My Ariel W/NG needs a new sprocket on the gearbox for the secundary chain. After removing the clutch and the primary chain case I can reach this sprocket (see image)



I wondered how to remove this sprocket. It looks like I need to remove the bush were the needle roller cage fits over has to be removed first....
If this is the case, how can I remove this bush/collar?

Thanks...

You have to take the kick start cover off and remove the whole main-shaft.....Clever Idea But it's quite straight forward without removing the box from the frame.

Thanks Ron....I was already afraid that something like this was the answer...

For what it will cost i would put a new bearing and oil seal in while you have the chance i think you can now get the large bearing from A M C classic spares with the modern oil seals fitted but you will still want a conversion kit oil seal for the gearbox.
