Looking for diagnostic help

Got the engine dismantled without too much drama.
From the looks of the intermediate shaft gear, I am pretty sure it is the source of the shiny bits in the oil filter.

The gear tooth edges are burred, and the contact surfaces are pitted.
I wonder if there is a root cause for this.
The IM bearings are worn but not a crazy amount:

The crank bearings are in good shape except for the thrust bearing. The crank has 0.008" of end play, which is the wear limit.
The mating gear on the crank looks good.
Possibly the crank end float is beating up on the IM gear?

Its easy enough to replace the gear and bearings. Fortunately the existing gear is a code 0, which appears to be the only one available.

Any feedback about anything else that might cause this failure is appreciated
