Chelsea part number 897LGFJW-M5XY or 897LGFJWM5XY is a 897 Series Power Take-Off designed to mount on Allison 3000 and 4000 Series transmissions. The 10-bolt constant-mesh design positions the SAE C output flange at the rear of the transmission, improving pump clearance compared to a conventional side-mount arrangement. A one-piece main shaft eliminates the input splines between the PTO body and the output extension. The wet-spline output extends PTO and pump shaft service life under continuous-duty hydraulic demand. Applications include aerial trucks, fire and rescue units, refuse trucks, and truck cranes. Call Pro Gear and Transmission to confirm proper fit for your specific transmission configuration.
