[GreenKeys] AN/UGC-74 service manual or pinouts

[Kirill Levchenko]

Thanks for all the replies. It looks like it is indeed bad rollers. I  
wanted to make sure I understand which rollers disintegrated. It looks  
like there are two black rubber rollers which seem ok, which pressed  
against what is now just bare metal. Here's a picture:

Can someone with knowledge of the UGC-74 confirm that the two rollers  
that are now bare metal are the ones that had the disintegrated  
polyurethane? Also, what thickness?

Thanks,
Kirill
