The Chelsea 892HAFJW-B5XK or 892HAFJWB5XK is a Series 892 power take-off assembly built for Allison 3000 MD and 4000 HD series transmissions. It mounts via a 10-bolt pattern and shifts hydraulically through Chelsea PowerShift, making it a direct-drive PTO for demanding continuous-duty applications. The SAE C ("XS") output shaft and wet-spline lubrication design extend shaft and pump service life. Continuous-duty torque is rated up to 670 ft-lb (908 Nm); intermittent torque is rated above 501 ft-lb. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. The extended output shaft provides additional clearance between the PTO and the driven pump. Call us to confirm proper fit for your specific Allison application.
