Product FAQ

This kit is a reference application for Isuzu 4JB1TC, 4JG2T, and 4FC-1T engines, as well as Sumitomo S380 and Yanmar TNE84T-VM. Verify your specific engine code and turbo configuration before ordering.

Check the thread pitch on the existing turbocharger studs and nuts against the NN139922 kit components. Ensure the pitch matches the engine block and turbo housing specifications to prevent cross-threading during reassembly.

Inspect the V-band clamp included in the NN139922 kit to ensure the diameter and profile match the compressor and turbine housing flanges of the RHB5 turbocharger. Mismatched clamps can cause leaks or improper sealing.

Verify that the O-rings in the NN139922 kit are made of heat-resistant material suitable for the operating temperatures of the Isuzu or Sumitomo engine. Confirm the size matches the oil and water port dimensions on the turbo housing.

Compatibility Verify part number NN139922, turbo model RHB5, engine code (e.g., Isuzu 4JB1TC, 4JG2T, Sumitomo S380), vehicle application, production year, and OEM reference numbers before ordering. Confirm specific turbo configuration and connection types for your application.
