Chelsea 680 Series PTO

Celsea PTO - Series 680

The Chelsea 680 Series PTO is a durable, high-performance power take-off designed for higher torque applications such as pneumatic blowers and other demanding vocational truck operations. Engineered with Parker Chelsea’s proven reliability and strength, the 680 Series delivers superior power, versatility, and long service life.

Built with a rugged cast iron housing and tapered cone bearings on the output shaft, the Chelsea 680 Series PTO offers exceptional torque capacity and durability for continuous-duty use. The input shaft features tapered roller bearings (not needle bearings) to provide greater load-bearing capability and extended service life.

Its space-saving air shift cover ensures maximum under-truck clearance, making installation easier in confined chassis environments. With 32 output options—including Chelsea’s popular 360° rotatable flange for optimal pump alignment—along with four internal speed ratios and ten shift configurations, the Chelsea 680 Series PTO provides unmatched flexibility for a wide range of applications.

For operators seeking higher torque, easier installation, and lower operating costs, the Chelsea 680 Series PTO delivers the power, performance, and reliability that Parker Chelsea is known for across the vocational truck industry.
