The Chelsea 489XQITX-H3RB or 489XQITXH3RB is an 8-bolt power take-off assembly from the 489 Series, designed to mount directly to the 8-bolt aperture on compatible manual transmissions including Eaton Fuller, Volvo, Mack, and others. The one-piece cast iron housing eliminates the need for an adapter plate, reducing installation time and potential leak paths. Shift is wire/cable mechanical. The output shaft is a 1-1/4" round with key. Intermittent torque for the 489 Series is rated at 250 lb-ft (339 Nm); continuous-duty ratings should be confirmed on the application pages. Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity. Call us to confirm proper fit for your application.
