The Chelsea 489 Series Power Take-Off, part number 489XREVX-W5XE or 489XREVXW5XE, mounts directly to 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible manual transmissions. The one-piece cast iron housing eliminates the adapter plate found on many competing designs, cutting potential leak paths and reducing installation time. Shift is wire/cable mechanical. Output is through a 1-1/4" round shaft (with key option). The 489 Series delivers the same intermittent torque capacity as the 442 Series, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for stronger load handling. Call us to confirm proper fit for your transmission.
The Chelsea 489 Series is built for aerial, vocational, and municipal equipment applications including utility trucks, snow and ice removal, fire and rescue, and dump trucks. Eleven internal speed ratios and twenty-seven output options, including Chelsea's 360-degree rotatable flange, give this series broad application flexibility across multiple equipment types.
