R12 gearbox rebuild

Hello,

In the process of rebuilding my R12 gearbox and I have a couple of questions:

Any key issues to look out for i.e. kick starter set up
Is the notch in the rear input shaft bearing carrier there for a purpose? I bought a new one but it doesn't have the 'segment' out of the rim to accommodate the piece of metal that is screwed into the case?

Regards

John

I redid my R12 gearbox ages ago, and I (vaguely) recall that the notch is there to provide clearance for the kickstarter ratchet pawl. I wish I could give you more specifics.

Thanks Darryl,

You're correct. I located the kickstart in position and without the section removed the kick starter ratchet pawl won't seat. I've sent photos to the manufacturer. See the alternative from Hugget.

Anyone have a picture of one with the section removed? If I have to modify the one I have I'd like a pattern to follow?

Regards

The process to fit this is to remove the section from the bearing carrier for the kickstart once the carrier has been pressed into place.
