The Chelsea 489 Series Power Take-Off Assembly, part number 489GHAHX-V3RA or 489GHAHXV3RA, mounts directly to the 8-bolt transmission opening on compatible manual transmissions from Eaton/Fuller, Volvo/Mack, and Tremec, among others. The one-piece cast iron housing eliminates the adapter plate found on older designs, reducing both mounting time and potential leak paths. This unit uses a wire/cable mechanical shift and features a 1-1/4" round output shaft with keyway. The 489 Series delivers intermittent torque in the 201-300 lb-ft range, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal components are common to the Chelsea 442 Series, making service and parts sourcing straightforward. Call us to confirm proper fit for your transmission application.
The Chelsea 489 Series PTO is suited for vocational and municipal applications including utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue apparatus. The kit-style design simplifies field service, and the series shares internal components with the Chelsea 442 Series. Twenty-seven output configurations are available across the 489 Series, including a 360-degree rotatable flange option.
