Product Description
549143 Pulley is precision V-belt drive pulley designed for CLAAS agricultural harvesting machines.
**Material features**: Constructed from high-grade alloy steel with precision machined belt grooves and surface hardening treatment. It has excellent rigidity and wear resistance to withstand continuous impact, heavy loads and dusty working conditions in farm fields. The smooth and accurate groove profile reduces abrasion to matched V-belts.
**Product characteristics**: This pulley is an essential power transmission component of harvester. It cooperates with V-belt to transfer rotational power and drive fan, conveying or threshing assemblies. Worn grooves, cracked pulley body or distorted hub bore will trigger belt slip, belt deviation and accelerated belt damage, resulting in power loss and unexpected machine downtime during harvest.
**Compatibility**: Direct aftermarket replacement matching OEM 549143, fully compatible with CLAAS Lexion Combine, CLAAS Tucano Combine, CLAAS Jaguar Forage Harvester, CLAAS Conspeed Corn Header. Inspect V-belt condition, calibrate coaxiality and adjust belt tension after installation. Install 549143 pulley to restore reliable belt transmission of your Claas harvester.
