Illustration 2. Location of components in Schwitzer Model S3B S4D and S4T turbochargers. Wear washers (1). Bearings (2). Rearing Retainers (3). Compressor end of turbocharger shaft (4). Turbine end of turbocharger shaft (5).
Other turbocharger models using wear washers will NOT necessarily be located in the same positions. See the Disassembly and Assembly Module in the appropriate Service Manual for installation instructions for a particular turbocharger. Bearing retainers (3) on ALL turbochargers should be installed with the smooth side of the retainer (snap ring) toward the bearing.
