The Chelsea 221 Series Power Take-Off, part number 221XLAHX-A3RB or 221XLAHXA3RB, is a 6-bolt mounted PTO built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. It uses a wire/cable mechanical shift and 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. The 1-1/4" round output shaft with keyway accommodates a range of pump connections. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, Hino, and others. The cast iron housing uses tapered cone output bearings for strong load capacity, and greaseable pump shafts help resist spline fretting and corrosion. Available in standard or low-profile housing configurations. Call us to confirm proper fit for your application.
The Chelsea 221 Series offers twenty-six output options including a 360-degree rotatable flange, three internal speed ratios, and eleven shift options. A self-lube option is available for transmissions with limited lubrication flow to the PTO. The series suits aerial, vocational, municipal, tow and recovery, and dump truck applications. Note: Parker Chelsea lists the 221 Series as obsolete. Pro Gear and Transmission can help you locate the right replacement or confirm availability for your unit. Call us to discuss your application.
