The Chelsea 489 Series PTO Assembly, part number 489XQAHX-A5SQ or 489XQAHXA5SQ, is an 8-bolt power take-off 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 adapter plate and its potential leak path. Shift type is wire/cable mechanical. The 1-1/4" round output shaft (with key) delivers up to 250 lb-ft intermittent torque and shaft power of 24 HP at 500 RPM or 48 HP at 1000 RPM. Tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
