The Chelsea 489 Series Power Take-Off, part number 489ZRDAX-V3XK or 489ZRDAXV3XK, is a wire/cable mechanical-shift PTO built for manual transmissions with an 8-bolt mounting aperture, including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft output of 24 HP at 500 RPM or 48 HP at 1,000 RPM. The round 1-1/4-inch keyed output shaft is a standard feature of this series. Typical applications include utility trucks, dump trucks, and snow and ice removal equipment. Call us to confirm proper fit for your specific transmission and application.

Additional Information
The Chelsea 489 Series shares internal parts with the proven 442 Series, giving it the same 250 lb-ft torque capacity in a one-piece housing that bolts straight to 8-bolt manual transmission openings. Strong tapered bearings replace needle bearings for greater load-bearing capability. The series offers 27 output options and 11 internal speed ratios, including Chelsea's 360-degree rotatable flange with a greaseable shaft to reduce pump shaft spline fretting and corrosion. Common service applications include aerial equipment, vocational and municipal trucks, fire and rescue, and snow and ice removal.
