The Chelsea 892CAFJW-B3CZ or 892CAFJWB3CZ is a hydraulic hot-shift power take-off from the Chelsea 892 Series, engineered specifically for Allison 4700 Series transmissions. The 892 Series relocates the pump mounting flange to the rear of the transmission, improving pump clearance where frame rail space is tight. It mounts via a 10-bolt pattern and uses an SAE C outlet flange with an SAE C output shaft. Wet Spline Technology on the output extends PTO and pump shaft service life in high-demand conditions. The unit is a single-piece main shaft design, eliminating the input splines between the PTO body and output extension. Common applications include aerial trucks, fire and rescue apparatus, refuse trucks, and truck cranes. Call us to confirm proper fit for your specific transmission configuration.
