[GreenKeys] Main shaft fiber gear

[John, W9DDD]

A question for the folks that serviced 28s back in the day.

As I'm still sorting through the haul from a year ago, I find I have 7 
of 150439 60 tooth main shaft gears.  You don't find that in the 
documents unless you have an early issue (1149B original).

So the question is ... did these fail a lot and therefore was changed to 
Nylon early on?  Why else would a person doing service have this many 
when most of the other items in the batch were at quantity 2 (common 
screws, nute and washers being an exception)
