The Chelsea 489 Series Power Take-Off Assembly, part number 489GLAHX-V5XD or 489GLAHXV5XD, is an 8-bolt PTO designed for manual transmissions including Eaton Fuller, Mack, and Tremec. Its 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. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and produces 24 HP at 500 RPM and 48 HP at 1,000 RPM through a 1-1/4" round output shaft. Wire/cable mechanical shift is standard on this unit. Internal components are common to the Chelsea 442 Series, simplifying parts sourcing and service. Call us to confirm proper fit for your transmission and application.
The Chelsea 489 Series fits a wide range of vocational applications including utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue apparatus. The 489 Series shares internal components with the Chelsea 442 Series, making cross-service straightforward for shops already stocking 442 parts. Twenty-seven output configurations are available across the series, including a 360-degree rotatable flange with a greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios and shift options are available across the series.
