The Chelsea 892HBFJW-B5XK or 892HBFJWB5XK is a hydraulic PowerShift power take-off from the 892 Series, engineered for Allison 3000 MD and 4000 HD series transmissions using a 10-bolt mounting configuration. The SAE C (XS) output flange delivers continuous-duty torque up to 670 ft-lb and intermittent torque exceeding 501 ft-lb, with shaft power rated at 64 HP at 500 RPM and 128 HP at 1,000 RPM. The one-piece main shaft eliminates input splines between the PTO and the output extension, and wet-spline output technology reduces wear on the pump shaft in demanding duty cycles. The rear-mounted clutch and extended shaft design push the pump flange to the back of the transmission, gaining clearance between the unit and the frame rail. Suited for aerial trucks, fire and rescue, refuse, and crane applications. Call us to confirm proper fit for your application.
