The Chelsea 489 Series PTO Assembly, part number 489XSAHX-V3AF or 489XSAHXV3AF, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate required on many competing designs, removing a potential leak path. This unit uses air shift (installation kit not included); the 489 Series delivers up to 48 HP at 1,000 RPM. The 489 Series carries the same 250 lb-ft intermittent torque rating as the 442 Series, with tapered bearings instead of needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series, keeping service inventory simple. Contact Pro Gear and Transmission to confirm proper fit for your transmission.
