CB13A UPGRADESCOOPER-BESSEMER™ CB13A TURBOCHARGERS
The CB13A is the latest design in the Cooper-Bessemer medium frame line of turbochargers. It features inboard bearings, improved compressor and turbine components, and an overall simpler design over the ET13 line, which it succeeds. This high-efficiency unit is found in both 2- and 4-cycle engine application. Through continuous refinement, compressor and turbine stage upgrades for enhanced performance and reliability have been developed for this model.
Equipping the CB13A turbocharger with a thermocouple-equipped thrust bearing provides an easy method of monitoring bearing health. The thermocouple allows for up-to-date and ongoing measurement of thrust bearing temperatures that allows an accurate synopsis of the condition of the bearing based on trending data. This is superior to previous melt out eutectic devices that only alerted after bearing failure.
CB13A Compressor Stage UpgradesBenefits› Improved turbocharger reliability through extended impeller life cycle.
› Improved vibration characteristics for smoother operation and longer life.
› Improved compressor efficiency, resulting in lowered power requirements from theexhaust turbine, i.e. more exhaust bypass margin.
› Can be performed separately or in conjunction with a turbine stage upgrade for optimalengine matching and overall turbocharger efficiency improvement.
Upgrade summary› New 5-axis milled impeller from high strength forged aluminum alloy billet for increased
strength, fin uniformity, and improved surface finish as compared to original cast design.
› Jet assist geometry redesigned to reduce stresses on impeller during engine startingresulting in increased life (2-stroke cycle engine applications).
› Balance ring incorporated into backwall of impeller provides material removal locationduring dynamic balancing operation, thus greatly reducing opportunity for stress risers inouter rim.
› Early units with “curvic coupling” method of impeller mounting converted to later“through hole” system with “cross key” drive providing more rigid fixing of impeller toturbine shaft for smoother operation and longer unit life.
› Diffuser upgrades available for compressor stage flow and efficiency optimization.
Interchangeability› External footprint of turbocharger remains unchanged, thus no existing infrastructure
modifications necessary.
› Internal components manufactured to exacting tolerances for completeinterchangeability between units of like design.

CB13A Turbine Stage UpgradesBenefits› Improved turbocharger reliability and longer run time between
overhauls through improved oil sealing and bearing temperaturemonitoring.
› Improved turbine efficiency better utilizes available exhaust gasenergy resulting in greater wastegate margin and improved hotweather performance.
› Precise turbine flow matching contributes to proper powercylinder scavenging critical for low emissions.
› Can be performed separately or in conjunction with acompressor stage upgrade for optimal engine matching andoverall turbocharger efficiency improvement.
Upgrade summary› Turbine disk and blade geometry configurations available to
maximize reaction at various exhaust flows, temperatures,and pressures.
› Variety of nozzle ring configurations available for flexibility inturbine flow matching requirements.
› “Close clearancing” of turbine blade-tips to turbine shroudreduces leak path for exhaust gases around blading, maximizingenergy capture.
