Additional Information
The Chelsea 680 Series is suited for aerial, fire and rescue, dump truck, refuse, snow and ice removal, service truck, and blower and product pump applications. The PTO input shaft uses tapered bearings rather than needle bearings for greater load-bearing capability. Chelsea's space-saving air shift cover is designed to maximize clearance under the truck. The 360-degree rotatable flange option available across the 680 Series provides additional flexibility for pump fitment.Parts Manual: Chelsea 680 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
