George Murphy wrote a great article on maintaining and repairing the servo. I can send a copy via e-mail if you are interested. Murphy also sells a rebuilt one that is upgraded to an aluminum housing.

 

Bratman,
I'm sorry I took so long to respond - I forgot all about this post! I appreciate your offer to send me the Murphy article, but I already have the MB Technical Companion, and I presume the Murphy article you're referring to is the one from that book. In any event, I appreciate your being willing to go that extra mile; people like you are what makes forums like this work.
Mike
