NC30 - eccentric hub wear

[lukemillar]

Hey all,

Has anyone seen this before:





I noticed there was play in the sprocket carrier despite the outer nuts still being staked in position. Looks like the carrier has been pressing back onto the adjuster and machining it away. I'm wondering if this is just wear or whether I am missing a spacer/washer? The carrier is mounted directly onto the splines with nothing to separate the two parts. I have a thrust and a flat washer under the nut

Any thoughts?

Thanks
Luke

The spacer washer no 7 that sits on the shaft between the bearing and sprocket carrier is missing i stupidly did same thing a while back couldnt figure out how carrier kept coming loose with hub nut staked had same wear on back of the carrier.

Sweet - makes sense!

If anyone has one handy - could they measure the ID, OD and thickness for me please? The part is discontinued but I can easily make something

Thanks

I've just removed my hub to clean out a couple of decades worth of dirt and grit so I've got easy access-
ID = 40mm, OD = 50mm, thickness = 5mm

Cheers guys. If it comes with the carrier that would be awesome! If not, Thanks for the dimensions Jim

Up till a couple months ago I had a spare swingarm complete I would have given you. The fuckwit that bought all my NC30 spares for nothing might still have it - want me to see if I can contact him or pass a number on?

Luke -

That part has the same dimensions as the rear collar in my chain spacer kit so I have them here ready made if that`s any help - mail me if you want one ricknc30@gmail.com

Cheers,
Rick

Trying to source one locally. I'll see how that pans out but thanks for the offer!

I think I have one in the sprocket carrier I just bought but if not then I'll definitely buy one from you!
