Description

The Thermo King Large Shaft Crankshaft Key 559032 is a genuine, factory-certified OEM mechanical component engineered to maintain precise rotational alignment within transport refrigeration compressors. This heavy-duty 5/8-inch woodruff style key fits securely into the designated crankshaft slot, locking the drive gear, pulley, or flywheel firmly in position to guarantee zero rotational slippage under intense operational torque. Sold here as a convenient, high-value 3-Pack, these premium-grade alignment keys are precision-machined from hardened alloy steel to withstand continuous mechanical stress, high vibrations, and elevated temperatures inside the engine compartment. Proactively replacing worn or sheared shaft keys during compressor maintenance eliminates dangerous timing shifts, stops expensive flywheel damage, and keeps your transport refrigeration units operating smoothly on long-haul routes.
