Eaton Hydraulic Pump Woodruff Key - 1350

Eaton Hydraulic Pump Woodruff Key - 1350

This Woodruff key is a critical hardware component for securing the driveline yoke to the input shaft of Eaton 54 series hydraulic pumps commonly found on concrete mixers. The half-moon (semicircular) key sits in a recessed keyseat on the shaft, preventing the yoke from slipping or rotating independently under high torque. It serves as a fail-safe, designed to shear and protect more expensive pump and driveline components in the event of a catastrophic failure. This key is essential for replacing a sheared key or during the reinstallation of a hydraulic pump to ensure proper torque transmission.

Key Features

• Locks driveline yoke to pump shaft for reliable torque transfer
• Precision-machined from steel for strength and durability
• Designed to fit a standard 1.5-inch diameter keyed shaft
• Acts as a mechanical fail-safe to protect hydraulic components
• Conforms to ANSI B17.2 standards for Woodruff keys
