TTR bearing spacer: is it needed?
Posted: Mon May 22, 2023 6:13 pm
This concerns the rear outer stub axle. I have fitted a narrow bearing to an issue 18 stub axle, ie,
takes the wider bearing, hence the circlip groove is further from the 'fingers' of the axle. This will be installed
in an issue 16 upright. I thought I needed this:

Assuming all TTR hubshafts take the wider bearing, I'm not sure this is needed at all in an issue 16 upright.
The bearing on the stub axle is up against the casting in the inside and is held in place by the big
circlip on the outside, so it seems it doesn't matter whether a circlip is used or not. Am I missing
something here?
As I think about this, I'm not sure if a circlip is needed at all, on the inside, regardless of the upright type
or axle, UNLESS, one is fitting a narrow inner bearing to an issue 18 upright, because then the extra
space is needed to be taken up by the spacer. Hmmm,,, is it possible the TTR description is incorrect?
