The Chelsea 489ZLDAX-A6RB or 489ZLDAXA6RB is a 489 Series Power Take-Off assembly built for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift is air shift. The 489 Series delivers the same intermittent torque rating as the 442 Series, with shaft power output of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the 442 Series, simplifying service. Call us to confirm proper fit for your specific transmission and application.
