The Chelsea 489GWAHX-V3RK is an 489 Series Power Take-Off unit built for manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The 489 Series uses an integral 8-bolt one-piece cast iron housing that 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. The output shaft is a 1-1/4" round shaft with key. Intermittent torque capacity for the 489 Series ranges from 201 to 300 lb-ft. Internal parts are common to the Chelsea 442 Series, and the PTO features tapered bearings in place of needle bearings for greater load-bearing capability. Common applications within the 489 Series include utility trucks, dump trucks, and snow and ice removal equipment. Available from Pro Gear and Transmission.
