MacDon® & CNH Compatible Flame Hardened Center Drum Drive Sprocket (37T)
Maintain reliable power transmission with this premium C&M Australian-made center feed drum drive sprocket. Specifically engineered for MacDon®, Case IH®, and New Holland® draper platforms, this 37-tooth sprocket is a high-performance replacement designed to withstand the high-torque demands of center feed systems.
Manufactured in our Griffith factory, each sprocket is flame hardened to increase the surface density of the teeth, significantly reducing the rate of wear from metal-on-metal chain contact. This extended wear solution ensures a longer service life for your drive assembly, keeping your intake system in top condition throughout the harvest season.

Expert Maintenance Review
The center drum drive sprocket is responsible for driving the entire feed drum assembly. Over time, the tooth profile can become "hooked" or thinned, which causes the drive chain to stretch or ride unevenly. We recommend inspecting the tooth sharpness and chain engagement during every preventative maintenance check to avoid sudden drive failure.
Upgrading to a flame hardened C&M sprocket is a high-performance choice. The hardened teeth maintain their profile much longer than standard untreated sprockets, ensuring your feeding system stays in top condition. This extended wear component prevents mid-harvest downtime and ensures a high-strength connection between your drive motor and the center drum.
Maintenance Tip: Inspect Your Drive Chain
When installing a new 37T drive sprocket, always inspect the condition of your 60 pitch drive chain. A worn or elongated chain will rapidly destroy the teeth on a new sprocket, even a flame-hardened one. Replacing the chain and sprocket together provides the most reliable setup and maximises the service life of your entire feed system.
