The Chelsea 892CFFJW-B3CF or 892CFFJWB3CF is a hydraulic hot-shift power take-off from the Chelsea 892 Series, designed specifically for Allison 4700 Series transmissions. The 892 Series moves the PTO and pump mounting flange to the rear of the transmission, improving pump clearance in tight frame-rail installations. It uses a 10-bolt mounting pattern with an SAE C outlet flange and SAE C output shaft type. A one-piece main shaft eliminates the input splines between the PTO and output extension, while the rear-located clutch lets the housing and gear section tuck tightly against the transmission. Wet Spline technology on the output extends PTO and pump shaft life under demanding duty cycles. Common applications include aerial trucks, fire and rescue trucks, refuse trucks, and truck cranes. Call us to confirm proper fit for your specific transmission configuration.
