Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • Cummins 4BT and 6BT diesel engines with matching H1C turbocharger
  • Marine and industrial engine installations, subject to turbo specification

Product Overview

An H1C turbocharger uses exhaust energy to compress incoming air. A damaged bearing, leaking seal or worn turbine can reduce boost, cause abnormal noise and contribute to oil entering the intake or exhaust. Confirm that the engine actually uses this turbo configuration before replacing it.

Key Features & Performance

  • Turbocharger assembly
  • turbo model H1C

OE / Reference Numbers

  • 3538723
  • 3802870

Common Reasons for Replacement

  • Low boost under load
  • Whistling or grinding from a worn turbo
  • Excessive oil at turbo housings

Fitment & Installation Notes

Match the turbo identification plate, exhaust flange, compressor outlet, wastegate arrangement and oil connections; engine family alone does not establish fit.
