The Chelsea 281GGFJP-E5XD or 281GGFJPE5XD is a hydraulically shifted, hot-shift Power Take-Off from Chelsea's 281 Series, designed for automatic transmissions with a 10-bolt aperture commonly found on Allison transmissions. It mounts via a 10-bolt configuration and operates in continuous duty. The 281 Series delivers nine speed ratios spanning low and high ranges, and the ductile iron bearing cap is 117% stronger than the gray iron cap used on earlier units. An o-ring sealing configuration between the housing and bearing cap improves clamp load and cuts vibrational effects. The Enhanced Clutch Pack uses steel discs 80% thicker than the previous generation to resist premature tooth wear. Applications include fire and rescue, truck cranes, pumper cleaner, and refuse trucks. Call us to confirm proper fit for your specific transmission and application.
