The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round with key, and this configuration includes pressure lubrication (P). Intermittent torque capacity for the 489 Series is 201-300 lb-ft; shaft power output is 24 HP at 500 RPM and 48 HP at 1000 RPM. Internal parts are common to the Chelsea 442 Series.
