The Chelsea 489 Series Power Take-Off, part number 489ZADAX-A5XQ or 489ZADAXA5XQ, is an 8-bolt mount PTO designed to bolt directly to compatible manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates the adapter plate leak path while delivering the same 250 lb-ft intermittent torque capacity as the Chelsea 442 Series. Output shaft is a 1-1/4" round with key. Shift is accomplished via wire/cable mechanical actuation. Output power runs 46-55 HP, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered output bearings replace needle bearings for improved load-bearing capability. Call us to confirm proper fit for your application.
The Chelsea 489 Series PTO fits vocational and municipal equipment applications including utility trucks, snow and ice removal equipment, fire and rescue vehicles, and dump trucks. The series offers 27 output options and 11 internal speed ratios. For detailed parts information, refer to the 489 Series Parts List (HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US) available through Parker's Product Support section.
