Product Description

CUMMINS Piston component 5579186

1. Product Overview

CUMMINS Piston component 5579186 is listed under source title “KIT ENGINE PISTON”. It is classified for Batch 4 as piston component within the combustion and power conversion system. The source record does not establish an exact engine model. Confirm the complete engine model, serial number, arrangement, and installed reference before ordering.

2. Function and Operating Principle

A piston receives combustion pressure and transfers force through the piston pin and connecting rod to the crankshaft. Its crown, ring grooves, skirt, cooling features, and weight must match the engine's combustion and cylinder design.

The piston reciprocates inside the cylinder while the ring pack seals combustion gas, controls oil, and transfers heat. Clearances and component matching change with engine model, bore, piston version, and overhaul specification.

4. Typical Signs That Inspection May Be Required

ObservationPossible significance
Scuffing, scoring, or skirt wearMay involve lubrication, cooling, clearance, contamination, or overheating.
Broken ring lands or crown damageRequires investigation of combustion, injection, cooling, and foreign material.
High blow-by or oil consumptionCan involve rings, liner condition, piston damage, or ventilation faults.
Cylinder knock or imbalanceRequires measurement and diagnosis of the complete cylinder assembly.

These observations are inspection triggers rather than a confirmed diagnosis. Evaluate the complete engine system and follow the applicable manufacturer service information.

5. Inspection and Replacement Guidance

  • Inspect the crown, grooves, skirt, pin bore, rings, liner, and cooling passages.
  • Measure clearances and protrusion only by the engine manual.
  • Match piston version, weight group, bore, rings, pin, and liner.
  • Confirm engine serial number and overhaul configuration.

6. Information Required Before Ordering

  • Complete engine or equipment model.
  • Engine serial number and arrangement or configuration number.
  • Installed part reference and clear photographs of the identification label.
  • Installation position and related assembly information.

Compatibility notice: Verify 5579186 against serial-number-specific parts documentation before purchase or installation. Do not select the component by appearance or part-number similarity alone.
