Important Compatibility Notes

Four vs Six Cylinder Distinction: The 4D107 is a four-cylinder engine using 6751-81 series harnesses. The 6D107 is a six-cylinder engine used in PC200-8, PC210-8, PC220-8 and PC240-8, requiring 6754-81 series harnesses. These are not interchangeable.

Emission Generation Differences: SAA4D107E-2 (Stage IIIB) and SAA4D107E-3 (Stage IV) engines have different sensors and ECM pinouts. Harnesses are not common across emission generations.

Harness Role Clarification: Engine harness, injector harness, and ECU/control module harness are separate part numbers. Ensure you order the correct harness type for your repair needs.

Frequently Asked Questions

What is this part?

An engine wiring harness for the Komatsu 4D107 and SAA4D107E four-cylinder engine family, compatible with part numbers 6751-81-8150 and 6751-81-8450.

Which machines does it fit?

PC138US-8, PC138USLC-8, PC160-8 and PW148/PW160 class machines equipped with 4D107 engines.

Will it fit a PC200-8?

No - the PC200-8 uses the six-cylinder 6D107 engine, which requires a different 6754-81 series harness.

Is this the injector harness or the main harness?

This is the engine and ECU module harness, not the separate injector harness.

Do all SAA4D107E builds use the same harness?

No, the E-2 and E-3 builds have different sensors and ECM pinouts, requiring specific harnesses for each emission generation.
