6136813111, 6136-81-3111 AIR COMPRESSOR ASSY KOMATSU

Reliable Air Supply for Komatsu S6D105 Engine Applications

The 6136813111, 6136-81-3111 AIR COMPRESSOR ASSY KOMATSU is a Komatsu engine-mounted air compressor assembly used in S6D105-family applications. Public parts references identify it as AIR COMPRESSOR ASS’Y, while aftermarket technical listings describe it with a 153 cc displacement and 40 mm stroke for S6D105 engine use. Seller listings also connect it to Komatsu WA320 applications and other equipment built around the same engine family.

For heavy equipment owners, this is not a minor accessory. An air compressor assembly helps generate the compressed air required by machine systems that depend on stable pneumatic support. On Komatsu equipment, a faulty compressor can lead to poor air supply performance, slower system response, and more downtime during demanding work cycles. That is why buyers usually search for 6136813111 or 6136-81-3111 when they need a direct, application-matched replacement rather than a generic compressor. This product should therefore be presented as a serious service part for S6D105-based Komatsu machines.

What Is 6136813111, 6136-81-3111 AIR COMPRESSOR ASSY KOMATSU?

The 6136813111, 6136-81-3111 AIR COMPRESSOR ASSY KOMATSU is a compressor assembly designed for Komatsu diesel engine applications, especially within the S6D105 family. Public catalog references list the official part name as AIR COMPRESSOR ASS’Y, and additional technical seller data identifies the compressor as an S6D105 unit with 153 cc displacement and 40 mm stroke. The product image also matches the general form of an engine-mounted reciprocating air compressor, with a cast housing, drive shaft nose, and upper compressor head section consistent with working compressor assemblies used in heavy equipment.

This matters because heavy machinery buyers often search by a very exact number, not only by general category. Some type 6136813111 without dashes, others search 6136-81-3111 exactly as shown in parts books or repair records. A strong product page should use both versions naturally so the listing performs better in Google, Search GPT, and internal marketplace searches. The same public seller page also shows multiple search-tag variations around WA320, S6D105 engine air compressor, and Komatsu compressor language, which supports the importance of using both part number styles and function-based phrases in the copy.

Why This Air Compressor Assembly Matters

An engine air compressor assembly is essential wherever the machine depends on compressed air for supporting pneumatic functions. Public sources classify 6136-81-3111 under air compressor and braking-system related categories, which indicates it is part of the machine’s working air supply system rather than a cooling or fuel-delivery component. When this kind of compressor becomes weak, worn, or damaged, the machine can lose reliable air generation and overall working confidence drops.

In practical field use, that means the 6136813111, 6136-81-3111 AIR COMPRESSOR ASSY KOMATSU supports dependable machine operation by maintaining compressed air output for systems that require it. This is especially important on construction and earthmoving equipment that works in harsh environments, where dust, vibration, temperature change, and long operating hours place constant stress on engine-mounted accessories. Seller descriptions consistently position this compressor for heavy-duty Komatsu service, which fits the real-world expectations of contractors and maintenance teams.

AIR COMPRESSOR ASS’Y, (SEE FIG.621)

Engine family

S6D105 / 6D105-related Komatsu engine applications are the clearest public fitment signals for this part. Public parts references tie the part to 6D105-1F and S6D105-1G engine applications, while seller listings also describe it directly as an S6D105 engine air compressor.

Compressor technical data

Aftermarket technical references list the compressor at 153 cc with a 40 mm stroke for S6D105 use. These figures come from technical seller listings rather than a Komatsu factory data sheet, so they are best treated as practical market specifications for replacement sourcing.

Weight in KG

Public catalog data from 777parts shows 0.000 kg, which is clearly a placeholder and not a practical shipping value. Two commercial seller sources list the compressor at 10 kg, which is the most useful figure for a product page and shipping estimate. For website listing purposes, 10 kg is the strongest practical weight reference now available.

Compatible KOMATSU Models for 6136813111, 6136-81-3111 AIR COMPRESSOR ASSY KOMATSU

Public model data for this part comes from a mix of catalog references and seller listings, and the fitment is best understood in two layers.

First, catalog references tie the part to 6D105-1F (S/N 12218-UP) and S6D105-1G (S/N 12124-UP) applications rather than giving a single clean machine list. That suggests the safest technical approach is always to verify by engine code, part number, and serial range.

Second, seller listings name several Komatsu machines that use S6D105-based installations. The most specific seller page clearly states Used for Komatsu WA320, while another seller list names PC200-6, PC220-6, D65EX-12, and WA380-3as compatible model examples. Because these seller fitment lists are not identical, they should be used as guidance rather than absolute proof for every serial range.

Fitment note

The safest buying method is to confirm 6136-81-3111, the engine family, and the machine serial number before ordering. Public sources agree on the S6D105 / 6D105 connection, but the named machine lists vary by seller. That is common in heavy machinery parts sales, especially when one part appears across multiple equipment families using related engines.

Design and Working Characteristics

The product image shows a compact, engine-driven compressor assembly with a lower mounting body, central cylinder section, and finned head area. That layout is consistent with a reciprocating compressor used in diesel-powered construction equipment. While public sources do not provide a full factory drawing, the visible form and the published technical references support describing this part as a heavy-duty air compressor assembly for Komatsu S6D105 engine service.

Built for continuous machine service

Heavy equipment engine accessories work under constant vibration and temperature fluctuation. A compressor like 6136813111 must maintain dependable air generation across long working shifts, whether the machine is loading material, moving earth, or supporting roadwork. Seller descriptions consistently present the part as suitable for construction, mining, and industrial applications, which matches the expected duty cycle of Komatsu equipment in the field.

Supports system reliability

Because this part belongs to the machine’s air-compression side, it affects more than one moment of operation. A healthy compressor assembly helps maintain stable air delivery and reduces the risk of system weakness caused by compressor wear, leakage, or inefficient compression. This is a grounded inference from the part’s documented role as an air compressor assembly in braking-system or pneumatic-related categories.

Practical service relevance

The existence of related repair-kit listings on seller pages indicates that this compressor family is actively serviced in the replacement market. That is important for workshops, because it shows the part is recognized, repairable, and relevant enough to have established aftermarket support.

Typical Reasons Buyers Replace 6136813111, 6136-81-3111 AIR COMPRESSOR ASSY KOMATSU

Most buyers do not look for this part unless there is a real machine issue.
