Ran d 24 #1 Posted April 22, 2019 Excuse me if I use some incorrect terminology here. I have a hydrogear assembly and am searching for any literature, service manual, etc for the gear motor. The Sundstrand manual that I have does not touch on this part of the hydrogear. Any info related to this what I call gear motor would be appreciated. Thanks!

gt14rider 797 #2 Posted April 22, 2019 Ran these pumps were replaced not repaired, Dman has a lot of posts on hydro gears, Aldon did a nice rebuild on hydro and gearbox, the hydro can be resurfaced if not to bad, instructional section of this forum has a few vidios Share this post Link to post Share on other sites
pfrederi 17,881 #3 Posted April 22, 2019 (edited) If the unit works i would not open the hydro gear part. It was repair by replacement. Edited April 22, 2019 by pfrederi Share this post Link to post Share on other sites
Ran d 24 #4 Posted April 22, 2019 I am just curious to see one of these disassembled and any paperwork associated with this assembly. If anyone has disassembled one of these, could you post pictures if you have them? Thanks! Share this post Link to post Share on other sites

Everything inside is machined to very close tolerances and there are no serviceable parts inside. Then hydraulic pressure is transferred from one gear to the other.

pfrederi 17,881 #13 Posted April 30, 2019 Open this thread. Not many people open up the hydro gear motor as there is really nothing much you can do to it. Why are you wanting to open yours.??... 1 Share this post Link to post Share on other sites
