The Chelsea 897 Series Power Take-Off, part number 897LCFJW-M5XY or 897LCFJWM5XY, is a constant-mesh PTO engineered specifically for Allison 3000 and 4000 Series transmissions. Its 10-bolt mounting configuration positions the SAE C output flange at the rear of the transmission, moving the pump interface rearward to improve clearance between the pump and the frame rail. The one-piece main shaft eliminates the input splines found on PTO-plus-extension designs. Wet Spline output technology extends pump shaft life under demanding duty cycles. The 897 Series suits aerial trucks, fire and rescue apparatus, refuse trucks, and truck cranes where tight clearance and high continuous torque are priorities. Call us to confirm proper fit for your specific transmission configuration.
