The Chelsea 489 Series Power Take-Off, part number 489GHAHX-S3XD or 489GHAHXS3XD, is an 8-bolt 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. This unit uses an air shift and features tapered bearings for greater load-bearing capability compared to needle bearing designs. Intermittent torque rating for the 489 Series runs 201 to 300 lb-ft. The 489 Series shares internal parts with the Chelsea 442 Series and suits applications including utility trucks, dump trucks, and snow and ice removal equipment.
