Technical Notes

The S4DS006 turbo model is associated with Caterpillar heavy-duty applications, including CAT 3406 and CAT 3306B engines. Heat shields on these units protect the turbocharger from under-hood heat sources, which is critical for maintaining stable operation in earth-moving equipment like the CAT D8N and CAT 966F.

• Material & Function: The shield acts as a thermal barrier; verify material grade against your service manual.
• Mounting: Confirm bracket alignment and fastener types for your specific engine variant.
• Verification: Cross-check OEM reference 187517 with your unit's service documentation to ensure the 4W7355 part number matches your configuration.

Do not assume universal fitment across all S4DS006 applications; verify the specific engine code and production year before installation.
