The Chelsea 680GHAHX-V3GF or 680GHAHXV3GF is a medium- to heavy-duty 8-bolt power take-off from the Chelsea 680 Series, built primarily for Eaton/Fuller manual transmissions and available with a deep-mount housing option for Mack applications. The 680 Series carries the part under NMFC code 128520 (Hydraulic PTOs, Pumps, Motors), reflecting its hydraulic-circuit role. A cast iron housing and tapered cone bearings on the output shaft deliver the higher torque capacity the series is engineered for, making it a fit for pneumatic blower and pump-driven vocational work. The series supports wire/cable and mechanical shift types and offers 360-degree rotatable flange output. Pro Gear and Transmission sells this genuine Chelsea part.
