The Chelsea 489 Series Power Take-Off, part number 489GFAHX-W3GF or 489GFAHXW3GF, is a mechanical-shift PTO built for manual transmissions with an 8-bolt mounting aperture, including Eaton Fuller, Mack, and Tremec units. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and features tapered bearings instead of needle bearings for greater load-bearing capability. Shift type is wire/cable mechanical. Output is via a greaseable SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft, with output power rated at 46-55 HP for the series. A genuine Chelsea part, sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
