KOMATSU 566-60-15361 Breather Assembly

Product Overview

The KOMATSU 566-60-15361 Breather Assembly is a Genuine Komatsu OEM hydraulic tank breather designed to equalize pressure inside the hydraulic reservoir while preventing contaminants such as dust, dirt, and moisture from entering the hydraulic system. Komatsu officially identifies this component as Breather Assembly, and it has been superseded by Part Number 566-60-15364, the current replacement.

Installed on the hydraulic oil tank, the breather allows the reservoir to “breathe” during hydraulic oil expansion and contraction caused by temperature changes and cylinder movement. By filtering incoming air, it helps maintain clean hydraulic oil, protecting pumps, valves, cylinders, and other hydraulic components from premature wear.

Technical Specifications

Note: Komatsu has not publicly published detailed OEM specifications such as filtration efficiency, airflow capacity, thread size, dimensions, or pressure relief characteristics for the 566-60-15361 Breather Assembly. Always verify compatibility using the official Komatsu Parts Catalog.

Application Information

The KOMATSU 566-60-15361 Breather Assembly is installed on the hydraulic oil tank, where it allows air to enter and exit the reservoir as hydraulic oil volume changes during machine operation. The breather filters incoming air to minimize contamination while maintaining atmospheric pressure within the hydraulic tank.

The breather is designed to withstand:

• Continuous hydraulic system operation
• Pressure fluctuations within the hydraulic reservoir
• Dusty and abrasive environments
• Moisture exposure
• Mining, quarrying, and construction applications
• Extended service intervals

Regular inspection and replacement of the breather help maintain hydraulic oil cleanliness and reduce the risk of contamination-related hydraulic component failures.
