336 Transaxle impossible to remove bearing?

[314159td]

Currently gutting a 336-20 transaxle from a S1, and it looks like every roller bearing is in the early stages of failure - one example attached, but they all look exactly the same so far. Reading the manual, they're trivial to inspect and replace, except the strange one at the pinion output end of the secondary shaft.
It seems like it doesn't have a cage, and there is this ominous note in the workshop manual:

"As the roller bearing inner track-ring is bonded to the shaft, this
bearing cannot be removed."

Not 100% sure what means. Renault 16 shop sells that bearing, and the secondary shaft without the bearing installed (paired with the differential gear). If that bearing is worn do I just have to get a new differential gear set just to replace it or...?

I replaced that bearing.  It's not easy but it is possible.  FIRST, make sure you have the correct replacement to hand.  I bought mine based on dimensions.

To remove the old inner race you are going to have to VERY CAREFULLY cut it off.  You do not have to cut it all the way, just 95% of the way.  I think I cut it in two opposite places -- been a while.  You then install the new inner race with the strongest locking compound: green, permanent, bearing mount.
