The Chelsea 877 Series Power Take-Off, part number 877XAFJW-M5RS or 877XAFJWM5RS, is a 10-bolt, constant-mesh PTO designed for Allison transmission applications with high torque demands and continuous-duty cycles. The output shaft is a 1-1/2" 10-spline configuration fitted with a 1410 companion flange. Continuous torque is rated up to 670 lb-ft (908 Nm); check application pages for your specific rating. Shaft power output reaches 64 HP at 500 RPM and 128 HP at 1,000 RPM. The compact housing helps reduce clearance problems during installation, and rotatable output flanges offer additional positioning flexibility.
