Description
The Chelsea 221ZEAKP-A6XY or 221ZEAKPA6XY is a 6-bolt power take-off assembly from the Chelsea 221 Series, built around a cast iron housing with tapered cone output bearings for greater load-bearing capability than needle-bearing designs. Shift is wire/cable mechanical. The 1-1/4″ round output shaft with keyway delivers up to 250 lb-ft (339 Nm) intermittent torque; verify actual ratings on the application page for your transmission. Compatible transmission manufacturers include Allison, Eaton/Fuller, Volvo/Mack, and Hino. Greaseable pump shafts address spline fretting in demanding vocational cycles. A low-profile housing option is available for tight cab clearance. Call us to confirm proper fit for your application.
