Application & Compatibility
This turbine wheel is listed as a replacement application for Komatsu PC400-7 excavators equipped with SAA6D125E-3 engines. It is associated with the S400 turbocharger series and references multiple OEM numbers, including 14877100004 TW, 171924 TW, and 315425 TW. These reference numbers help confirm fitment but do not confirm universal compatibility. Buyers must verify their specific engine serial number, turbo model, and shaft diameter before ordering. Cross-check the casting number on your existing unit to ensure this part matches your requirements.
Technical Notes
Proper installation requires matching the shaft diameter and blade profile to the existing bearing housing. Inspect the old unit for foreign object damage (FOD) or excessive wear before fitting this 168146 turbine wheel. Clean the exhaust path to prevent debris from impacting the new S400 component. Verify that the shaft material and balance specifications align with your turbocharger rebuild requirements. This step ensures stable operation and prevents premature failure in Komatsu PC400-7 applications.
