The Chelsea 680XHAHX-V3XK or 680XHAHXV3XK is a 680 Series Power Take-Off built for medium- to heavy-duty manual transmission applications with an 8-bolt PTO aperture. The 680 Series uses a cast iron housing with tapered cone bearings on the output shaft for durability under demanding, higher-torque work such as pneumatic blowers. The series covers Eaton Fuller and Mack transmissions, with a deep-mount housing option for Mack applications. Four internal speed ratios and ten shift options give this PTO broad versatility across aerial, dump truck, refuse, fire and rescue, and service truck applications. Call us to confirm proper fit for your specific transmission and application.
