The Chelsea 281 Series Power Take-Off Assembly, part number 281GKFJP-D5XV or 281GKFJPD5XV, is a hydraulically shifted hot-shift PTO engineered for automatic transmissions with a 10-bolt aperture, including Allison applications. The 281 Series is an evolution of the 280 Series platform, featuring a ductile iron bearing cap rated 117% stronger than gray iron, an o-ring sealing configuration between the housing and bearing cap for improved clamp load, and clutch pack steel discs that are 80% thicker than the predecessor design. The series supports continuous-duty operation and is used across fire and rescue, refuse, truck crane, and pumper cleaner applications.
