[R-390] PTO Problems

[Craig C. Heaton]

Jon,

If things are rusted that much, I'd look for another PTO. Other parts may
have failed inside or are about to. Booted my other PC to check some notes,
didn't find any information as to the roller/wiper on the two arms. 

In all I had quite a bit of labor invested in fixing my PTO, I'd hate to put
too much time into one rusted like yours, only to have it fail in a short
time. Someone on the list will have a repairable PTO to offer.

Craig,

Hi all,

This PTO may be in pretty poor shape.  After 
cleaning, the fiber roller's staked in shaft 
broke off with only a reasonably gentle wiggle to 
see if there was any play to allow things to get 
going again.  I should be able to fix it if I can 
find suitable non-magnetic odds and ends to use to make a new shaft.

There is what appears to be a stainless "roller" 
that follows the opposite side of the corrector 
stack.  Is this "roller" supposed to spin or not as it follows the stack?

Also, a few weeks ago I recall some list members 
working out some backlash problems.  I can now 
see that I can see numerous spots where backlash 
could creep in that might need adjustment.

Regards,
Jon
