The Chelsea 680GQAHX-V3GF or 680GQAHXV3GF is a 680 Series Power Take-Off built for medium- and heavy-duty applications requiring an 8-bolt transmission mount. It shifts via wire/cable mechanical actuation and delivers output shaft power of 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. The 1-1/4" round output shaft (with key) suits higher-torque demands such as pneumatic blowers. The series carries an intermittent torque rating of 301-400 lb-ft (check application pages for actual torque ratings). The cast iron housing and tapered cone bearings on the output shaft support long service life. A deep-mount housing option accommodates Mack transmission installations, and the unit is also compatible with Eaton/Fuller and other 8-bolt transmission applications.
