The Chelsea 524 Series rear-mount PTO assembly, part number 524XTDDX-P-XK or 524XTDDXPXK, is built specifically for Daimler DT12 transmission applications. This unit mounts to the rear aperture of compatible transmissions, helping eliminate clearance issues that forward-mount PTOs can create in tight installations. The 524 Series features a pneumatic shift integrated directly into the compact PTO housing, an ISO 7653 80mm x 80mm mounting interface, and a DIN 5462 output shaft flange. Three gear ratios are available across the series. The design includes a sealed bayonet connector for the indicator switch and supports direct-mount pump output flanges. Call us to confirm proper fit for your specific truck and transmission configuration.
