One New Aftermarket Replacement Woodruff Key for Caterpillar (Cat) Equipment
This aftermarket replacement Woodruff key (No. 10) is used in the oil pump assembly on Caterpillar (Cat) construction and heavy equipment. The Woodruff key seats in a milled slot on the shaft and locks the driven gear or sprocket in position, transferring torque and preventing rotational slippage between the shaft and the mating component. Replacing a worn, sheared, or damaged Woodruff key restores proper oil pump drive engagement and helps maintain consistent oil pressure throughout the engine.
Specifications
- Type: Woodruff Key, No. 10
- Application: Oil pump shaft
