The Chelsea 660ZQDAX-V3GH or 660ZQDAXV3GH is a 660 Series Power Take-Off built for medium to heavy duty vocational applications. The 660 Series fits most popular 6-bolt manual transmissions, including those from Eaton/Fuller, Volvo, and Mack. The cast iron housing and tapered cone bearings on the output shaft give the series a torque capacity of up to 375 lb-ft intermittent, with continuous operation supported at a 30% de-rating. Tapered bearings on the input shaft, rather than needle bearings, add load-bearing capability. The space-saving air shift cover is designed to maximize clearance under the truck. Typical applications include dump trucks, aerial devices, service trucks, and snow and ice removal equipment. Call us to confirm proper fit for your specific transmission and installation.
