CASE-IH® Compatible Outer Unloading Auger Tube (118" / 2998mm)
Restore the operation of your grain handling system with this premium aftermarket outer unloading auger tube. Specifically engineered for Case-IH® mid-series Axial-Flow combines, this high-performance tube is the professional solution for repairing worn components in the primary discharge circuit.
This 118-inch (2998mm) outer tube is a precision-manufactured replacement designed to bolt directly to the inner auger tube assembly. By addressing thinned-out or dented housings, you provide a high-strength foundation for high-capacity grain transition. This extended wear solution ensures your unloading system remains in top condition, maintaining smooth flow and preventing the grain turbulence that accelerates wear on internal auger flighting.

Expert Maintenance Review
The outer unloading auger tube is a high-duty friction zone. Over time, the discharge end of the tube suffers from extreme internal abrasion thinning, which can lead to structural failure or "blow-outs" during high-speed unloading. We recommend inspecting the internal wall thickness during every preventative maintenance check to identify worn components before they fail mid-harvest.
Upgrading to this high-performance replacement tube is a strategic choice to save money on long-term grain handling costs. A structurally sound tube ensures the outer unloading auger flighting remains perfectly centered, providing a longer service life for the entire unloading assembly and keeping your machine in top condition.
Installation Tip: Check the Swivel
When installing the new 1317899C4 outer tube, always inspect the unload auger swivel assembly and flange bolts for wear. A secure, high-strength connection at the pivot point is essential for safe operation. This is the ideal time to check your discharge spout and flighting to ensure maximum unloading throughput.
