What must be done when changing a landing gear assembly?

When changing a landing gear assembly, it's crucial to match the operating heights to ensure proper functionality and compatibility with the trailer being supported. The height at which the landing gear operates affects how the trailer sits when coupled to the towing vehicle and can influence the stability during loading and unloading.

Matching the operating heights ensures that the landing gear provides adequate clearance and support when the trailer is loaded, preventing potential issues such as tipping or uneven loading. This process involves verifying that the new landing gear can extend to the appropriate height required for the specific trailer configuration and intended load.

In addition to this, while timing gears, performing alignment, and matching lifting capacity might be important in other contexts, they are less critical specifically during the assembly change process. The primary focus in this case centers around the operational aspect and ensuring that the new assembly behaves correctly under the expected conditions. Adjusting the operating heights appropriately prevents complications and promotes safe handling of the trailer.
