The Chelsea 489 Series Power Take-Off Assembly, part number 489GQAHX-V5XQ or 489GQAHXV5XQ, is a wire/cable mechanical shift PTO built on an 8-bolt mounting pattern that bolts directly to the transmission opening without an adapter plate, removing a potential leak path. The one-piece cast iron housing delivers the same intermittent torque capacity as the Chelsea 442 Series, rated at 250 lb-ft (339 Nm) intermittent. Output shaft is a 1-1/4" round configuration. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 489 Series fits most manual transmissions with an 8-bolt aperture, including Eaton/Fuller and Volvo/Mack applications. Call us to confirm proper fit for your specific transmission.
The Chelsea 489 Series is designed for vocational and municipal equipment, aerial applications, utility trucks, snow and ice removal equipment, fire and rescue vehicles, and dump trucks and trailers. The integral 8-bolt cast iron housing eliminates the need for an adapter plate, reducing potential leak paths compared to multi-piece designs. Tapered output bearings replace needle bearings for greater load-bearing capability. Twenty-seven output options are available across the 489 Series, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios and shift options are offered across the series. For service information, refer to Chelsea 489 Series Parts List HY25-2442-M1_US or Service Manual HY25-6489-M1/US.
