Air in Hydraulic Fluid

[Snake]

Rick - Here is what I have from my best fixer -

Nice! Sounds like a challenge!!

Without fluid leaking somewhere, this will be difficult to figure out.

Every line, fitting, swivel, actuator and the pump manifold needs to be wiped very well with alcohol and swing the hell out of the gear.

This will most likely kill the pump, so keeping the pump motor cool will help last longer, but still will most likely ruin the longevity of it.

Hopefully a leak will be found after the cleanup. If there's just no leak to be found, I am putting my money on the pump/manifold. If that's not it, the only thing left is the rare case that there is a open in the system that doesn't leak, which will only be found by inspecting each mating surface of every connection.

The hydraulic fluid shouldn't foam up if the pump reservoir cap isn't sealed.

I will keep thinking about it, just in case a few of my brain stones collide and I have another thought. Let me know how it's going

Rick from snake I think he made an error in phrasing re: foaming, I think it will foam and did for me on an improper sealing of cap.

Keep you posted.

v/r snake Happy New Year.
