The Chelsea 287GTFJW-M3RK (also referenced as 287GTFJWM3RK) is a 10-bolt power take-off unit with pneumatic, constant-mesh shift. It mounts to Allison and other compatible transmissions using a 10-bolt (or 8-bolt) bolt pattern and delivers power through a 1-1/4-inch round output shaft with optional keyed configuration. Continuous-duty torque rating reaches up to 390 ft-lbs, with intermittent torque ratings in the 340 ft-lbs range (verify actual values on Chelsea application pages for your specific installation). Shaft power output is rated at 65 HP at 1,000 RPM. Rotatable output flanges allow clearance adjustments during installation, and a positive-stop feature protects driveline seals.
