The Chelsea 660XQAHX-V3GR or 660XQAHXV3GR is a Power Take-Off unit from the Chelsea 660 Series, designed to fit most popular manual 6-bolt transmissions in medium to heavy-duty applications. The 660 Series is built around a cast iron housing with tapered cone bearings on the output shaft, delivering a torque capacity up to 375 lb-ft for demanding vocational work. Tapered bearings on the input shaft provide greater load-bearing capability than needle bearing designs. Shift options include wire/cable and mechanical actuation. Compatible output configurations span SAE A, SAE B, and ISO 7652 pump flanges, as well as driveline outputs. Typical applications include dump trucks, aerial devices, service trucks, and snow and ice removal equipment. Call us to confirm proper fit for your application.
