The Chelsea 892HCFJW-B5XS or 892HCFJWB5XS is a hydraulic PowerShift power take-off from the Chelsea 892 Series, engineered for Allison 3000 MD and 4000 HD series transmissions. It mounts via a 10-bolt pattern and delivers a continuous-duty torque rating up to 670 ft-lb, with intermittent torque exceeding 501 lb-ft. The SAE C ("XS") extended output shaft moves the pump mounting flange to the rear of the transmission, creating additional clearance where tight frame-rail packaging is critical. A one-piece main shaft eliminates input splines between the PTO body and the output extension. Wet Spline output technology reduces wear on the pump shaft in demanding, continuous-duty applications. Shaft power reaches 128 HP at 1,000 RPM. Suited for aerial trucks, fire and rescue rigs, refuse trucks, and truck cranes. Call us to confirm proper fit for your application.
The 892 Series fits between the transmission and the frame rail, locating the pump output to the rear of the transmission for adequate clearance in tight installations. Unlike a PTO-plus-extension arrangement, the 892 is a single unit with a one-piece shaft. The clutch is positioned at the rear of the PTO housing so the gear section tucks tightly to the transmission. The unit can be ordered for transmissions equipped with or without a cooler, a retarder, or both. Common applications include aerial trucks, fire and rescue apparatus, pumper cleaners, truck cranes, and refuse trucks operating in snow and ice or other demanding duty cycles.
