The Chelsea 892 Series Power Take-Off, part number 892CCFJW-B3CK or 892CCFJWB3CK, is a hydraulic hot shift PTO engineered specifically for Allison 4700 Series transmissions. The 892 Series moves the pump mounting flange to the rear of the transmission, improving pump clearance in tight frame-rail installations. It mounts via a 10-bolt pattern and features an SAE C outlet flange and SAE C output shaft type. Wet spline output technology extends PTO and pump shaft life under demanding duty cycles. The one-piece main shaft eliminates input splines between the PTO body and output extension, and the clutch sits at the rear of the housing to allow the gear section to tuck tightly against the transmission. Typical applications include aerial trucks, fire and rescue trucks, refuse trucks, and truck cranes. Call us to confirm proper fit for your specific Allison 4700 configuration.
