Lippert 6 Point - Front Landing Gear - Sequence?

[raineman]

I thought I remember reading a post that mentioned that the front landing gear on the Lippert 6 point leveling system should go down at the same time instead of one at a time. Mine used to go down together. Now the passenger side goes down first. The driver side does not go down until the passenger side touches the ground.

Questions:
1.) Are the front legs supposed to go down simultaneously?
2.) If yes, how do I set them back to going down at the same time?

Thank you

I believe it is a hydraulic system, and the second leg does
not go down until pressure builds up after the first leg
contacts the ground and starts to put a "load" on the
hydraulic system. My LCI system works exactly as you
have described. After you level the front to back, then when
a side needs to be leveled, one of the front or rear legs
will loose pressure as its partner is extended and then
comes up to pressure. They will not deploy together until
they both acquire a load from contact with the ground.

I'll jump in just so that you aren't left hanging; I know nothing about that particular system, but probably there is nothing that co-ordinates the travel of those hydraulic pistons. They are powered by the pump when the valve opens, and they push at low pressure until one or the other encounters resistance. At that point the pressure builds up to push against that resistance. If one piston is lagging because of a little friction, the higher pressure will quickly cause the laggard to catch up. From then on, they should push about evenly, but they are still not actually synchronized.


My opinion is that it's no problem and no solution, either. You could try cleaning and lubricating the exposed piston rods, and that may help.

OK, Mac beat me to it.

Thank you. Makes sense.

I have the same system. The pressure to both front jacks is independent but applied at the same time. It just depends on which is most restricted as to which will move first. They are supplied by a bank of solenoid valves on a manifold.

You should lube the shaft every couple times to keep the seals lubed. And keep the shafts clean of all dust and debris.

Ihabe a 6point and the rt fro t leg always goes down first. Probably because it is closest to the pump. Works fine

[jacknife]

The seals are lubed internally by the auto trans fluid .

My LCI struts also act the same - curb side down first then street side. My front struts used to make a popping sound, while parked, until I started spraying silicone on them periodically. Now all is quiet.

This is interesting. Mine do the same.

I have a curt hitch. From the day I purchased it I have had problems unhitching. Called them more than once and finally concluded that the hitch is binding due to the way the landing gear lowers.

So I explain that all the new 6 point systems do this. The tech would not believe me and refused to honor my warrantee and provide a fix.

Just an FYI

[jacknife]

I don't understand why you can't move the legs independently to get your hitch out without binding..

[edrayman]

You can not. As others have said. One moves down then the other. When retracting it is the same way. The legs do not move together.

Curt refused to believe me. They did say that if it was true they would have to completely redesign the hitch head.

So my next step is to send them a video and setup a conference call between Curt, lippert, and me. Then maybe they will believe me and fix my hitch.

[jacknife]

I understand that but you can move rt side left side manually after the legs are down, not to say that will unbind your hitch but the legs can be manuvered that way.

Unhook the hitch while all on the ground?
