The Chelsea 221 Series Power Take-Off, part number 221XLDAX-V3XK or 221XLDAXV3XK, is a 6-bolt mounted PTO built for low-speed, heavy-duty service on vocational trucks including dump trucks, tow and recovery units, and aerial equipment. It uses a wire/cable mechanical shift and features a 1-1/4" round output shaft with keyway. Intermittent torque is rated up to 250 lb-ft (339 Nm); confirm actual ratings against the Chelsea application pages for your specific installation. Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Compatible transmissions span Allison, Eaton/Fuller, Hino, Volvo/Mack, and others. The cast iron housing is available in standard or low-profile configurations. Call us to confirm proper fit for your application.
The Chelsea 221 Series PTO uses tapered cone output bearings rather than needle bearings, providing greater load-bearing capability in demanding vocational applications. Three internal speed ratios are available across the series, and the design supports a self-lube option for transmissions that have difficulty delivering lubrication to the PTO mounting pad. The 360-degree rotatable flange option (where applicable by configuration) aids installation flexibility. Typical applications include dump trucks, tow and recovery vehicles, and aerial equipment. Contact Pro Gear and Transmission to confirm the correct configuration for your transmission and chassis.
