[Collins] Re: {Collins} 70K-2 PTO

[Rodger]

Henry,

I just went through the cleaning and lube process on the PTO's  in my 
32S-3, 75S-3, and KWM-2 and it really does make a difference in feel.  
You might email Fair Radio ( fairradio at fairradio.com ) to see if they 
have any "destroyed units" that they would steal the ball out of for 
you.  I think that the glass ball used as the thrust bearing in the 
command sets is probably larger but I will take a look at one of my 
parts units later to see if it looks close and if so I will compare it 
to the one in my 51S-1 when I go through that PTO later.

I wouldn't give up hope on finding it yet since it probably had some 
grease mixed with "ferrite dust" which makes it somewhat sticky so it 
wouldn't likely roll too far.

Good luck!
