NAA three point failure

vmaxk · Jun 25, 2021

Does any one know how to determine causes for failure of three point hydraulics on a Ford Golden Jubilee? I suspect the pump because of foam in the fluid but how do I tell whether it is something else?

A good start is to check the pressure at the port on the plate under the seat

No flow would make me suspect pump. Foam
would tell me gasket or some other leak
letting it squirt where it shouldn't.

Yes you need a gauge,foam means a leak,bad pressure relief valve,cracked line,maybe a bad lift arm cylinder. But it is all just throwing parts, till you get a gauge and follow the diagnostic charts.
