The Chelsea 221XCAJP-W3RB or 221XCAJPW3RB is a 6-bolt, wire/cable mechanical-shift power take-off from the Chelsea 221 Series, designed for low-speed, heavy-duty vocational applications including dump trucks, tow and recovery, and aerial equipment. The 1-1/4" round output shaft with keyway delivers up to 250 lb-ft intermittent torque (verify actual rating on the application page for your configuration). Output power reaches 48 HP at 1,000 RPM. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, Hino, and other manufacturers. The cast iron housing mounts in 6-bolt positions, and greaseable pump shafts help control spline fretting over time. Call us to confirm proper fit for your transmission and application.
The Chelsea 221 Series PTO features a cast iron housing with tapered cone output shaft bearings for strong load-bearing capability under heavy-duty cycling. The 221 Series offers twenty-six output options and three internal speed ratios, making it adaptable across a broad range of vocational installations including dump trucks, tow and recovery rigs, and aerial equipment. A self-lube option is available for transmissions that have difficulty supplying lubrication to the PTO. The 360-degree rotatable flange option (available across the 221 Series) provides installation flexibility. For full application guidance, refer to the Chelsea 221 Series Owner's Manual (HY25-2221-M1_US) or contact Pro Gear and Transmission to confirm the right configuration for your truck.
