Firstly unless you want to modify the machines there are no options
For me 2k on a clutch thats worn calls for a replacement.
That being said however i have seen tons of clutches work untill they simply died.
Firstly, grooves or bumps on the sheaves is a replacement without a doubt in my opinion.
Again ive seen them where the customer chugged on but its not healthy for the belt either.
Secondly if you know how clutches work these are actually rebuildable to some extent.
This is a hpx driver clutch and you can replace the "clutch spider" when the rollers get worn and is a job we do often aswell
Now we dont do alot of the tx clutches and we normally replace them outright but theres a spider kit for these aswell.
Hell if i know if they are even available because like i said ive never done a spider on a tx.
Lastly the rear varios only wear on the tracks and the little rubbers wear out.
Here we simply call them little [email protected]
on the rear vario so excuse my lack of terminology lol.
Again the runner thingies can be replaced but only if the metal is not worn or weird looking.
Once theyll look bad youll notice soon enough.
The rear once will normally not break in any place other than wear out an those spots or develop play
So to be honest: replace the front hpx vario, repair the rear if possible and inspect the tx varios for damage play etc.
If they get sticky or have alot of movement on the shaft its time to move on.
Adendum: clean them, check rollers on spider and also check the aluminium that the spider slides in as this will also wear.
And again: once the alumium on the rear of the sheave or the sheaves are worn its game over.
