Sprocket Needed

[Deleted member 4366]

I broke the sprocket on my GNG motor, so I need a replacement. I've done a lot of searching, but got nowhere. Can someone help? It's the same as the one on a Currie, Izip, Ezip and many electric scooters: 9 teeth, 11mm hole and 5mm key slot.

If anybody has a dead scooter or motor that they don't want, could you look to see if it has a 9 tooth sprocket on it, or if you have a Currie/Izip drive, I can swap your sprocket for a 13T one which makes it go a lot faster.

Alternatively, does anybody know someone that stocks these. The USA suppliers all want >$50 shipping and GNG only offers 13T as a replacement, which has mucked up the cadence.

I will ask around just in case I can help, best I found on google are on mowers and chainsaws but would need mods to fit.

Might do but you will need someone the machine it to fit your shaft:

Youi could try Tony Castles at Electrodrive, the Currie kit agents, he often has various spares. He can be difficult to get hold of though and is often very slow to answer mails:

My mate will make 2 collars, press and weld them to the side bosses if you want to give it a try (no charge)

I shall look on the Izip via Lento I have in a bit and let you know if its 9T. If so will do a swap.

 

[fatts]

Yes its 9T so I shall pm you my address and you can do like wise with your address I wont have time to take off till tomorrow evening. I am off out in 10 mins for the day.
Here is a couple of pics.
Do you know if the chain on those is half by one eighth or three thirty seconds? As I shall need to replace with a bit most likely

That's brilliant Fatts. I think you need a two or three legged puller to get them off. Just make sure it looks like this - but not broken. I'm not sure of the chain size, but mine's normal single speed chain whatever that is.

 

[fatts]

Ah its a one eight chain then. Right I will have to hunt down puller once nut is off.

Here's a thread about the conversion from 9 tooth to 13 tooth:

[Deleted member 4366]

Excellent. I'll pull mine off then too.

No joy shifting with puller, must be bent input shaft, but a friend has put a message up for me on a trade only bike forum for one.
