different chainwheel of course :daumenhoch:

SteveG:
I think they are all a bit of a loose fit. I always had a bit of movement on mine as I had a coaster brake but it should be ok once the bearing cup is tight up against it.
