Replacement Internal Hub For Cross Auger Repair Kit
Maintain your C&M modified cross auger system with this premium C&M Australian-made internal hub. Specifically designed for MacDon® and Case-IH® draper fronts already fitted with the C&M 6" cross auger tube repair kit, this hub provides the critical mounting point for the replaceable 1" hex bush.
Manufactured in our Griffith factory, this component is an extended wear solution that allows for rapid servicing of your auger drive. By providing a secure, high-strength mounting flange, this internal hub ensures that future bush replacements are a simple bolt-in task, keeping your grain handling system in top condition without the need for additional welding once the initial repair kit is installed.

Expert Maintenance Review
The internal hub is the backbone of the modular C&M cross auger system. While the hex bush itself is the primary wear item, the hub provides the stable high-strength platform required for positive torque transfer. We recommend inspecting the hub mounting holes for thread integrity and the weld circumference for cracks during every preventative maintenance check.
Utilising this extended wear hub design is a high-performance choice for large-scale operations. It eliminates the downtime traditionally associated with cutting and re-welding original auger tubes. This modular approach ensures your feeding system maintains its alignment and remains in top condition for a significantly longer service life.
Installation Tip: Weld Integrity
When welding this replacement internal hub into the auger tube, ensure the tube interior is free from scale and residue to achieve maximum weld penetration. A high-performance, 360-degree weld is essential to handle the torsional stress of high-volume crop intake. Once installed, verify that the bolt-in hex bush seats perfectly flush against the hub flange.
