The Chelsea 281 Series Power Take-Off Assembly, part number 281GCFJP-G8RK or 281GCFJPG8RK, is a hydraulically shifted hot-shift PTO engineered for automatic transmissions with a 10-bolt aperture, including Allison and Caterpillar transmissions. The 281 Series carries a 390 lb-ft continuous torque rating and offers nine speed ratios covering both low and high ranges. It mounts with a 10-bolt pattern and supports multiple output types including SAE B and SAE C pump flanges, ISO 7652 pump flanges, and driveline outputs. The clutch pack features steel discs 80% thicker than the previous 280 Series design, and a ductile iron bearing cap rated 117% stronger than gray iron. An o-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Markets served include fire and rescue, refuse, pumper cleaner, and truck crane applications. Call us to confirm proper fit for your transmission and output configuration.
