pfrederi 17,879 #2 Posted July 2, 2019 Have you changed oil an filter?? Classically sounds like a worn out pump/motor. This manual has good diagnostics. 1 Share this post Link to post Share on other sites

Could be a worn out pump, but I would service it before I drew any conclusions. 10W30 and a Wix 51410 (or napa 1410) filter if it has engine oil in it. If it has ATF in it, refill it with that. 3 Share this post Link to post Share on other sites
daveoman1966 3,762 #4 Posted July 2, 2019 (edited) Don't let the word 'rebuild' scare you off. These Sundstrand units ...pump and motor...can be brought back with new life in a few hours and for less than a C note IN PARTS. I have overhauled dozens of these...4 or 5 hour job. First though, as ZXT says above, change the oil and filter. Download the repair manuals too. Edited July 4, 2019 by daveoman1966 4 Share this post Link to post Share on other sites

PARTS should be under a C note and most are available on-line. I would do this for you, but will have to pass. I can, of course, give a ton of moral and directional support....as well as for some parts if needed. If you can turn a wrench, twist a screwdriver, manage sandpaper, YOU can do this. MAIN caution to you: keep everything spotless clean in your work area AND during rebuild process. I have a write up on the process....will dig it out from somewhere (?) and get it to you. Did I get to you an O-ring and seals list??? Share this post Link to post Share on other sites
