The Chelsea 489GSAHX-A5XK or 489GSAHXA5XK is a 489 Series Power Take-Off assembly designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range (250 lb-ft nominal, consistent with the 442 Series capacity) and shift is accomplished via wire/cable mechanical actuation. Output is a 1-1/4" round shaft with key. Shaft power rates at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your specific transmission.
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. The integral 8-bolt cast iron housing eliminates the adapter plate required on some competing designs, cutting both installation time and potential leak points. Tapered bearings are used in place of needle bearings for improved radial load capacity. With 27 output options and 11 internal speed ratios available across the 489 Series, this platform covers a broad range of hydraulic pump and auxiliary drive requirements.
