The Chelsea 877XFFJP-M3XV or 877XFFJPM3XV is a constant-mesh power take-off from the Chelsea 877 Series, designed for Allison transmissions with a 10-bolt mounting configuration. The output shaft is a 1-1/2" 10-tooth spline with a 1410 companion flange. Continuous torque is rated at 670 lb-ft (908 Nm), and intermittent torque exceeds 501 lb-ft. Shaft power reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. The compact housing reduces installation clearance issues, and rotatable output flanges give further flexibility during mounting. Wet Spline Technology is built in to extend the service life of both the PTO and the pump shaft. Common applications within the 877 Series include refuse trucks, aerial equipment, snow and ice vehicles, and fire and rescue trucks. Call us to confirm proper fit for your application.
