The Chelsea 489ZHDAX-A5AF or 489ZHDAXA5AF is a Power Take-Off unit from Chelsea's 489 Series, designed for manual transmissions with an 8-bolt PTO mounting aperture. The integral 8-bolt one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Compatible manual transmissions include Eaton Fuller, Mack, and Tremec. The 489 Series uses wire/cable mechanical shift and delivers intermittent torque in the 201-300 lb-ft range. Output shaft type is a round shaft with 1-1/4" key. Tapered bearings, rather than needle bearings, provide greater load-bearing capability. Call us to confirm proper fit for your application.
