CLAAS® Compatible Stainless Steel Beater Cap
Keep your threshing system in top condition with this premium C&M Australian-made stainless steel beater cap. Specifically engineered for Claas® and Cat® Lexion combine harvesters, this high-performance cap is the professional solution for repairing worn components within the product feeding and threshing assemblies.
Manufactured in our Griffith factory from heavy-duty 304-grade stainless steel, this cap provides superior abrasion resistance compared to standard carbon steel units. A unique property of this high-strength stainless steel is its ability to work-harden during operation, creating a slick, toughened surface that resists pitting. This extended wear construction ensures a consistently smooth crop transition and a significantly longer service life over multiple seasons.

Expert Maintenance Review
The beater cap is a critical wear point in the product feeding functional area. Worn or pitted caps often cause crop "snagging," which leads to uneven material flow and increased power consumption. We recommend inspecting the beater caps for abrasion thinning and surface irregularities during every preventative maintenance check to identify worn components before they impact threshing efficiency.
Upgrading to this high-performance stainless steel cap is a strategic choice to save money on long-term maintenance. The polished transition surface maintains its integrity far longer than painted steel, keeping your threshing assembly in top condition and ensuring maximum throughput during the harvest window.
Installation Tip: Secure Fastening
When installing your new 663157 high-strength caps, ensure the beater drum surface is clean and level. Using the supplied A4-grade stainless bolts ensures a secure mechanical bond that resists vibration and corrosion. This is the ideal time to check your feeder house chains and impeller wear plates to ensure total efficiency in your product feeding system.
