NC24 rear sprocket replacement - Advice please? Smart ppl!

[Manticorp]

Okay so, here's the deal

I bought new sprockets and chain, and, after many a problem coming up, i finally got the old ones off

however

the new sprocket doesn't have the required cut-outs to allow it to pass over the bolts that attach it to the cushdrive

My dilema is - I don't wanna have to take the whole hub off, basically, just to get the sprocket on, as it means buying a new nut, a 36mm drive and also finding a suitable stand (probably an abba stand = expensive!)

I've contemplated just cutting the new sprocket to fit - but I'm hesitant to do so as it will probably end up unbalanced and weak

The attached photos may illustrate this a bit better than my words

Mechanically minded people may see a simple solution here, ar maybe just someone smarter than me :D


This is the cushdrive/hub, the offending nuts outlined in green


This is the new and old sprockets


and the old on top of the new, to show where the cutouts on the original are

I'll bet you have tried everything I can think of...that sucks man!

can you put it on from behind - take the rear wheel off?

I am liking your pics...if you had a klaxon sound with it i would be even better.
Sorry dude, I got no idea... Don't go chopping the sprocket though - bad call.

Harry if you get stuck and need a abba stand i have one you can borrow.

Should have read this post before i came and picked the paddock stand up

Mmmmm

Well, that's kinda a last resort, as i say i don't have a stand for it, i do believe you replied to my thread before regarding spindle sizes etc...so I've just had to sell the stand i bought, I may be able to improvise though...

Haha well I'm glad you said that, cos i might have just gone and sawn a couple of chunks out of it through pure frustration!

Failing this, I may have to put the old sprocket back on for a while until i can get an abba stand or something....but that means doing the whole bloody job all over again...and also wearing out the new chain faster than is needed...

Thanks for your quick response, I'll try and keep you posted, and maybe put up a warning thread for anyone who's going to attempt to change their sprockets on their NC24's!

p.s. maybe some club dance music would be better? :D

Ah, is that Tony??

That's very kind of you! If I can think of no other way, I might just take you up on that offer! Certainly would make removing the rear wheel a much easier job :D

I wouldn't wanna trouble you again by making you come over here though, would coming and picking it up in the evening tomorrow, or later tonight even, be alright? :)

[Drunkn Munky]

yep thats me :)

im off out in a bit and will be back about 8 ish, your welcome to pick it up then or tomorrow

[Manticorp]

Okay, I'm supposed to be taking the gf out tonight anyway as valentines day steals me away from my bike, but I'll give you a ring later or something!

Thanks again, and if you ever need anything don't hesitate to ask, hope the paddock stand serves you well :)

no probs. pm sent

There not the right sprockets?

Whered you get them from.

I got them from WEMoto, the chain and front sprocket are okay, I think this is just a kinda of 'universal fit' type thing, if you see what I mean? Maybe it would be easier to buy a decent sprocket then? :S

Any idea where I can find a good one?
