1B8707 Woodruff Key — Cat 320C 320D

This is a CAT Woodruff Key, a small, semi-circular metal key used to transmit torque between a shaft and a mating component, preventing relative rotation. It is manufactured from high-strength steel to withstand significant torsional loads and ensure secure component engagement. A worn or missing Woodruff key can lead to slippage between connected parts, causing loss of power transmission and potential damage to the shaft or hub.

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

The first sign of a failing Woodruff key might be a slight hesitation or slippage during load changes. If the key shears or becomes loose, it will result in a complete loss of power transmission to the connected component. This can lead to the inability to operate the equipment and potential damage to the shaft or mating part.

Installation Tip

Ensure the keyway in both the shaft and the mating component are clean and free of debris before attempting installation. Never attempt to drive the key in with excessive force; it should fit snugly but without binding.

Service Note

Inspect the keyway on both the shaft and the hub for any signs of wear, cracks, or deformation when replacing a Woodruff key.
