The Chelsea 489ZQDAX-A6XK or 489ZQDAXA6XK is an 8-bolt Power Take-Off assembly from the Chelsea 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec without requiring an adapter plate. The one-piece cast iron housing removes a potential leak path compared to adapter-plate designs, while delivering the same 250 lb-ft intermittent torque capacity as the 442 Series. 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. Shift is wire/cable mechanical. The 489 Series carries tapered bearings in place of needle bearings for greater load capacity. Call us to confirm proper fit for your application.
The Chelsea 489 Series PTO is suited for vocational and municipal applications including utility trucks, dump truck and trailer, snow and ice removal, and fire and rescue equipment. The series offers 27 output options and 11 internal speed ratios. Internal components are shared with the Chelsea 442 Series, simplifying parts stocking and service.
