The Chelsea 877 Series Power Take-Off, part number 877XGFJP-M3RS or 877XGFJPM3RS, is a constant-mesh, 10-bolt PTO engineered for Allison transmissions. 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), with intermittent torque capacity exceeding 501 lb-ft. Shaft power reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. Constant-mesh design suits load-sense pump applications that do not require mid-cycle disengagement. The compact housing reduces clearance demands, rotatable output flanges allow installation flexibility, and Wet Spline Technology extends service life for both the PTO and pump shaft. Common applications include refuse trucks, aerial units, snow and ice equipment, and fire and rescue vehicles. Call us to confirm proper fit for your transmission and installation.
