The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-A3AF or 489XLAHXA3AF, is an 8-bolt PTO designed for 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. Shift type is wire/cable mechanical. The 1-1/4" round output shaft with key delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM or 48 HP at 1000 RPM. Tapered bearings replace needle bearings for greater load capacity. Cross-references include S-17224 and WA20-08-7119. Call us to confirm proper fit for your application.
