The Chelsea 489ZLCRX-A4XK is a 489 Series Power Take-Off built for 8-bolt manual transmission openings on applications including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating an extra potential leak path. Shift type is wire/cable mechanical. The 489 Series delivers intermittent torque of 201-300 lb-ft (301-400 Nm) and shaft power of 24 HP at 500 RPM or 48 HP at 1000 RPM. Output is via a round shaft with 1-1/4" key. Internal parts are common to the Chelsea 442 Series, and tapered bearings replace needle bearings for greater load capacity. Available from Pro Gear and Transmission.

Additional Information
The Chelsea 489 Series shares internal components with the 442 Series, giving it comparable torque capacity at 250 lb-ft continuous (de-rate 30% for continuous-duty applications). Twenty-seven output options are available across the 489 Series, including a 360-degree rotatable flange with greaseable shaft to help reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios are offered across the series. Typical markets include utility trucks, aerial equipment, snow and ice removal, fire and rescue, and dump truck operations.Parts Manual: Chelsea 489 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
