Abstract
A turbocharger includes a bearing housing defining an interior. The turbocharger also includes a shaft and a thrust bearing assembly disposed about the shaft. The thrust bearing assembly includes a thrust plate defining a bore configured to receive the shaft and having a first thrust surface which is integral. The thrust bearing assembly also includes a bearing having a second thrust surface which is integral. The thrust bearing assembly further includes a washer disposed between the thrust plate and the bearing. The washer has a third thrust surface which is integral, and an opposite fourth thrust surface which is integral. The third thrust surface faces the first thrust surface for engagement with the first thrust surface, and the fourth thrust surface faces the second thrust surface for engagement with the second thrust surface.
