The Chelsea 221XCAHX-A6XK or 221XCAHXA6XK is a 6-bolt power take-off assembly from the Chelsea 221 Series, designed for low-speed, heavy-duty vocational work including dump trucks, tow and recovery, and aerial equipment. Shift type is wire/cable mechanical. The 1-1/4" round output shaft with keyway delivers up to 250 lb-ft (339 Nm) intermittent torque, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, and Hino, among others. Cast iron housing with tapered cone output bearings handles greater radial loads than needle-bearing designs. A standard housing and a low-profile housing option are both available.
