Case-IH® & New Holland® Compatible Vertical Auger Top Splined Bush
Restore the drive performance of your unloading system with this premium C&M Australian-made vertical unloading auger top splined bush. Specifically engineered for Case-IH® and New Holland® flagship combine harvesters, this precision-machined component is the professional solution for repairing worn components within the primary grain handling circuit.
Manufactured in our Griffith factory, this top 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 spline stripping common in high-capacity unloading systems. 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 top spline is a critical mechanical interface. Due to the high-velocity transition of grain into the horizontal tube, this area is subject to significant vibration and abrasion. Worn splines lead to drive "chatter" and can eventually shear, causing a complete unloading stoppage. We recommend inspecting the top spline engagement for play during every preventative maintenance check to identify worn components before failure.
Upgrading to this high-performance nitride hardened bush is a strategic choice to save money on complete auger replacements. The toughened surface resists the "fretting" caused by torque cycles, keeping your grain handling system in top condition and ensuring a longer service life for the entire vertical drive assembly.
Installation Tip: Spline Alignment
When using this bush to remanufacture an auger, ensure the 24-tooth spline is perfectly concentric with the auger shaft. Use a high-pressure anti-seize lubricant on the drive splines during reassembly to prevent future abrasion and ease subsequent removals. This is the ideal time to check your unload auger elbow for thinning to ensure your unloading circuit is fully refreshed.
