The Chelsea 892CBFJW-D3CZ or 892CBFJWD3CZ is a hydraulic hot shift power take-off built for Allison 4700 Series transmissions. The 892 Series mounts via a 10-bolt pattern and positions the SAE C output flange at the rear of the transmission, improving pump clearance without the need for an extension unit. The main shaft is one-piece, eliminating input splines between the PTO body and the output. Wet Spline Technology is incorporated at the output to extend both PTO and pump shaft life under demanding duty cycles. Input gear designator FJ confirms fitment to Allison 3000 MD and 4000 HD Series as well as the 4700 Series. The 892 Series suits aerial trucks, fire and rescue equipment, truck cranes, and refuse applications where high torque and tight pump clearance are both required. Call us to confirm proper fit for your specific transmission configuration.
