It provides the mechanical lifting force for one leg, using a 4-hole mounting pattern and a 17-inch travel range typical of the Magnum series. The unit is designed to be paired with a matching crank-side gearbox (AHEILR.T3.17.99) to form a complete landing gear system. Replacement is often required when internal gears become worn, stripped, or corroded, causing the leg to fail to extend or retract smoothly.
