Winzor TP-1315: Upper Gearbox for Brushcutter Efficiency

The Winzor upper gear reducer TP-1315 is a critical spare part that acts as a vital link between the engine and the drive system. This engine-mounted gearbox housing ensures stable torque transmission, allowing you to handle dense grass effectively. Its robust construction and precision assembly significantly reduce vibration, increasing operational comfort and protecting other mechanisms from damage. Winzor products are known for their enhanced bearings, which prevent overheating during long working sessions in any garden environment. This complete set includes the clutch housing and pads, making it ready for instant professional installation.

Rear Reducer Compatibility for 28mm Tube and 9 Spline Shaft

Model TP-1315 is specifically designed for 28mm diameter tubes and 9 spline internal shafts. This component is an ideal fit for popular BC430 and BC520 series brushcutters (43cc to 52cc). If your tool makes grinding noises or the blade fails to spin, it often indicates worn internal gears or damaged splines. Replacing the worn unit with a new Winzor TP-1315 upper gearbox will restore your tool's original power. During installation, we recommend using lithium grease on shaft ends to extend the life of the splines. Choose reliable Winzor components for durability and professional-grade performance.
