Key Features
- Genuine OEM Quality — Manufactured to Genie's original dimensional and material standards, delivering the same precise fit as the part it replaces.
- Direct OEM Replacement — Drops into the crankshaft position without modification, restoring the drive connection to its original condition.
- TMZ-50/30 Fitment — Confirmed for the Genie TMZ-50/30 trailer-mounted articulating boom lift.
- Maintains Drive Integrity — A correctly fitted crankshaft key locks the rotating assembly in its proper timed position; a worn or sheared key causes slippage and loss of engine or drive function.
A crankshaft key is a small but critical component that seats in a machined slot between the crankshaft and a mating component — such as a pulley, sprocket, or flywheel — to prevent relative rotation between the two parts. It ensures the mating component is locked in the correct angular position and transmits torque without slipping. If the key shears or wears, the driven component can shift out of alignment, causing immediate loss of function and potential damage to surrounding components. Replacing a damaged key promptly with the correct OEM part restores proper engagement and protects the integrity of the assembly.
