Hi,
This has happened twice to #1218 it was the drive gear in the auxiliary case, this gear drives both the fuel pump and the power steering pump, it wears off the internal splines of the gear and the pump, the Cat gear is softer than the Eaton pump! a new pump may work for a while but it will wear the pump splines off very quickly. a replacement gear was available at Caterpillar Belgium and was quite easy to fit, you can also replace the shaft it's an Eaton Vicars pump and spare shafts are available in Italy!!
The biggest worry is that all the metal fragments have gone into your engine oil!! I took my sump off and cleaned it, quite a lot of fine metal in the sump.
