I talked to Valerio otherwise no way to understand...
Recapping the WHOLE story according to Valerio:
The original failure that led to the "disaster" is defective right bearings.
The number of spheres inside is correct, the problem is that it has been mounted
with no grease at all!
When I opened both the bearings, the right one was without grease whilst the left one had still a fairly amount of grease.
Possible objection: no, the grease has been removed by high pressure water, you dumbass Impossible, because when the grease is present, the water simply slips away over the thin grease layer; moreover the bearing covers adequately protect the bearings from direct exposure to high pressure water (they were intact)
Why then it happened after 45.000 kms???I never rode the bike for long rides, only around my place: short and frequent tirps and at an average low speed.
This generated a minor overheating effect and the bearings lasted longer.
Yes, but you should have heard a progressive deterioration of the bearings, some kind of noise....No, because this would happen only for normal wear with grease. The lack of grease has instead generated overheating, not the usual play/noise, that ended up in the sudden "disaster"
No, it's a matter of how tight you tightened the axle: when you changed your tyre...14.000 kms ago??? and it lasted that long with no perceivable sign???
In my last clip I show you that tightening more or less is seamless because in the end there's a cotter pin locking everything thus a loosening cannot happen.
What did we learn from this??
Better to check when you change your tyres that the bearings are provided with grease! Hope I understood correctly and, most important, clearly reported to you!
