The Chelsea 489 Series Power Take-Off, part number 489ZADAX-A5RB or 489ZADAXA5RB, is an 8-bolt PTO assembly designed for manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit uses a wire/cable mechanical shift and delivers up to 48 HP at 1,000 RPM via a 1-1/4" round output shaft. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); check Chelsea application pages for the actual rating specific to your configuration. Internal components are common to the Chelsea 442 Series, and the kit-style design simplifies field service. Contact Pro Gear and Transmission to confirm the right configuration for your application.
