Additional Information
The Chelsea 680 Series is a recognized workhorse for higher-torque vocational applications including pneumatic blowers, dump trucks, aerial equipment, refuse vehicles, and fire and rescue apparatus. The space-saving air shift cover design is engineered to maximize clearance under the truck. Tapered input shaft bearings - rather than needle bearings - provide greater load-bearing capability. The 680 Series offers thirty-two output options and four internal speed ratios. Typical markets include aerial, vocational, and municipal applications.For service and rebuild reference, Parker Chelsea publishes the 680 Series Parts List (HY25-2660-M1_US) and the 340/348/442/447/489/660/680/823/863/880 Series Owner's Manual.
