The Chelsea 489 Series Power Take-Off Assembly, part number 489XQAHX-V3GK or 489XQAHXV3GK, mounts directly to an 8-bolt transmission opening without an adapter plate, eliminating a common leak path. The one-piece cast iron housing delivers up to 250 lb-ft intermittent torque, matching the torque capacity of the 442 Series. Shift is wire/cable mechanical, and the output shaft is a 1-1/4" round with key. The 489 Series is compatible with Eaton Fuller, Volvo/Mack, and other manual transmissions including Eaton Endurant and Tremec. Shaft power rates at 24 HP at 500 RPM and 48 HP at 1,000 RPM. For help confirming proper fitment for your transmission and application, call Pro Gear and Transmission.
The Chelsea 489 Series is suited for aerial, vocational, and municipal equipment applications including utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles. The tapered bearing design provides greater load-bearing capability compared to needle bearing configurations. Twenty-seven output options are available across the series, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios are offered within the 489 Series platform.
