This 4LF654 core is listed for Caterpillar CAT F-654 and CAT D379B engine applications. These application clues serve as reference points for verification; they do not confirm universal fitment. Buyers should verify the specific engine code, production year, and existing turbo configuration before ordering. Confirm that the core dimensions and flange profile match your current assembly. Cross-check any available OEM reference numbers against your maintenance records. If the application involves a specific turbo variant, verify the actuator and cooling requirements separately.

Technical Notes

The 4LF654 core is a mechanical assembly containing the turbine wheel, compressor wheel, and bearing housing. No OEM reference numbers are supplied for this part, so buyers must verify fitment using the engine code and existing turbo configuration. Confirm that the core dimensions, shaft alignment, and flange profile match your current assembly. Check the bearing housing for wear and ensure the turbine and compressor wheels are balanced. Verify that the gasket kit and V-band clamps are compatible with the 4LF654 core before installation.
