1B8706 Woodruff Key — Cat 320C 320D

This Woodruff key is a semicircular metal key used to connect a shaft to a component, preventing relative rotation and ensuring positive drive. Manufactured to meet precise OEM specifications, it provides a secure and reliable connection, unlike a worn or broken key that can lead to slippage and loss of power transmission. Observable symptoms of a failing Woodruff key include intermittent loss of power, unusual noises from the connected components, or complete disengagement of the drive.

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 failing Woodruff key may initially cause intermittent power loss or a slight hesitation in power transmission. If the key continues to wear or break, it can lead to complete loss of drive between the connected components. This can result in the inability to operate the machine's functions or move the equipment.

Installation Tip

Ensure the keyways on both the shaft and the mating component are clean and free of debris before attempting to install the key. Never attempt to drive the key into place with excessive force, as this can damage the key or the keyways.

Service Note

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