The Chelsea 489 Series Power Take-Off Assembly, part number 489GRAHX-V3GK or 489GRAHXV3GK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths compared to multi-piece designs. Output is a 1-1/4" round shaft with key. Shift is wire/cable mechanical. Intermittent torque rating for the 489 Series is 201-300 lb-ft (301-400 Nm); continuous torque is de-rated 30% from that figure. Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, making service straightforward. Call us to confirm proper fit for your transmission and application.
The Chelsea 489 Series is designed for aerial, vocational and municipal, and other mobile equipment markets. Typical end-use applications include utility trucks, snow and ice removal equipment, fire and rescue vehicles, and dump trucks and trailers. The 489 Series offers up to 27 output options, including a 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, Parker Chelsea publishes the 489 Series Parts List (HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US), available through the Product Support section on Parker's site.
