[R-390] PTO Problems

[Craig C. Heaton]

Jon,

I had the same issue with a PTO in a Motorola R-390A. After applying liberal
amounts of elbow grease, life was good. The desiccant was scattered
throughout the PTO, stuck to the shaft that moves the widget along the
corrector stack, ugly but fixable. 

First, I wouldn't do anything to move any of the plates of the corrector
stack! Clean the inside of the PTO as best as possible. Check the condition
of the little spring used to keep pressure between the widget and roller
which moves along the corrector stack. A little De-Oxit here didn't hurt my
PTO. A drop or two of synthetic 90 weight on the threads of the shaft didn't
seem to hurt either. Reassemble the beast and adjust the end-point per Y2K
manual. Keep your fingers crossed, the linear points are close and the
plates of the corrector stack are where they should be. If the plates need
adjustment, it will be a long night.

Hi all,

The PTO shaft seemed way too stiff so I opened it up and found this 
amazing colony of crystalline entities growing all over inside.  It's 
a real mess.  It looks like it had a LOT of moisture in it at one 
time but the rest of the receiver doesn't really show signs of water 
problems.  Nevertheless the PTO looks original to the receiver (both
Motorola).

Should some kind of repair attempt be made or should go out with next 
Thursday's trash?  I have an interesting photo but I suppose that 
would be inappropriate for the list.

Regards,
Jon
