Additional Information
The Chelsea 680 Series is suited for aerial, dump truck, fire and rescue, refuse, snow and ice removal, service truck, and blower and product pump applications. The space-saving air shift cover is designed to provide maximum clearance under the truck. The PTO input shaft uses tapered bearings rather than needle bearings for greater load-bearing capability. Four internal speed ratios and up to thirty-two output options, including a 360-degree rotatable flange, make the 680 Series adaptable across a wide range of vocational equipment installations.Parts Manual: Chelsea 680 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
