Hi Buly, Sorry for the delay on your input shaft.  It has been pinned & ready to go but closer examination of the thrust bearing showed it was more damaged by the misalignment than I first noticed.  Ordered a replacement but it was back ordered 6 weeks.  I have changed to the RD-1C type (two stage needle bearing) for all drives now and that is the one I'll send with your shaft.

 

I'm posting this here to avoid mass confusion over the change.  There is nothing wrong with the original roller thrust bearing used on A & B drives and none have ever failed.  The change for the C drive was made for the higher RPM range used with the higher ratio drive.
