The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-V3GZ or 489XFAHXV3GZ, is an 8-bolt PTO designed for manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing mounts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift is wire/cable mechanical. The 1-1/4" round output shaft with key delivers up to 250 lb-ft intermittent torque and 46-55 HP output power. Shaft power rates at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity. Pro Gear and Transmission sells genuine Chelsea PTOs. Call us to confirm proper fit for your application.
