The Chelsea 489 Series PTO Assembly, part number 489GLAHX-A3AF or 489GLAHXA3AF, is an air shift unit built on an 8-bolt mounting configuration. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening on most manual transmissions, including Eaton Fuller and Mack, eliminating the need for an adapter plate and reducing potential leak paths. Intermittent torque rating for the 489 Series is 201-300 lb-ft (301-400 Nm), with the same torque capacity as the 442 Series. Output is through an SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft. Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Call us to confirm proper fit for your application.
The Chelsea 489 Series is suited for aerial, vocational, and municipal equipment applications including utility trucks, snow and ice removal, fire and rescue, and dump truck and trailer use. The series offers eleven internal speed ratios and twenty-seven output options, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Strong tapered bearings replace needle bearings for greater load-bearing capability.
