Upgrading the Honda Impeller-to-Stator Bearing

Torque-converter rebuilders have been reporting Honda bearing failures in increasing numbers. The bearing failures have been from different locations within the converters and have been reported in most of the Honda and Acura models. The most common of the failures has been the bearing between the impeller and stator in the larger-diameter converters. In all converters, the bearing in this location carries most of the thrust load when the vehicle is accelerating, and it is typically the first bearing to fail. Because the larger-diameter converters are used in the larger, higher-torque V-6 applications, the thrust loads on this bearing are even greater.
