hydraulic rebuild time

[freebird]

My hydraulics still don't work. I have decided that it must be up in the resivoiur tank. I may have a clogged screen or somethng. I can see the fluid level drop slightly as I activate my lever back and forth, but that's it. I even tried to pressurize the tank with a fitting and compressed air...no luck. i will be making a list of parts from my catalog on what to order.
Is there a kit of parts anyone knows of that includes all I need for this job?

Freebird, What type of fluid does that unit take??

Hy-Tran. I've used AW10 I think it's called......standard tractor/farm hydraulic fluid. I know the pump is working, just can't make the rockshaft move.
