The one-piece cast iron housing eliminates a potential leak path and delivers the same torque capacity as the Chelsea 442 Series. Intermittent torque rating for the 489 Series runs 201 to 300 lb-ft (301 to 400 Nm). Shift type is wire/cable mechanical. Output shaft is a 1-1/4-inch round shaft with keyway. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your specific transmission and application.
