The Chelsea 489 Series Power Take-Off Assembly, part number 489XUBGX-W3XK or 489XUBGXW3XK, mounts directly to 8-bolt manual transmission openings without an adapter plate, eliminating a common leak path. The one-piece cast iron housing delivers the same intermittent torque capacity as the 442 Series. Shift is wire/cable mechanical. The 1-1/4" round output shaft with key suits a wide range of hydraulic pump drives. Tapered bearings replace needle bearings for greater load capacity. The 489 Series fits manual transmissions from Eaton/Fuller, Volvo/Mack, and other manufacturers, and finds use on utility trucks, dump trucks, snow and ice equipment, and fire and rescue apparatus. Call us to confirm proper fit for your application.
The Chelsea 489 Series is built for aerial, vocational, and municipal equipment as well as other mobile applications. Common vehicle uses include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue apparatus. Internal components are shared with the Chelsea 442 Series, which keeps spare parts inventory straightforward for fleets already running 442 units. The 489 Series offers eleven internal speed ratios and twenty-seven output configurations, including a 360-degree rotatable flange. For detailed parts and service information, refer to the 489 Series Parts List (HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US).
