The Chelsea 489 Series Power Take-Off Assembly, part number 489GQAHX-V3XQ or 489GQAHXV3XQ, fits manual transmissions with an 8-bolt PTO mounting aperture, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. Output is a 1-1/4" round shaft with key. Shift is wire/cable mechanical. Intermittent torque rating for the 489 Series is 201-300 lb-ft (301-400 Nm); shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are shared with the Chelsea 442 Series, and the 489 uses tapered bearings in place of needle bearings for added load capacity. Call us to confirm proper fit for your specific transmission and application.
