The Chelsea 489 Series Power Take-Off, part number 489GRAHX-P3GF or 489GRAHXP3GF, is an 8-bolt mechanical shift PTO designed for most manual transmissions including Eaton Fuller, Eaton Endurant, 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. Shift type is wire/cable mechanical. Output shaft is a 1-1/4" round shaft with keyway. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and uses tapered bearings rather than needle bearings for greater load-bearing capability. Applications include utility trucks, dump trucks, aerial equipment, and snow and ice removal. Call us to confirm proper fit for your transmission and application.
