The Chelsea 489 Series Power Take-Off Assembly, part number 489XRAHX-P3XK or 489XRAHXP3XK, mounts directly to the 8-bolt transmission opening on most manual transmissions, including Eaton Fuller, Mack, and Tremec, without requiring a separate adapter plate. The one-piece cast iron housing keeps the mounting footprint tight and eliminates a potential leak path. The 489 Series delivers the same intermittent torque capacity as the 442 Series at up to 250 lb-ft, with shaft power of 24 HP at 500 RPM and 48 HP at 1000 RPM. The 1-1/4" round output shaft supports a keyed configuration, and the unit ships with a pressure lube designation (P) per the part number suffix. Strong tapered bearings replace needle bearings for improved load-bearing capability. Typical applications include utility trucks, dump trucks, and snow and ice removal equipment. Call us to confirm proper fit for your transmission.
