Rotax 122 - Aprilia RS 125
Removing of the last blind bearing with bread

[@CHEEESBurgerMAN]

... This tutorial saved me buying an bearringpuller... my primarygearbearing was still inside the housing and didnt came out ... a toast and done :D Thx for this tipp... but attention... researching this method in the internet showed me that if the material behind the bearing is to thin ur casing/enginehousing can break (get a hole)

Old school ;)

[@JaapGrootveld]

Nice!

[@miguelmarquez7129]

what bread?

[@Crisstian1973]

This work must be avoided if you want to lose the interference between the crankcase and the bearing. The correct way is to heat the crankcase to expand the aluminum and thus extract the bearing.

In what did u soak this bread?

[@romainquiban5469]

I didn’t soak it, it’s bread that I have previously used for others blind bearings removal. So it seems wet because of the residual oil in the bearings !

[@Tiwey]

only gluten free bread?

[@romainquiban5469]

It may work with gluten-free bread, but it is better with normal bread, because gluten make cohesion in bread

@@romainquiban5469 do you have any experience with replacing your bearings with Polyamide cage bearings? It's a little more expensive but should make running noise Lowe

[@romainquiban5469]

@@Tiwey I never tried, I’m curious to know if it really reduces noises

[@Tiwey]

@@romainquiban5469 I will try them out. If there is a noticeable difference, I will come back to you. There are sadly no reports or reviews of these bearings. They seem great. I learned that changing the piston needle bearing to Polyamide already reduces vibrations
