Expert Maintenance Review
The 1" hex bush is the critical sacrificial wear point within the cross auger assembly. Constant torque and vibration eventually lead to the rounding of the hex internal profile, which can cause intermittent drive failure. We recommend inspecting the hex bush for "backlash" or rounding during every preventative maintenance check to ensure consistent crop feeding.
Upgrading to this high-performance bolt-in kit is a smart choice for large-scale operations. Once the initial C&M internal hub is installed, replacing this extended wear bush becomes a simple field task, ensuring your header remains in top condition without the need for specialized tools or welding. This modular approach provides a significantly longer service life for the overall auger assembly.
Installation Tip: Fastener Security
When installing your new 1" replacement hex bush, always use new high-tensile fasteners and apply a medium-strength thread locker. Because this bush transmits high levels of torque, ensuring the four mounting bolts remain tight is essential for preventing vibration. A secure, high-strength fitment ensures a smooth and reliable harvest.
