The Chelsea 489 Series Power Take-Off Assembly, part number 489ZRDAX-A5RB or 489ZRDAXA5RB, mounts directly to an 8-bolt transmission opening without an adapter plate, eliminating a potential leak path versus two-piece housings. The one-piece cast iron housing delivers the same intermittent torque capacity as the 442 Series. Shift is wire/cable mechanical, and the output shaft is a 1-1/4" round with key. The 489 Series fits most manual transmissions including Eaton Fuller, Mack, and Tremec. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common with the 442 Series, simplifying parts stocking. 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 vehicles. The 489 Series supports eleven internal speed ratios, and the series offers twenty-seven output options including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline wear and corrosion. For service documentation, Parker Chelsea publishes the 489 Series Parts List (HY25-2442-M1_US) and a dedicated Service Manual (HY25-6489-M1/US) covering this series.
