Hello everyone,
Looking for those who are more experience with this sort of thing than I am.
My 1963 Case 530 Loader/Backhoe just pushed the seal out of the hydraulic pump: typically a strong indication of a worn out pump as I understand it. Can anybody verify that?
Now of course this pump was used on seemingly any model with the 188D.
Can come off any of these models: 310G, 400, 450, 450B, 450C, 455B, 455C, 530, 550, 580, 584, 584C, 584D, 585D, 586, 586C, 586D. Pump was also used on Fords, New Holland, and Deere.
Case Part Numbers: D31254, D41390
As I understand it, this pump was originally manufactured by Cessna, then Parker/Eaton, then Danfoss and Im sure I am missing somebody in there..
Cessna #'s: 25503RSA, 24527-1AAC or 24504-LAN
SPECIFICATIONSDisp. 2.98 Inł/Rev.
PSI 2,500 Max.
RPM 2,500 Max.
23.2 GPM @ 1,800 RPM
30.6 GPM @ 2,500 RPM Max. Rotation CCW
Mount 2 bolt SAE B mount
Shaft 7/8" dia 13 tooth splined
IN Port SAE 20
OUT Port SAE 16
So nobody makes these pumps anymore I guess because remanufacturer is all I can find available to the tune of about $600.
But I found a specification equivalent from Maine Hydraulics:
P51 Series Bi-Rotational Gear Pump
23 GPM - 33 GPM @ 1200 RPM available.
7/8” 13 tooth spline shaft, 2500 PSI max pressure, 2 x 4 B flange.
$434.70 - $450
Additionally, I found two other products that seem to meet the required specifications:
The problem is, I do not have a lot of experience with this sort of thing and am wondering if anyone could confirm or deny the 3 equivalents I found. Of course I am in the middle of a project so time is a factor for me. Im currently using a soft bucket to catch the leaking fluid and carrying on due to necessity.
Any guidance appreciated.
