1B8710 Woodruff Key — Cat 320C 320D

This is a Woodruff key, a semicircular metal key used to connect a rotating shaft to a mating component, preventing relative rotation. Manufactured to precise dimensions, it ensures a secure and reliable connection, unlike a worn or sheared key that allows slippage. Operators may notice vibration, a loss of power transmission, or unusual noises from the connected components if this key fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A sheared or loose Woodruff key will initially cause slight vibration and intermittent slippage between connected components. If ignored, the slippage will worsen, leading to a complete loss of power transmission and potentially damaging the keyways on both the shaft and the component. Continued operation risks severe damage to the connected parts, requiring costly repairs.

Installation Tip

Ensure the keyway in both the shaft and the mating component is clean and free of debris before installation. Do not hammer the key into place; it should slide in with moderate pressure.

Service Note

Inspect the keyways on both the shaft and the mating component for any signs of wear or damage when replacing a Woodruff key.
