Am I wrong in thinking no matter, how hard you nip up that nut, whenever there is too much play within the splines of the carrier-gearshaft fit, you will never get the nut fixed for good : One side of the assembly stays put, but the other half will move with torque coming from the effectively non-existant ESA or from the gear shaft. Anyway, the torque going into this assembly must be exceeding the max chain load of 2 or 3 tons that break even that triplex chain ??? So I question being able to torque down the nut to fight these loads . You will only get wear in highly loaded shims that get eaten by micro motions due to play in the splines. So maybe one should be looking into fabricating hardened spacers that keep the carrier in its place without squeezing it with the nut. You can get hardened shims from axial needle bearings for adapting some sort of shim that will survive for a lot longer than thin soft shims. Or am I all wrong in my thinking? This trouble is very similar to the woes with the sprocket nut for the rear chain as recently discussed here.
