The Chelsea 221ZCAHX-A3XD or 221ZCAHXA3XD is a 2-gear, 6-bolt power take-off assembly from the Chelsea 221 Series, built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. Shift is wire/cable mechanical. The 1-1/4" round output shaft accepts a keyway and is supported by tapered cone bearings for greater load-bearing capability compared to needle-bearing designs. Intermittent torque rating for this series runs up to 250 lb-ft (339 Nm); check application pages for the rating specific to your installation. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. The cast iron housing is available in standard or low-profile configurations. Cross-references include 1450-221ZCAHXA3XD and CHE-221ZCAHX-A3XD. Call us to confirm proper fit for your application.
