[QUOTE="Paulie, post: 1561312, member: 15969"] Killer tech support here:awesomework: Are you using actual hydraulic lines, 4000 psi ratings roughly. Im no expert but I've learned the pump should be lower than the rest of your system due to gravity and how fluids do bleed off (besides your cylinder). Orbital is one thing that traps air because it is mounted up high above the rest of the system. System bleeding is critical as you would already know. Hopefully the reservoir is big enough for the system meaning the pump isn't suckin it to a low enough level where your return fluid can't keep it full enough while at high rpm but is full while it's shut off. Hydraulics is a constant flow so if there is a resriction point, it would build up pressure more in a spot and restrict it to the rest of the way.
