The Chelsea 877 Series Power Take-Off, part number 877XBFJP-M5RY or 877XBFJPM5RY, is a 10-bolt, constant mesh PTO designed for Allison transmissions and other compatible applications. 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 128 HP at 1,000 RPM and 64 HP at 500 RPM. The compact housing is purpose-built to reduce clearance conflicts during installation. Rotatable output flanges and Wet Spline Technology are standard features of the 877 Series. This constant mesh design suits load-sense pump applications where continuous engagement is required.
