Hobart 012430-00040 Square End Key 3/16 X 3/16 X 3/4 in

Product Description

The HOBART 012430-00040 is a genuine OEM square end drive key designed to maintain secure, precise connections between rotating components in commercial foodservice equipment. This small but critical hardware piece locks drive shafts, pulleys, and gears into alignment, preventing slippage and ensuring consistent torque transfer during operation. At 3/16 inches wide by 3/16 inches tall by 3/4 inches long, it meets the exact dimensional tolerances required for a proper fit. Licensed HVAC and commercial appliance technicians, as well as qualified foodservice equipment service professionals, rely on OEM keys like this one to restore equipment to factory operating condition.

This key is suited for commercial dishwashing systems where drive train integrity is essential to cycle performance. Compatible models listed by the manufacturer include the C44AW, C44A, and C54A commercial dishwashers. It is a direct OEM replacement intended for use in rack-type and conveyor dishwasher configurations found in restaurant, institutional, and hospitality environments. When a worn or damaged key causes shaft slippage or erratic motor-to-pump coupling, this part restores the mechanical connection to specification.

Installation Notes

Installation of drive keys should be performed by a qualified commercial appliance or foodservice equipment technician. Disconnect and lock out all electrical power to the unit before accessing any drive train components. Inspect the keyway slot and mating shaft for wear or deformation before installing the new key, as a damaged keyway will prevent proper seating and may cause premature failure. Do not force the key into an undersized or misaligned keyway.
