The Chelsea 281GDKVP-B5RK or 281GDKVPB5RK is a hydraulically shifted, hot-shift power take-off built on the 281 Series platform, designed for automatic transmissions with a 10-bolt aperture, commonly found on Allison and Caterpillar applications. This PTO delivers a single, continuous duty torque rating and supports nine speed ratios covering both low and high ranges. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load and resists the vibrational effects of modern engine designs. Rotatable, cast-iron flanges reduce interference issues at the pump, and a Positive Stop for driveline outputs eliminates oil seal damage from coupling. This part also cross-references with 280GDKVP-B5RK or 280GDKVPB5RK. Call us to confirm proper fit for your application.
