    I have a 10' Uni Mount MC

    I drained the complete system, pump housing, removed the hydro lines, and cleared the large rams.

    We started to refill the hydraulic fluid, back and forth up and down about 100 times.

    Its very slow left to right but that's normal

    How does the air bleed out from the lines and such? There is no breather line like the newer Fisher pumps?

    I'm sure air is in the lines as when I take off the filler cap, frothy hydraulic fluid comes rushing out

    Cycling it left and right a few times should take most of the air out. Letting it set so the air settles out of the fluid and refilling it should do it.
