case 730

rgeistel · Jun 8, 2016

my hydraulics dont work right. i took the hydraulic pump off and spent $750 to have it rebuilt. put it back on and still not working right. it will raise the boom about half way and just stop. when i try to pick up a small round bale of hay with it, it wont budge it. i replaced the hydraulic fluid when i reinstalled the pump. does anyone who might have run into this problem have any suggestions?

Did you check the pressure at the remotes that would have been a quick way to tell if the pump is the issue but it sounds like you have a internal leak that is causing fluid to bypass under load

I know how frustrating these situations can be, but the pressures and flow need to be tested in order for you to get information as to what needs to be repaired. It can
also be difficult to find someone who knows how to test it correctly. I can toss out ideas as to what to do, but it would only be a educated guess, perhaps wasting your
time and money. Just my two cents worth. Rod.

Tell us more about your 730, Earlier Eagle Hitch Style or later Comfort King. Where did you find a re-builder to re-build the pump?

As other have said, we need more info about your tractor and loader. If you have a loader with double acting cyls you may just have the hoses hooked incorrectly. I can't see your tractor setting here. HeHe.

Check the screen on the suction tube it could be restricting the flow of fluid to the pump
