Shaft Nut Replacement for CAT Earth Moving and Cummins KTTA-50-G Turbochargers

This aftermarket shaft nut serves as a replacement component for turbochargers in CAT Earth Moving equipment, Cummins KTTA-50-G engines, and Detroit Diesel Industrial applications. Designed for heavy-duty turbo repair, this part helps secure the CHRA assembly; verify engine model and physical dimensions before ordering to ensure correct fitment.

Key Specifications

This aftermarket shaft nut is engineered for heavy-duty turbocharger repair, serving as a critical fastener for the CHRA assembly. It is listed for applications including CAT Earth Moving equipment, Cummins KTTA-50-G engines, and Detroit Diesel Industrial units. Since no specific OEM reference numbers are provided, buyers must verify physical dimensions such as thread pitch and shaft diameter against their existing part. This ensures secure retention of the turbocharger shaft during high-RPM operation. Confirm exact engine model and turbo configuration before ordering to avoid fitment issues.

Application & Compatibility

Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:

• OTHER TURBOCHARGER

This shaft nut is listed for replacement applications in CAT Earth Moving equipment, Cummins KTTA-50-G engines, and Detroit Diesel Industrial units. These application paths serve as reference clues for identification; they do not confirm universal fitment across all models within these categories.

• CAT Earth Moving machinery
• Cummins KTTA-50-G engine series
• Detroit Diesel Industrial applications

Buyers must verify the specific turbocharger model, shaft diameter, and thread pitch against their existing part or engine documentation. Confirming these physical specifications ensures the replacement nut secures the CHRA assembly correctly without damaging the shaft threads during installation.

Technical Notes

This shaft nut functions as a critical fastener within the turbocharger CHRA assembly, securing the shaft during high-RPM operation. Proper torque and thread engagement are essential to prevent shaft movement or bearing damage. Since specific OEM reference numbers are not provided, buyers must verify physical dimensions against their existing part. Confirm thread pitch, shaft diameter, and overall length match the original component. This verification step ensures the replacement nut provides secure retention without damaging the turbocharger shaft threads during installation.
