Attention troubleshooters and pump repair technicians:
What are the most common problems associated with 90 series Sundstrand pumps and motors?
What do you do to repair them?
What adjustments must be made?
What tests do you do?
What adjustments cannot be made in the field?
Thank you.

I would be more than happy to share my opinions on 90 series pumps, there one of my favorites to work on (what kind of weirdo has favorites?), but your question would be way more interesting to answer if we knew why your were asking. You post questions like your'e researching a book or something.

Sauer Danfoss has pretty detailed information on 90 series repair and setup.

Just got this freebie, too bad it was left outside with the case drain port up and open, it was in perfect running condition when it came off a debarker feed works.
