Additional Information
The Chelsea 680 Series is suited for aerial, dump truck, refuse, fire and rescue, snow and ice removal, blower and product pump, and service truck applications. The space-saving air shift cover provides maximum clearance under the truck, and the PTO input shaft uses tapered bearings rather than needle bearings for greater load-bearing capability. Thirty-two output options and four internal speed ratios are available across the 680 Series line. Part number 680XRAHX-A3RE is also referenced as SP680XRAHX-A3RE in some catalog systems.Parts Manual: Chelsea 680 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
