6136813112, 6136-81-3112 AIR COMPRESSOR ASSY KOMATSU

Heavy-Duty Air Compressor Assembly for Komatsu S6D105 Engine Applications

The 6136813112, 6136-81-3112 AIR COMPRESSOR ASSY KOMATSU is an engine-related air compressor assembly used in Komatsu heavy machinery applications, especially machines equipped with the S6D105 engine family. Public parts references identify 6136-81-3112 as an AIR COMPRESSOR ASS’Y, while commercial spare parts listings describe it as an air compressor assembly for Komatsu S6D105 engine applications.

For heavy machinery owners, this part is not a simple accessory. A compressor assembly supports the machine’s air supply system and contributes to dependable operation in equipment where pneumatic support, braking-related air supply, or engine-mounted air compression is required. When the compressor becomes weak, noisy, worn, or unable to build proper air pressure, machine performance and safety-related operating confidence can be affected. That is why buyers searching for 6136813112 or 6136-81-3112 usually need an exact replacement rather than a universal compressor.

At 3GEN Export, we supply 6136813112, 6136-81-3112 AIR COMPRESSOR ASSY KOMATSU as an OEM supplier solution for global heavy machinery buyers. We deliver all over the world in 5 working days, helping workshops, resellers, contractors, and fleet owners reduce downtime and restore equipment faster.

What Is 6136813112, 6136-81-3112 AIR COMPRESSOR ASSY KOMATSU?

The 6136813112, 6136-81-3112 AIR COMPRESSOR ASSY KOMATSU is a compressor assembly designed for Komatsu engine applications. Public sources connect this part number with the S6D105-1 engine family, and one commercial listing describes it directly as AIR COMPRESSOR ASSY 6136-81-3112 – S6D105 ENGINE.

Another spare parts supplier lists the part as 6136-81-3112 / 6136813112 Air Compressor Ass’y Komatsu 105 Engine, placing it in the Engine Parts category. This supports the correct product positioning: it should be described as an engine air compressor assembly for Komatsu machinery, not as a general hydraulic, electrical, or cabin component.

The product image also visually matches this classification. It shows a compact engine-mounted compressor form with a cast body, shaft connection area, upper head section, air ports, mounting holes, and bolted structure. This is consistent with the type of compressor assembly used in heavy diesel equipment.

Why This Komatsu Air Compressor Matters

A Komatsu air compressor has a critical job: it must produce stable compressed air for the systems that depend on it. In heavy equipment, air supply reliability is important because machines work under vibration, dust, changing temperatures, long operating hours, and high-load duty cycles. A weak compressor can reduce system efficiency, increase downtime, and create maintenance problems that affect the entire machine.

The 6136813112, 6136-81-3112 AIR COMPRESSOR ASSY KOMATSU is especially important because it is associated with Komatsu S6D105 engine applications. Public listings from different suppliers repeatedly connect 6136-81-3112 with S6D105 or Komatsu 105 engine wording, which gives strong support for engine-family-based product targeting.

In real jobsite conditions, this part helps support:

Stable Air Generation

The air compressor assembly helps create the compressed air needed by machine systems. A properly working unit supports consistent air output and helps the equipment operate with better reliability.

Engine-Mounted System Dependability

Because this component is tied to Komatsu engine applications, it must work properly under heat, vibration, and continuous duty. This makes material quality, machining accuracy, and correct fitment especially important.

Reduced Downtime

When an air compressor fails, the machine may become unsuitable for safe or efficient work. Replacing the failed unit with the correct 6136-81-3112 compressor helps return the equipment to service faster.

Better Maintenance Planning

Using the correct part number helps workshops avoid mismatch. Buyers can search both 6136813112 and 6136-81-3112, making it easier to confirm the right compressor before ordering.

Important Fitment Note

Final compatibility should always be confirmed by exact part number, engine model, machine model, and serial number before ordering. Public sources strongly support the S6D105 engine connection, and several sources connect this part with Komatsu grader applications. However, machine fitment can vary by serial range, market version, and engine arrangement.

Product Design and Working Characteristics

The 6136813112, 6136-81-3112 AIR COMPRESSOR ASSY KOMATSU is built as a compact compressor assembly for engine-mounted operation. The product image shows a cast housing, upper compressor head, visible ports, bolted mounting surfaces, and a drive shaft area. This type of construction is typical for compressors installed in heavy diesel equipment.

The working environment for this part is demanding. A Komatsu grader or heavy machine may operate in dust, mud, heat, cold, vibration, and long daily shifts. The air compressor must continue to produce stable air output while mounted close to the engine, where temperature and vibration are constant.

A 3GEN Export listing describes the part as built with alloy steel and aluminum components, designed for S6D105 engine compatibility, and made to deliver air compression for braking systems, pneumatic controls, and related engine functions. This is seller-provided product detail, but it aligns with the expected role of an engine air compressor assembly.

Key Benefits of 6136813112, 6136-81-3112 AIR COMPRESSOR ASSY KOMATSU

Supports Reliable Air Supply

A properly working compressor helps maintain compressed air generation for systems that depend on air pressure. This supports machine reliability and reduces the risk of pressure-related downtime.

Designed for Komatsu S6D105 Applications

The public fitment data repeatedly connects this part with the S6D105 engine family, making it suitable for buyers who need a compressor specifically matched to Komatsu 105 engine applications.

Helps Restore Machine Readiness

When an air compressor fails, the machine may not be ready for full-duty work. Replacing the assembly can help restore proper air-system operation and reduce delays in field service.

Strong Fit for Grader Maintenance

Public sources connect this part with several Komatsu grader models, including GD505A, GD521A, GD605A, GD611A, GD621R, GD623A, GD661A, and GD663A. This makes it especially relevant for grader fleets and road maintenance operations.

Useful for Export and Workshop Stock

Because 6136-81-3112 appears across multiple supplier catalogs and marketplaces, it is a recognized replacement part in the global Komatsu spare parts market. Workshops and resellers can list it confidently with both part number formats.

Common Reasons for Replacement

Low Air Pressure

If the machine cannot build or maintain proper air pressure, the compressor assembly may need inspection or replacement.

Noise or Internal Wear

A worn compressor can produce abnormal sound, vibration, or reduced output. Heavy-duty machines often operate for long hours, making internal wear a normal replacement reason.

Leakage Around Compressor Body or Head

Sealing issues can affect air output and overall compressor efficiency. If repair is not practical, full assembly replacement may be preferred.

Fleet Refurbishment

Graders and Komatsu machines prepared for resale, export, or continued service often require compressor replacement as part of engine accessory maintenance.

Preventive Maintenance

For older machines using S6D105 engines, replacing the compressor before complete failure can help avoid unexpected downtime.
