524XTDDX-H-XY Chelsea PTO Assembly

The Chelsea 524 Series Power Take-Off assembly, part number 524XTDDX-H-XY or 524XTDDXHXY, is a rear-mount PTO designed for Daimler DT12 transmission applications. As a 524 Series unit, it mounts via the rear aperture of compatible transmissions to help eliminate clearance problems that forward-mount PTOs can create. The series features a compact two-gear housing, pneumatic shift integrated directly into the housing, and a DIN 5462 output shaft flange. Three gear ratios are available across the 524 Series to match varying application speeds. Input adapters for this series also cover ZF, Mack mDrive, Volvo I-Shift, and Eaton Endurant transmissions. Pro Gear and Transmission carries this genuine Chelsea part for aerial, refuse, fire, and vocational truck applications.
