Hydraulic landing gear drifting

This is a common complaint with the Level-Up system and Lippert has a solution. The answer is to add some anti-stiction oil (aka fork oil or ?) to the reservoir. The complete description is here: Lip Sheet-0295

Here is part of the writeup describing the recommended oils:

If there is a popping noise in a Lippert Leveling system, Lippert has approved adding a quart of anti-stiction fluid. Approved fluids are listed by brand name and fluid characteristics below:
1. Torco RFF Grade 15 (Fig. 1)
2. Maxima Fork Oil Grade 15 (Fig. 2)
3. Caterpillar Hydraulic Oil Additive 1U-9891 (Fig. 3)

I used 1 quart of the CAT fluid (not-cheap) and it solved the problem for me.

Not only the valves, but the cylinders can leak internally past the piston and o-rings.

Valves usually leak internally. Sometimes you can take then apart and install new "O" rings sometimes the valve body has a scratch and nothing short or replacing it will help.

It is FORK oil like used in motorcycles. It took 2 quarts to get mine to settle down.
Go to Lipitor web site for detail instructions.

You might check the Lippert web site, but this is a known problem that occurs once in a while. I believe the fix is to add some CAT transmission fluid to the reservoir. The fix is pretty specific on what type of fluid to add but I am going from memory and we all know where that gets you sometimes.

Something you can try:
Put some solid blocks under the feet to reduce the amount of extension.
Completely lower and extend the landing to remove possible air.
Be sure your wheels are chocked well.

Thank you donn. I checked for oil and found none. Maybe leaking back into the tank I guess.
