The Chelsea 489DLMBX-56XD or 489DLMBX56XD is a Power Take-Off assembly from Chelsea's 489 Series, designed for manual transmissions with an 8-bolt PTO mounting aperture. The integral 8-bolt cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating an extra potential leak path. This series uses a wire/cable mechanical shift and features a 1-1/4" round keyed output shaft. Internal tapered bearings provide greater load-bearing capability compared to needle-bearing designs. Internal components are common to the Chelsea 442 Series. Applications include utility trucks, dump trucks, and vocational equipment. Call us to confirm proper fit for your transmission and application.
