CASE-IH® Compatible Feeder House Sprocket (1-1/2" Hex)

Keep your product feeding system in top condition with this premium Australian-made feeder house sprocket. Specifically engineered for Case IH® mid-series Axial-Flow combines, this extended wear component ensures smooth operation and a longer life for your feeder house assembly.

Manufactured by C&M in our Griffith factory, this sprocket is a precision-machined direct-fit replacement for the front feeder house drive. By replacing worn or "hooked" sprockets with this grade 1045 billet assembly, you maintain precise feeder chain timing and protect your feeder house driveline from unnecessary vibration.

New 2026 High-Performance Design

Our latest 2026 generation sprockets feature a specialised relief cut at the base of each tooth. This critical engineering upgrade assists with minimising "chain jump" by allowing straw and debris to escape from the bottom of the tooth profile rather than compacting. This ensures consistent chain engagement in heavy crop conditions and contributes to a significantly longer service life for your entire feeder house assembly.

Expert Maintenance Review

To keep your product feeding system in top condition, we recommend replacing these sprockets in complete timed sets.

The new 2026 relief cut design is specifically intended to solve issues in heavy straw, allowing for an extended wear cycle by reducing the stress caused by debris buildup. Standard preventative maintenance suggests that installing new chains on worn sprockets will significantly reduce the chain's longer service life.
