The Chelsea 489 Series Power Take-Off, part number 489XHAHX-M5XE or 489XHAHXM5XE, is an 8-bolt PTO assembly designed for manual transmissions including Eaton/Fuller, Volvo/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. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); continuous torque is derated 30% from that figure. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4" round shaft with key. Shift type is wire/cable mechanical. Internal components are common with the Chelsea 442 Series, simplifying parts sourcing.
