The Chelsea 489 Series Power Take-Off Assembly, part number 489XHAHX-S5SQ or 489XHAHXS5SQ, is a wire/cable mechanical shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing mounts directly to the transmission, no adapter plate required, which reduces potential leak paths compared to multi-piece designs. Output shaft is a 1-1/4" round with key. Intermittent torque capacity matches the 442 Series at 250 lb-ft (339 Nm), with output power rated at 46-55 HP (31-40 kW). Shaft power measures 24 HP at 500 RPM and 48 HP at 1000 RPM. Compatible transmissions include Eaton Fuller, Volvo/Mack, and Tremec. Call us to confirm proper fit for your application.
The Chelsea 489 Series PTO 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 489 Series parts manual (HY25-2442-M1_US) and service manual (HY25-6489-M1/US) are available through Parker Chelsea's Product Support section for detailed application and service information.
