Ever Eternal lift install, weird behavior

[pumalex]

Hey everyone, i am almost done installing my ever eternal lift and i am having a hard time understanding what's going on.

When i first lift it, the main cylinder will raise quicker than the second cylinder, which would throw the balance of the car off a lot. The second cylinder will eventually catch up the first one and end up being level but not sure i want to install a car on it as long as this isn't figured out. Also, when i lower the lift, the second cylinder is lowering in a jerky matter. The only thing i can think off is if air was trapped in the hydraulic system. There is absolutly no mention of that in the small manual they gave with it.

Anyone with a Ever Eternal lift had that problem when they first fired it? Is that a normal behavior

For the hydraulic experts, i included a copy of their hydraulic diagram so if anyone has a clue as to what's happening or can help me, that would be appreciated. The way it is designed is that the first cylinder while raising it's part of the lift also send the oil to the secondary cylinder.

Here is the first video where we can see the lift uneven untill thye finally gets within level.

second video is of the jerky lowering

last is the diagram

no 3 in the diagram is the valve to put the two cylinders level so it is normally closed.

Just wondering if it needs a load on it? That would possibly cure the slight jerkiness on lowering and may help the synchronising of the ramps when rising?

Put a car on it, if things look like they're going **** up just stop it and lower.

****** noisey too!

no it isn't really noisy, i was just next to the pump and i removed the door of the small cabinet.

Assuming the cylinders are connected per the diagram, put a car on them and go slowly. It may be one lift is tighter than the other. On a different note, I thought mine was lowering to quickly so I adjusted the flow control on the return circuit. Since doing that I haven't had to use the manual valve to get the cylinder re-timed. Any air should work itself out after operating with no load through full travel a couple cycles.

hmm well i guess i'll try a car then, thanks

I would call the factory or look up how to bleed it before putting a car on it. At least don't take the car up that high.

I would bet with a load on it, both of your problems go away. Even my bend pak has a slight shudder with no load coming down.

guys you were right, i put a car on it and had to readjust height and it now works like a charm. I will take some pics once everything is finally done and post it on the forum.
