The Chelsea 489 Series Power Take-Off Assembly, part number 489XQAHX-V6XK or 489XQAHXV6XK, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and others. Its one-piece cast iron housing eliminates the need for an adapter plate, removing a common leak path. The 489 Series delivers the same intermittent torque capacity as the 442 Series (250 lb-ft / 339 Nm); this unit uses air shift. Output is an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your transmission and application.
