The Chelsea 489 Series Power Take-Off, part number 489XQAHX-V5GK or 489XQAHXV5GK, mounts directly to 8-bolt manual transmission openings found on Eaton/Fuller, Volvo/Mack, and other compatible units. The one-piece cast iron housing eliminates the need for an adapter plate, cutting down potential leak paths. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm); shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The greaseable SAE B 2 or 4-bolt flange output has a 7/8" 13-tooth SAE B shaft, and the air shift keeps the setup straightforward. Tapered bearings replace needle bearings for improved load capacity. Internal components are common to the Chelsea 442 Series, making parts support practical. Call us to confirm fit for your specific transmission and application.
The Chelsea 489 Series fits utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue apparatus. Twenty-seven output options are available across the series, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios are available within the series. For detailed parts information, refer to the 489 Series Parts List (HY25-2442-M1_US) or the Chelsea Service Manual (HY25-6489-M1/US).
