Product FAQ

This unit references OEM numbers 4043229 and 4955920. Use these numbers to help confirm fitment for your specific Cummins B engine application.

Inspect the turbine housing flange and compare the seal groove dimensions against your original unit or service manual. Verify the specific seal kit required for the HY35 model before installation.

Confirm that the compressor wheel oil slinger matches the bearing housing design of your existing turbo. Mismatched slingers can affect lubrication and cause premature failure in Cummins B applications.

Check if the replacement includes a heat shield and verify its material matches your vehicle's exhaust routing requirements. Ensure the shield fits securely to prevent heat damage to nearby components.
