Case-IH® Compatible Incline Delivery Auger
Restore peak unloading efficiency with this premium C&M Australian-made incline delivery auger. Specifically engineered for Case-IH® early model mid-series combine harvesters, this high-performance auger is designed to meet the rigorous demands of high-volume grain handling.
Manufactured in our Griffith factory, this auger features 10" diameter flighting constructed from heavy-duty 6mm G250 flighting. A critical enhancement is the nitride hardened female 16-spline hub, which provides a long lasting coupling that resists the rounding and stripping common in standard units. This extra thick extended wear design ensures a longer service life and keeps your machine in top condition during the harvest.

Expert Maintenance Review
The incline delivery auger is a high-duty component within the unloading system. Over time, the leading edge of the 10" flighting can thin due to abrasion, and the drive splines can develop "slop" from constant torque cycles. We recommend inspecting the spline engagement and checking the flighting thickness at the intake point during every preventative maintenance check.
Upgrading to this nitride hardened C&M auger is a high-performance choice to **save money** on future drivetrain repairs. The hardened spline prevents the drive shaft from "spinning" inside the hub under heavy load, ensuring your grain handling system remains reliable and providing a significantly longer service life for the entire unloading assembly.
Installation Tip: Inspect the Drive Shaft
When installing a new incline auger, always inspect the 16-spline drive shaft for wear or twisting. A worn shaft will place uneven load on the new nitride hardened hub, leading to premature failure. Ensuring a tight, high-strength fit between these components is vital for a smooth, high-speed unloading process.
