23B7351190, 23B-735-1190 GUIDE KOMATSU

Reliable grader circle support guide for Komatsu machines

The 23B7351190, 23B-735-1190 GUIDE KOMATSU is a grader wear and guidance component used in Komatsu circle support and power tilt related assemblies. Public parts references identify this exact part number as GUIDE and connect it to several grader platforms, including GD525A-1, GD511A-1, GD661A-1, and additional GD-series machines in circle support or power tilt blade support sections.

For buyers searching online, it is important to use both number styles naturally on the page: 23B7351190 and 23B-735-1190. Many workshops, resellers, and procurement systems search by the compact number, while catalog pages and search engines often index the hyphenated format. A strong listing should therefore include the full keyword phrase 23B7351190, 23B-735-1190 GUIDE KOMATSU in a natural way throughout the content. At 3GEN Export, we supply this part as an OEM supplier and support worldwide delivery in 5 working days for urgent grader spare parts needs.

What is 23B7351190, 23B-735-1190 GUIDE KOMATSU?

The 23B7351190, 23B-735-1190 GUIDE KOMATSU is publicly cataloged as a Guide. Multiple sources place it in assemblies such as CIRCLE SUPPORT, BLADE AND CIRCLE SUPPORT (FOR POWER TILT), SUPPORT (FOR POWER TILT BLADE), and WORK EQUIPMENT CONTROL, POWER TILT CYLINDER MOUNTINGdepending on machine series. That tells us this is not a decorative or secondary piece. It is a function-specific component used where stable positioning, guided contact, and controlled movement are important in grader work equipment systems.

Based on the product images, the part has a long channel-style fabricated profile with a mounting ear at one end. Its geometry strongly suggests a guide or wear-contact role rather than a rotating, sealing, or hydraulic-pressure role. This interpretation aligns with the public parts references identifying it as a Guide in circle support and power tilt related assemblies. This interpretation is based on the visible design and published assembly locations.

The strongest fitment evidence comes from the model lists shown on public parts pages, but because grader configurations can vary by serial range, regional version, and work equipment option, the safest practice is still to confirm the machine model and serial number before ordering. That is especially important for power tilt and circle support assemblies.

Assembly position and working role

One of the most useful details publicly available is where this guide sits in the machine structure. Sources place it in circle support, blade and circle support, and power tilt related mounting sections. In practical terms, that means the 23B7351190, 23B-735-1190 GUIDE KOMATSU supports controlled alignment and movement in a working area that directly affects grader blade positioning and equipment stability.

Graders depend on precise movement more than many other types of heavy equipment. If a guide in the support area is worn, loose, or deformed, the operator can experience reduced motion accuracy, uneven contact, vibration, or accelerated wear in related support components. These are reasonable engineering conclusions based on the part’s published location in circle support and power tilt assemblies.

Visual Inspection

are very useful because they show a part that visually matches the published function.

Long channel construction

The body has a long, straight, channel-like profile. This shape is commonly used where one part must guide or stabilize another over a defined contact length.

Positive mounting point

The end tab with a mounting hole indicates fixed installation into a support structure. This supports the idea that the part acts as a stable guide rather than a free-moving item.

Wear-guidance geometry

The flat parallel faces suggest controlled contact surfaces. In a grader support system, this kind of form helps maintain alignment while distributing contact over a usable length.

Heavy machinery finish

The industrial coating and fabricated steel appearance are appropriate for a grader work-equipment component exposed to dirt, vibration, and outdoor conditions.

These observations are image-based, but they align closely with the published description of the part as a Guide in Komatsu grader support systems.

Why this guide matters in real operation

The 23B7351190, 23B-735-1190 GUIDE KOMATSU may look simple, but components like this are important because graders rely on controlled geometry. Blade performance is not just about hydraulic force. It is also about how accurately the blade and circle support system can hold alignment while rotating, tilting, and working under load.

A worn guide can contribute to:

Reduced accuracy

If guidance surfaces degrade, fine grading precision may drop.

Higher related wear

Misalignment usually increases stress on nearby supports, collars, bolts, shims, and mating parts.

More vibration and looseness

Poor support contact can allow extra movement in assemblies that should stay controlled.

Maintenance inefficiency

Replacing a worn guide during scheduled service can help avoid larger repairs later.

These are functional inferences based on the guide’s assembly role, not direct quotations from a service manual. They are consistent with how support guides typically behave in heavy equipment work systems.

Product Description

The 23B7351190, 23B-735-1190 GUIDE KOMATSU is a grader support guide designed for selected Komatsu GD-series applications. Public references place this exact part number in the circle support, blade and circle support, and power tilt blade support related sections of several Komatsu graders, confirming its function as a guidance and support component within the work equipment assembly.

a long fabricated channel body with a formed end bracket and mounting hole, making it suitable for controlled contact and positional guidance inside the related support structure. Its shape indicates a part designed to help maintain equipment alignment, reduce irregular movement, and support consistent grader performance in demanding field conditions.
