How To Lubricate A LUEN Trailer Landing Gear

This article will explain in detail how to lubricate LUEN trailer landing gear and how to solve the landing gear corrosion problem.

There are two main parts of the LUEN trailer landing gear that need to be lubricated on a regular basis: 

the grease reservoir and the lifting screw.

As the gears turn, the lift nut distributes grease to the lift screw with each operation The heavy duty trailer landing gear should be lubricated every 3 months, or more frequently in excessively wet conditions To be safe, use a lithium-based 1% to 2% lubricant Always lubricate the trailer when it's attached to the tractor truck The grease fitting for the gear train is located at the front end of the ER's upper tube Lubricate the top fitting with 4 ounces of grease if You will need about 50 ounces if you are using a hand grease gun. Confirm the amount of grease dispensed to the unit with the pump, apply grease to the cardboard placed on the scale until 4 ounces are applied, making sure to record this data so that the process can be repeated.

Lubricate the grease reservoir to lubricate the screw while operating the landing gear, and after completing the lubrication procedure, fully  extend and retract the lower legs to lubricate the entire lifting screw.If your heavy duty trailer landing gear crank turns hard or is frozen, the only cure is periodic lubrication, follow these steps: first disconnect the crossover shaft and rotate each leg by hand to see if one or both legs are affected; then, if the crank turns hard, remove the leg cover, push the grease away from the gear train, and as close to the screw as possible pour 2 to 3 ounces of 90 to 180 wt. gear lubricant.

If the mechanism is stuck, loosen any rust and scrub it as normal, or if the mechanism is stuck, remove the bottom grease fitting, spray penetrating oil directly on the screw for 30 seconds and leave it overnight, then crank in low gear to loosen the part.

If your trailer landing gear is left unmaintained for a long period of time, or lacks regular maintenance, it can cause the product to corrode and rust, reducing the life of the landing leg, so remember to maintain the even on a regular basis.
