The Chelsea 489GLAHX-P5RY is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing integrates the 8-bolt mounting pattern, eliminating the adapter plate that would otherwise introduce an additional leak path. The series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with shift actuation via wire/cable mechanical means. The output shaft is a round shaft with a 1-1/4" key. Pro Gear and Transmission carries this genuine Chelsea part for utility truck, dump truck, snow and ice removal, and fire and rescue applications.
