The Chelsea 489 Series PTO Assembly, part number 489GFAHX-V3AF or 489GFAHXV3AF, is an 8-bolt unit built for manual transmissions including Eaton Fuller, Volvo, Mack, and others. Its one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and removing a potential leak path. The 489 Series delivers 250 lb-ft intermittent torque, matching the capacity of the Chelsea 442 Series, and uses tapered bearings rather than needle bearings for greater load-bearing capability. Shift is air shift. Output is via an SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft. At 500 RPM the shaft produces 24 HP; at 1000 RPM, 48 HP. Common applications include utility trucks, dump trucks, and snow and ice removal equipment. Call us to confirm proper fit for your application.
