Why Trailer Landing Gear Hard To Turn

The primary factors contributing to the stiffening or malfunction of LUEN landing gear are infrequent operation and potential bending. Notably, the Holland landing gear variant, which frequently encounters such issues, incorporates two strategic grease points: one positioned atop the gear case and another slightly lower, aimed at lubricating the threads and leg mechanism. Enhancing functionality, one can detach the lower grease fitting and employ an oil pump to infuse oil directly into the gear, as oil permeates more efficiently and effectively than grease. Injecting oil from the top would result in a prolonged process for it to seep through to the lower regions, emphasizing the importance of administering oil within the leg section. Furthermore, inadequate greasing can lead to the jamming of bevel gears situated at the landing gear's summit.

Occasionally, trailer legs, due to disuse, accumulate rust at their telescoping joints. To mitigate this, gently tapping the reinforced base of the leg with a hammer facilitates the dislodging of rust particles. Continuously repeating this while maneuvering the trailer leg's extension and retraction, followed by a thorough greasing from top to bottom prior to retraction, aids in preserving its functionality.

Moreover, the internal components of two-speed gearboxes are susceptible to rusting and subsequent malfunction due to insufficient greasing, which invites moisture intrusion. In cases of severe deterioration, it is economically prudent to replace the entire landing gear rather than attempt repairs.

The LUEN Group advocates for regular movement of the legs in daily routines, as a proactive measure to prevent stiffening and extend their operational lifespan.
