The Chelsea 489 Series Power Take-Off Assembly, part number 489KLAHX-H3XK or 489KLAHXH3XK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate found on many competing designs, reducing installation time and potential leak paths. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm), matching the 442 Series rating. Output shaft is a 1-1/4" round with key. Shaft power is rated at 24 HP (500 RPM) and 48 HP (1,000 RPM). Shift is wire/cable mechanical. Internal components are common to the Chelsea 442 Series, and 27 output configurations are available across the series. Call us to confirm the correct configuration for your application.
The Chelsea 489 Series PTO is suited for utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles. The 489 Series features tapered bearings in place of needle bearings for greater load-bearing capability, and offers 27 output options including Chelsea's 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios are available across the series. For service documentation, refer to the 489 Series Parts List (HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US).
