Weak dump hoist help!

[Jehinten]

The old unit may have grounded through the frame, I couldn't tell from the pics. I'm glad you got it fixed without the headache and cost of moving the cylinder.

Glad to see you got it working again, and that a new pump fixed it! I think the hoist is in a good place to lift the bed, sliding it back would give you a steeper dump angle, but also require more power to lift the bed.

Odd they used a frame ground for the old pump, that was probably part of its problem- something that draws as much current as that pump definitely needs a dedicated ground.

As for the reason a power up/gravity down hoist would have two lines, maybe that pump allowed the upper hose to vent through the valve body somehow. Usually there’s just a little vent plug in the top end of the cylinder, but maybe that one was vented differently for some reason.

That's gotta feel nice to have it fixed.

Have you or are you going to pull the old pump off the old reservoir? If I'm not mistaken that's where my screen was. I'd be interested to also hook the old one up straight to a battery and put a pressure gauge on it to see what its output is. Might be salvageable.

No. I haven't yet, but I plan to.
