23B7031331, 23B-70-31331 GUIDE KOMATSU

The 23B7031331, 23B-70-31331 GUIDE KOMATSU is a grader wear-guide component used in the work equipment area of selected Komatsu motor graders. Public parts-catalog references place this number in either CIRCLE SUPPORT MOUNTING PARTS or Circle and Blade Support Adjuster, which immediately tells buyers this is not a random bronze strip, but a control-and-guidance wear part in the circle support system of the machine.

That placement matters because the circle and blade support area is one of the most heavily loaded working zones on a grader. When the moldboard is angling, cutting, correcting slope, or holding line over long shifts, the support structure has to stay controlled, smooth, and dimensionally stable. A guide in this section helps manage movement, carry sliding contact, and reduce damaging metal-to-metal wear in the mounting system. The catalog position of 23B-70-31331 strongly supports that function.

From the uploaded images, this part appears as a straight, bronze-colored guide strip with a flanged wear profile. The shape is simple, but that simplicity is exactly what makes the part important: it is designed to provide a controlled sliding surface, maintain fit, and absorb wear in a location where alignment and movement quality matter every day. The bronze-style finish shown in the images also matches aftermarket listings that describe this number as a bronze strip, wear strip, or guide.

For contractors, workshops, and global spare-parts buyers, the 23B7031331, 23B-70-31331 GUIDE KOMATSU is the kind of item that affects operating feel more than it first appears. When guides in the circle support area wear out, the grader can begin to feel loose, rough, noisy, or less precise under blade movement. Replacing the correct guide at the right time helps protect the larger assembly and supports smoother grading performance. Public model references connect this part to several GD555, GD655, and GD675 grader families, depending on serial range and market catalog.

At 3GEN Export, we supply 23B7031331, 23B-70-31331 GUIDE KOMATSU as an OEM supplier for buyers who need reliable export support, careful part matching, and worldwide delivery in 5 working days.

What 23B-70-31331 Actually Does

The short catalog name for this item is simply “GUIDE,” but the surrounding parts-book context gives it more meaning. In 777Parts, the number appears across multiple grader catalog pages tied to circle support mounting parts and circle and blade support adjuster sections. That tells us the part is intended to control wear and guide relative movement in a blade-support or circle-support assembly, not in an engine, axle, or hydraulic pump body.

In practical field terms, a guide like this acts as a sacrificial or semi-sacrificial contact piece. Instead of allowing large structural members to rub directly against each other, the system uses a shaped guide surface to control sliding contact. This helps preserve alignment, reduce friction-related damage, and protect more expensive parent components in the grader frame and blade support assembly. That logic is consistent with the way aftermarket suppliers describe 23B-70-31331 as a wear strip or bronze guide.

This is why the 23B7031331, 23B-70-31331 GUIDE KOMATSU should not be treated as an unimportant small part. In graders, wear interfaces are often what determine whether the whole work equipment assembly feels tight and accurate or loose and tired. A relatively small guide can influence contact quality, support pressure, and the consistency of blade-control response over time.

Why the Shape of This Guide Matters

The uploaded images show a straight, narrow component with a central web and thicker upper and lower flanges. That geometry is useful for a guide because it creates a defined contact profile. The flanged edges help the part sit correctly within its mounting area while the central body carries the working section of the wear surface.

The bronze-like appearance is also important. Bronze and bronze-style wear materials are widely used in applications where low friction, anti-galling behavior, and controlled wear are important. Public supplier listings for 23B-70-31331 repeatedly describe it as a bronze strip or bronze wear guide, which fits the visual evidence in your images.

A part like this is usually expected to do three things well. First, it must fit cleanly into the mounting location. Second, it must maintain dimensional stability while loaded. Third, it must wear in a predictable way instead of damaging the larger housing or support structure around it. That is why guide parts look simple but are actually precision-important components.

Where 23B7031331 Is Used

Public catalog sources connect this part number to a wide spread of Komatsu motor grader applications. The most useful combined picture comes from 3GENEXPORT, regional Komatsu online parts listings, and commercial grader-parts sellers.

3GENEXPORT lists 23B-70-31331 across serial-specific pages for these grader families and variants:

• GD555-3
• GD555-3A
• GD555-3C
• GD555-5
• GD655-3
• GD655-3A
• GD655-3C
• GD655-3C-VH
• GD655-3E0
• GD655-3Y

• GD655-6
• GD675-3
• GD675-3A
• GD675-3E0
• GD675-5
• GD675-6

Komatsu South Africa separately lists the same part under model types including GD675-3, GD675-5, GD675-6, GD675-7, GD555-3, and GD555-5, and marks the part as superseded by 23B-70-31332.

Other aftermarket sellers simplify the fitment to the broader grader families GD555, GD655, and GD675, which matches the overall picture from catalog-based references.

Important fitment note

Because Komatsu grader parts are often serial-number sensitive, the safest buying method is to confirm the machine model and serial range before ordering. The public sources clearly show that 23B-70-31331 appears across multiple GD555/GD655/GD675 variants, but not every grader in those families uses the same page, same revision, or same serial break. Komatsu South Africa also flags this number as superseded, which is another reason to verify before shipment.

Publicly Listed Weight

Public sources do not all show exactly the same weight, but they cluster very closely.

3GENEXPORT lists 0.81 kg for 23B-70-31331.

Komatsu South Africa lists 0.83 kg.

Additional aftermarket listings show 0.84 kg.

For product-page use, the most honest way to present it is:

Estimated weight: approximately 0.81–0.84 kg
Recommended catalog weight reference: 0.83 kg

That wording is accurate, transparent, and more trustworthy than pretending every public source shows the exact same value.

Why Buyers Replace This Part

A guide in the grader circle-support area is usually replaced for one of five reasons.

1. Excessive wear

As the working face thins or the contact profile changes, the system can develop extra clearance. That clearance may lead to rougher blade movement and faster wear in adjacent parts.

2. Uneven contact pattern

If the guide wears unevenly, pressure may stop distributing correctly across the support area. That can increase localized load and shorten the life of nearby components.

3. Surface scoring or galling

A damaged guide surface can turn normal sliding movement into abrasive contact. Once that starts, replacement is usually far cheaper than letting the larger mounting surfaces suffer.

4. Loss of grading precision

Motor graders depend on controlled blade movement. Even small wear parts can affect how stable the blade feels during fine work, slope correction, and finish grading.

5. Preventive service during circle-support rebuilds

Shops often replace guide pieces as part of broader circle-support repairs because reusing worn guides can compromise the value of the rest of the rebuild.

What the Images Suggest About Quality

The uploaded photos show consistent geometry from multiple angles. The edges look straight, the flanges appear balanced, and the working surfaces look intentionally finished rather than roughly cast. That is exactly what professional buyers want from a guide component. It does not need flashy complexity. It needs clean contact faces, stable dimensions, and predictable wear behavior.

The bronze-toned finish also supports the idea that this part is intended for controlled contact rather than heavy structural shock loading. In other words, it is a wear-and-guidance part, not a brute-force support bracket. That distinction helps buyers understand why the correct number matters so much. A mismatched guide may physically resemble the old part, but if the section size or flange profile is wrong, the wear pattern and fit can be wrong too.

How to Check Before Ordering

Before ordering 23B7031331, 23B-70-31331 GUIDE KOMATSU, buyers should confirm a few practical points.

Check the exact number on the old part or parts book

The same grader family may use close-numbered related parts such as 23B-70-31332 or other nearby guide and bracket numbers in the same assembly section. 3GENEXPORT shows 23B-70-31332 as a related guide, and Komatsu South Africa specifically marks 23B-70-31331 as superseded by 23B-70-31332.

Check model and serial range

A GD555, GD655, or GD675 by itself is not always enough. Public catalog references repeatedly separate machines by serial start or market version.

Check quantity per machine

Catalog schemes can show multiple guides in one assembly. For buyers doing a full repair, knowing whether one side or multiple positions need replacement can save downtime and shipping repetition. 3GENEXPORT shows the item as a numbered component on the scheme, which supports that assembly-level ordering approach.
