The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-W5XD or 489XFAHXW5XD, is an 8-bolt PTO designed to mount directly to most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate, eliminating a potential leak path. The one-piece cast iron housing delivers the same intermittent torque capacity as the 442 Series. Shift actuation is wire/cable mechanical. Output is via a 1-1/4" round shaft (with key), rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 489 Series features strong tapered bearings rather than needle bearings for greater load capacity, and the kit-style design simplifies field service. Available with greaseable output options. A genuine Chelsea part, sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
