Mannheim 510 JD

[Pult Eater]

I have a 1966 Mannheim JD 510 that I have rebuilt the engine. I stripped the front end right down of
course which involved removing the hydraulic pump. I have followed the instructions in the service
manual to bleed the system but can get no response to any hydraulic movement. No power steering, no
3 Pt hitch, no remote. Can someone suggest what my problem may be? Thanks

Did you check the hyd screen? It on top of rockshaft housing, held in by three 10 mil studs.It can be cleaned.I never seen one with power steering.If it has it would have a flow divider mounted on rockshaft.Sometimes the o rings fail in them, if they are bad the are metric o rings.A place to start looking.
