CAT 320B 320C 320D Excavator Turbocharger 49179-02300

49179-02300 Turbocharger for Caterpillar 320C 3066T Engine

The 49179-02300 turbocharger is supplied for Caterpillar excavator repair with 3066T and C6.4 diesel engine applications. It is used to restore engine boost pressure, air intake performance and stable combustion when the original turbocharger is worn, leaking oil, damaged or no longer providing normal boost response.

This page should focus on the 49179-02300 TD06H turbocharger application for CAT 320B, 320C, 320D, 321B and 321C excavator models. The old page used only the part number as the application and engine model, and it also included a generic VLS turbocharger list. Those old elements should be removed to keep the 49179-02300, 5I-8018, 3066T and C6.4 product signals clear.

Key Checking Points Before Order

Turbochargers should not be confirmed only by excavator model. The same machine model may use different engine versions or turbocharger specifications, so the old turbocharger plate number and engine model should be checked before quotation.

Part Number Check: Confirm 49179-02300 from the old turbocharger plate, supplier record or removed sample.

Cross Number Check: If the buyer provides 5I-8018, confirm it together with engine model and turbo photos.

Engine Check: Confirm whether the engine is Caterpillar 3066T or C6.4.

Machine Check: Confirm CAT 320B, 320C, 320D, 321B or 321C application if the turbo is ordered by machine model.

Sample Check: Provide photos of the old turbocharger from the compressor side, turbine side, actuator side and nameplate side.

Turbocharger Replacement Notes

Before replacing the 49179-02300 turbocharger, the engine air intake system, exhaust manifold, oil feed line, oil return line and air filter condition should be checked. Turbocharger failure can be caused by oil starvation, dirty oil, air restriction, exhaust leakage or foreign object damage.

After installation, the lubrication system should be primed before engine start. The oil line should be clean, the air intake pipe should be free from debris, and the engine should be checked for abnormal smoke, oil leakage, boost pressure loss or unusual noise during testing.
