Components of the 3801101 Turbocharger Repair Kit by Cummins

Heat Shield (171570)

The heat shield is a component of the turbocharger repair kit, designed to protect adjacent engine components from the high temperatures generated by the turbocharger. It maintains the integrity and longevity of the surrounding parts by acting as a thermal barrier.

Turbocharger Insulation Pad (202377)

The turbocharger insulation pad is utilized to reduce heat transfer from the turbocharger to other engine components. It ensures that the turbocharger operates within its optimal temperature range, which is vital for performance and durability.

O Ring Seals (202456 and 202457)

The O ring seals are for creating airtight and fluid-tight seals within the turbocharger assembly. They prevent leaks of oil, air, or exhaust gases, which could lead to decreased efficiency and potential damage to the turbocharger.

Rectangular Ring Seal (211375)

The rectangular ring seal is specifically designed to fit into the unique geometries found within turbocharger assemblies. It ensures a secure seal in areas where standard O rings may not fit, contributing to the overall sealing integrity of the turbocharger.

PDC Bearing Module Assembly Kit (3008143)

The PDC bearing module assembly kit is a comprehensive set of components designed to repair or replace the bearing module within the turbocharger. This kit is for restoring the turbocharger’s rotational precision and reducing friction, which directly impacts its performance and lifespan.

Turbocharger Bearing Housing (3038745)

The turbocharger bearing housing encases the bearings that allow the turbocharger’s turbine and compressor wheels to spin at high speeds. This component is vital for maintaining the alignment and support of the rotating assemblies, ensuring smooth operation and efficiency.

Turbocharger Seal Kit (3803042)

The turbocharger seal kit includes various seals and gaskets necessary to maintain the turbocharger’s internal pressures and prevent leaks. This kit is indispensable for ensuring that the turbocharger operates efficiently and reliably, with all internal components properly sealed.
