The Chelsea 680 Series Power Take-Off, part number 680XHAHX-V3GK or 680XHAHXV3GK, is a medium- to heavy-duty PTO built around an 8-bolt mounting configuration. The 680 Series uses a cast iron housing with tapered cone bearings on both the output shaft and input shaft, providing strong load-bearing capability suited to higher-torque applications such as pneumatic blowers. The series covers most manual transmission applications featuring an 8-bolt PTO aperture, with specific fitment for Eaton Fuller transmissions and a deep-mount housing option for Mack applications. Output options across the 680 Series include SAE A, SAE B, and driveline configurations. Continuous operation is supported with a 30% de-rating.
