hough 65 b (diesel) steering

Need help or ideas.Have tried all I know
to get this old dogs steering to work.
Vickers 2521---9 vane pump new carriages
Front and back. Front pump works great.
Rear pump 350 psi Max. Checked hoses spitter
valve actuator valve cylinders all looks OK. This rear pump I have had apart 5 times. I have installed it by the book and not
By any book still 350psi only? Guess now don't
Even know the right way to build it.
Sure am good at draining and filling hydraulic
Fluid lol.Anyone have this problem before?

Thanks hazfun7

Thanks for the reply. I think you hit the nail on
The head. I had no idea what the triangles were
for?.Also my manual says "pump is part of a Vickers 2521. OK the new parts (carriage) has
brass wear rings my old one did not.The old one
had a rear spring new one does not appear to need
the spring.?Do I install the new kit as is
Or parts of old and new? Again Thank you Hazfun7
