The Chelsea 897RDFJW-M5AF or 897RDFJWM5AF is a constant-engagement power take-off from the Chelsea 897 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting design positions the SAE C output flange at the rear of the transmission, moving the pump interface rearward to maximize clearance between the pump and the frame rail. Wet Spline Technology on the output shaft reduces wear in high-demand operating cycles, extending both PTO and pump shaft service life. The one-piece main shaft eliminates the input splines found in extension-type designs. Typical applications include aerial trucks, fire and rescue, truck cranes, refuse trucks, and snow and ice equipment. Call us to confirm proper fit for your specific transmission configuration.
