Case-IH® Compatible Feeder Drum Tube Assembly (Support Rings)
Maintain consistent performance with this premium C&M Australian-made feeder drum tube assembly. Specifically engineered as an aftermarket feeder idle roller for Case-IH® Flagship Axial-Flow combines, this high-performance component is designed for machines equipped with standard U-bar feeder chains.
Manufactured in our Griffith factory, this heavy-duty assembly features precision-welded chain support rings. These rings are essential for machines in the 120, 230, and early 240 series, as they provide the necessary support for U-bar slats. By providing a stable, high-strength foundation for the chain, this assembly ensures a longer service life for your product feeding system.

Expert Maintenance Review
The feeder idle roller is a primary wear point where the feeder chain transitions from the header into the combine. On U-bar equipped machines, the support rings are vital; if these rings wear down or become uneven, the slats can twist or "chatter," leading to inconsistent feeding and potential slat breakage. We recommend inspecting the ring profile during every preventative maintenance check.
Upgrading to this high-performance C&M drum is a strategic way to **save money** on downstream threshing components. A true-running, balanced drum keeps your product feeding system in top condition, preventing the vibration that can lead to premature failure of the feeder house bearings and drive sprockets.
Installation Tip: Chain Verification
Before installing this drum, verify your feeder chain type. If you have upgraded to a heavy cast-bar chain, you must use the "ringless" drum version (PN 51552615). For U-bar chains, ensure the support rings align perfectly with the chain links to ensure a high-strength, smooth material flow into the rotor.
