The Chelsea 489ZRITX-A5AF or 489ZRITXA5AF is a 489 Series Power Take-Off assembly designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening and delivers the same intermittent torque capacity as the 442 Series at 250 lb-ft (339 Nm). Shaft power rates at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4" round with key. Shift is wire/cable mechanical. Internal components are common to the 442 Series, keeping service parts readily available. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 489 Series PTO is suited for aerial, vocational, and municipal equipment applications including utility trucks, snow and ice removal equipment, fire and rescue vehicles, and dump trucks and trailers. The series offers eleven internal speed ratios and shift options, plus twenty-seven output configurations including Chelsea's 360-degree rotatable flange. Tapered bearings replace needle bearings for greater load-bearing capability. Kit-style design simplifies service, and internal parts are shared with the 442 Series.
