Case-IH® & New Holland® Compatible Vertical Auger Bottom Splined Bush
Restore the drive of your unloading system with this premium C&M Australian-made vertical unloading auger bottom splined bush. Specifically engineered for Case-IH® and New Holland® flagship combines, this precision-machined component is the professional solution for repairing worn components in the primary grain handling circuit.
Manufactured in our Griffith factory, this bush is the same high-specification unit used in our C&M extended wear vertical augers. Featuring a nitride hardened surface, this bush provides superior abrasion resistance and prevents the "stripping" common in standard splined couplings. This high-strength refurbishment part allows you to remanufacture your existing auger, keeping your machine in top condition for a significantly longer service life.

Expert Maintenance Review
The vertical unloading auger bottom spline is a critical wear point within the grain handling assembly. Constant engagement and high material volumes lead to abrasion thinning of the spline teeth, which can cause the auger to slip or "spin out" under load. We recommend inspecting the spline engagement during every preventative maintenance check to identify worn components before they cause a complete unloading failure.
Upgrading to this nitride hardened C&M bush is a strategic choice to save money on expensive complete auger replacements. The hardened surface maintains its profile far longer than standard steel, ensuring a high-strength mechanical bond with the drive shaft and keeping your unloading system in top condition for multiple harvests.
Installation Tip: Weld Concentricity
When using this bush to remanufacture an existing auger, ensure the bush is perfectly centered and square to the auger tube before welding. Any misalignment will cause vibration and rapid abrasion thinning of the splines. This is the ideal time to check your vertical unload auger flighting for wear to ensure your grain handling system is restored to full capacity.
