NP-DLLA152S354N406 Diesel Nozzle Replacing 6136-11-3120

105015-4060 Diesel Injector Nozzle

The 105015-4060 is a diesel injector nozzle tip used in selected Komatsu S6D105 and 6D105 engine fuel injection systems. Its nozzle identification is NP-DLLA152S354N406, with 9432610065 and 6136-11-3120 used as common checking references.

This listing is for the injector nozzle element shown in the product images. It is not a complete fuel injector assembly and does not include the nozzle holder, spring or other injector body components.

Part Number and Application Check

The strongest machine reference for this nozzle is the Komatsu PC200-3 with an S6D105 or 6D105 engine. Other machines using the same engine family may have different injector and nozzle configurations, so the engine model alone should not be used as the final fitment reference.

Before ordering, compare the marking on the removed nozzle with 105015-4060 or NP-DLLA152S354N406. The nozzle type, spray specification, injector holder and engine fuel-system configuration should match the original unit.

Installation and Calibration

Injector nozzles should be installed in a clean diesel fuel injection workshop. The injector holder should be inspected before assembly, and the completed injector must be tested for opening pressure, spray pattern and leakage according to the applicable engine specification.

Contaminated fuel, damaged injector holders or incorrect calibration can cause poor atomization, excessive smoke, unstable engine operation and premature nozzle failure. Replace the fuel filters and clean the fuel system if contamination is found.

FAQ

Is this a complete fuel injector?

No. This product is the diesel injector nozzle tip only. The injector holder and complete injector assembly are not included.

What should I compare before ordering?

Compare the marking on the old nozzle, the injector holder configuration and the engine model. Clear photos of the old nozzle and injector holder are recommended.

Does the injector require calibration after installation?

Yes. The assembled injector should be tested for opening pressure, spray pattern and leakage by a qualified diesel fuel injection workshop.
