I have a Steiner 220 putting out 1200 psi on an output port on the hydraulic control valve bank.What should the pump psi be and is it likely that the valve bank has a lower pressure relief valve and can I raise the pressure if so?

 

Is a permanent magnet alternator directional?

Alternator doesn't care which way it spins.

Hard to say on the Steiner. 1200lbs would be low for a compact tractor which are typically in the 2000-2500 range, but a bit higher than most GT's which are usually in the 600 to 1k psi range. A brushless PM alternator won't care what way it's turned but a brushed alternator that has been used in one direction will be noisy and hard on the brushes if turned the other way.

Well I have a forklift attached to it and I am only getting less than 500 lbs of lift instead of the 1300 that it is rated at.It was run with and electric over hydraulic pump with obviously a lot more pressure.I would have like to run it with on board hydraulics but I don't think that is going to happen.
