[R-390] PTO Problems

[Jon Schlegel]

Thanks Craig,

I still think its reliably repairable but with some work.  The broken 
roller shaft is the only real bugaboo.  The other effort is getting 
it cleaned well.  There was a lot of corrosion and crystalline silica 
gel all over inside.  If I can get the roller repaired I should be 
home free (famous last words).

Regards,
Jon
