The Chelsea 489 Series Power Take-Off Assembly, part number 489XXITX-A3XK or 489XXITXA3XK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate found on older designs, reducing potential leak paths and cutting installation time. Intermittent torque rating for the 489 Series is 201-300 lb-ft (301-400 Nm), with output power of 46-55 HP (31-40 kW). Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft accepts a key. Internal components are shared with the Chelsea 442 Series, making parts sourcing straightforward. Available with no-pressure lube (X) or pressure lube (P) configurations. 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. Eleven internal speed ratios are available across the 489 Series lineup, and the series offers 27 output configurations including Chelsea's 360-degree rotatable flange with greaseable shaft - designed to reduce pump shaft spline fretting and corrosion. Tapered bearings replace needle bearings for greater load-bearing capability. Internal components are interchangeable with the Chelsea 442 Series, which simplifies parts management for fleets running both series.
