6502-13-2003 KTR130-11F Turbocharger for Komatsu S6D155-4 Engine

6502-13-2003 KTR130-11F Turbocharger for Komatsu S6D155-4 Engine

The 6502-13-2003 KTR130-11F turbocharger is supplied for Komatsu S6D155-4 and 6D155 diesel engine applications. It is commonly checked for heavy-duty Komatsu dozer and generator repair, including D155A-2, D155C-1 and EG300 series applications. This turbocharger helps restore boost pressure, combustion air supply and engine output when the old turbocharger is worn, leaking oil or no longer producing stable boost.

This replacement turbocharger should be matched by the old turbocharger number, turbo model, engine model and removed sample. Since turbocharger housing, flange and oil pipe positions can differ by engine version and equipment application, the old turbocharger tag and sample photos should be checked before order confirmation.

Main Part Number and Ref Cross

The main part number is 6502-13-2003. Ref Cross numbers such as 6502-13-2002, 6502-13-2001, 6502-13-2004, 319319, 07071303-5 and 6502132003 can be used for inquiry matching. Final confirmation should still be made by checking the old turbocharger nameplate, engine model and removed sample photos before shipment.

Engine Model: Komatsu S6D155-4 / 6D155 diesel engine

Main Application: Komatsu D155A-2 / D155C-1 dozer

Related Application: D150A-1, D155A-1, EG300-1, EG300-2 and related S6D155-4 engine applications

Application Matching Notes

For Komatsu S6D155-4 and 6D155 engine applications, this turbocharger should be confirmed by engine plate, old turbocharger number and sample comparison. Machine model alone is not enough for final matching because turbocharger configuration can vary by engine version, production year and previous replacement history.

Engine Check: Confirm Komatsu S6D155-4 or related 6D155 engine model from the engine plate.

Machine Check: Confirm D155A-2, D155C-1, D150A-1, D155A-1, EG300 or the actual equipment model.

Turbo Tag Check: Look for 6502-13-2003, 6502-13-2002, 319319, 07071303-5 or KTR130-11F on the old turbocharger record.

Sample Check: Compare compressor housing, turbine housing, mounting flange, oil inlet and oil return position.

Final Matching Rule: Use old turbo nameplate, engine model and removed sample photos before quotation.

Common Replacement Conditions

This KTR130-11F turbocharger is commonly replaced when the engine has weak boost, black smoke, slow response under load, abnormal turbo noise, oil leakage or excessive shaft clearance. Before installing a new turbocharger, the intake, exhaust and lubrication systems should be checked to prevent repeat failure.

Weak Boost or Black Smoke: Check the air filter, intake pipe, compressor wheel and exhaust side connection for blockage, leakage or damage.

Oil Leakage: Check the oil feed line, oil return line and crankcase ventilation. A blocked oil return line can cause oil leakage at the turbocharger seal area.

Abnormal Turbo Noise: Check shaft clearance, bearing wear, wheel contact marks and signs of contaminated oil before replacing the turbocharger.

Inspection Before Installation

Before replacing the 6502-13-2003 turbocharger, inspect the air filter, intake pipe, exhaust manifold, oil feed line, oil return line and exhaust side connection. Large Komatsu 6D155 engines require stable oil supply and clean air intake; a blocked oil line or damaged air filter can quickly damage a new turbocharger.

During installation, add clean engine oil into the turbocharger oil inlet and rotate the compressor wheel by hand before the first start. After installation, run the engine at low speed first and check for oil leakage, abnormal turbo noise, black smoke, blue smoke, weak boost or exhaust leakage before returning the machine to heavy-load work.
