New Holland® Compatible TR99 Clean Grain Elevator Chain Kit
Restore reliable clean grain elevator performance with this C&M aftermarket clean grain elevator chain kit, built to suit the New Holland® TR99 Twin Rotor combine harvester. This complete kit includes the clean grain chain assembly, top sprocket and bottom sprocket, giving operators the key wear components required for a more complete elevator service.
Also known as the main grain chain, the clean grain elevator chain carries threshed grain up to the grain tank. Replacing the chain and sprockets together helps maintain correct chain engagement, reduces the risk of premature chain wear and supports dependable grain elevator operation during harvest.

The C&M Difference
C&M clean and return grain chain assemblies are built with practical harvest reliability in mind. The chain assemblies are assembled in Collier & Miller’s own factory in Griffith NSW using premium quality chain, and where possible, paddles are press-cut from first grade reinforced rubber sheet.
Popular chain assemblies are produced for stock, while made-to-order assemblies are normally completed quickly and shipped Australia-wide. Matching the chain with new sprockets in one kit helps reduce fitment issues and gives operators a more complete repair solution before harvest.
Expert Maintenance Review
Clean grain elevator chains operate in dusty, abrasive and high-load conditions. As the chain stretches and the sprocket teeth wear, the elevator can lose efficiency, run rough or place extra load on bearings, shafts and drive components. If the chain has visible wear, damaged paddles or poor engagement with the sprockets, replacing the chain and sprockets together is the preferred maintenance approach.
Installation Tip
Before fitting the new kit, inspect the elevator housing, bearings, shafts, tensioners and wear strips. Check that there are no sharp edges or damaged areas that could cut paddles or affect chain travel. After installation, rotate the elevator by hand where possible, confirm paddle clearance, then recheck chain tension after initial operation.
