Product description

The Challenger A1072 Arm Restraint Outer Gear is the "Old Style" plunger component that directly engages with the inner moon gear to lock the lift arms. This straight-cut gear is part of the manual lock release assembly on early Challenger CL9 and CL10 lifts. When the operator releases the pull ring, this gear drops into the teeth of the inner gear, securing the arm's position. Over time, the teeth on this outer gear can wear down, preventing a secure lock and creating a potential safety hazard. Replacing a worn plunger with this high-strength steel part is necessary to maintain the reliability of the arm restraint system. It is designed for a precise fit within the old-style lock housing.
