The Chelsea 897CCFJW-M3XV or 897CCFJWM3XV is a constant-mesh power take-off from the Chelsea 897 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. It uses a 10-bolt mounting configuration and positions the SAE C output flange at the rear of the transmission housing, creating clearance between the pump and the frame rail that a standard side-mounted PTO cannot provide. The one-piece main shaft eliminates input splines between the PTO body and the output, and the wet spline output interface extends pump shaft service life under continuous-duty conditions. The 897 Series suits aerial trucks, fire and rescue apparatus, refuse trucks, and truck cranes where high torque and tight clearance are both required. Call us to confirm proper fit for your specific transmission configuration.
