You can also take the numbers/code stamped on the old bearing and do a search at 123roulement dot fr or similar

So ordered the new bearing but has anyone got any tip for removing the old bottom one.


I was thinking a heat gun after putting the lower tripple clamp in the freezer. Or is there an easier way to do this.

Thanks Larry

Aim the chisel between the bearing and the lower yoke. If you take more care than I did you'll get away minimal marking on the lower yoke. Work round the bearing easing it up

+1 on the chase it off with a chisel- just make sure where you clamp the stem in the vice that you clamp a non-critical area (not where the bearings sit) - if you have access to to a propane torch or similar heating the old race will help

Unlike what "another brand/model" Moizeau is showing where race is full pressed flush with lower triple tree, your Z/KZ is only flush on the most inner section around the shaft. Meaning there's a relief purpose built into this race to facilitate use of a double lipped rubber seal. While you can pound away with a chisel using it as a wedge i just simply use a bearing puller/separator. walks right off with no      damage or pounding.

Just looked at his photo again, yeah, a bearing puller would work as there are no lock stops in the way. My photo is a GPz11 Uni

I would completely agree if you have a suitable puller- if not I have never had a significant issue chasing these (and half shaft bearings) off with a chisel

I will try it today in work I only have a small vice at home so i could not do it but I have the tools in work.

I was thinking about a dremel also.

So I might aswell ask how about putting the new one on any advice?
