I have just noticed that the external circlip is missing from the end of the gear selector shaft inside the selector box. The internal circlip is in place behind the selector arm.
When I try to push the arm further on, to fit the external circlip, the splined shaft moves inwards too.
I thought the arm should just pull off, so that I could see what is behind it, but it will not easily come off the splines. Should I try to lever it off?
Any ideas please?
The scooter is still on the bench at present. How can I tell from the position of the arm if the gearbox is in neutral, before I fit the cables? Should it be symmetrically placed inside the selector box perhaps?
(Otherwise I will need to jack up the scooter, and see if the rear wheel is free to turn.)
