Case-IH® Compatible Extended Wear Vertical Unloading Auger (24T)
Ensure maximum grain discharge speed with this premium C&M Australian-made vertical unloading auger. Specifically engineered for Case-IH® Flagship and high-capacity New Holland® combine harvesters, this extended wear component is fitted with 24-spline hubs and is designed for heavy-duty grain handling.
Manufactured in our Griffith factory using abrasion-resistant EH400 flighting, this auger is built to outperform standard OEM units. The drive hubs are nitride hardened to prevent spline stripping, while the entire assembly is dynamically balanced to reduce vibration. This high-strength construction ensures a longer service life, saving you significant downtime and maintenance costs.

Expert Maintenance Review
The vertical unloading auger is a critical high-wear component, particularly at the intake and the transition to the horizontal auger. Standard flighting often thins rapidly at the edges, leading to a significant drop in unloading speed. We recommend inspecting the flighting thickness and the 24-spline hub for internal wear during every preventative maintenance cycle.
Upgrading to an EH400 extended wear auger is a high-performance choice. The nitride hardened splines prevent the common issue of the hub rounding out under heavy load, while the balanced flighting keeps your unloading system in top condition. This reinforced design ensures your machine maintains peak unloading capacity even in abrasive or high-moisture crops.
Installation Tip: Check the Gearbox
When replacing the vertical auger, always inspect the vertical gearcase and drive splines. A worn gearbox output shaft can damage the new nitride hardened hub, leading to premature failure. Replacing the gearcase seals and checking the oil level at the same time ensures a high-strength drive connection for the entire harvest.
