The Chelsea 489 Series Power Take-Off, part number 489XHAHX-S3RK or 489XHAHXS3RK, is an 8-bolt mechanical shift PTO built for most manual transmissions including Eaton Fuller, 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. Tapered bearings replace needle bearings for greater load-bearing capability. The 489 Series delivers an intermittent torque rating of 201-300 lb-ft and shaft output of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Output is via a 1-1/4 inch round shaft with key. Internal parts are common to the Chelsea 442 Series. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
