23A4611370, 23A-46-11370 PIN KOMATSU

Rear frame pin for Komatsu motor grader articulation and frame linkage systems

The 23A4611370, 23A-46-11370 PIN KOMATSU is a Komatsu motor grader spare part publicly identified as PIN and linked to the rear frame section in multiple catalog-style sources. The clearest model-specific evidence places it on GD525A-1 S/N 60001-UP, where it is listed as a rear frame pin, and broader cross-reference sources associate the same part number with grader families including GD511A-1, GD521A-1, GD525A-1, GD525A-1C, GD611A-1, GD621A-1, GD623A-1, GD625A-1, GD625A-1C, and GD725A-1.

From the images, this part appears to be a heavy-duty machined pin with a threaded end, a reinforced spherical center section, and a welded tab or stop plate on the head. That geometry is consistent with a structural pivot or linkage pin used in a grader frame connection rather than a small fastener. The shape-based description comes from your images, while the rear frame application comes from public parts references.

What is 23A4611370, 23A-46-11370 PIN KOMATSU?

Public sources identify 23A-46-11370 simply as PIN, but the machine section provides the real functional context. An 3GEN page for GD525A-1 S/N 60001-UP places this number under FRAME AND GUARD – REAR FRAME, and the broader rear frame parts page shows it as item 9, with quantity 2, for serial range 60001–60018.

A broader 3GEN cross-reference page also lists 23A-46-11370 PIN Komatsu and connects it to model families such as GD521A-1, GD523A-1, and other graders in similar rear frame contexts. A commercial supplier page likewise markets it as PIN – REAR FRAME and lists a wider group of Komatsu grader models. Taken together, the strongest supported description is that this part is a Komatsu motor grader rear frame pin.

For your website, the safest core product identity is:

Core product identity

• Part number: 23A4611370 / 23A-46-11370
• Product name: PIN
• Application area: rear frame
• Machine type: Komatsu motor grader

Why this rear frame pin matters

A rear frame pin is not a cosmetic part. In motor graders, the rear frame area carries structural load, articulation-related movement, and repeated shock from grading work, uneven surfaces, and steering dynamics. Because public sources place 23A-46-11370 directly in the rear frame section, it is appropriate to describe it as a structural connection pin used in a major frame linkage point.

In practical service terms, a part like this matters because wear in a frame pin can affect fit, movement accuracy, and the service life of surrounding bushings, brackets, and frame contact points. That is a mechanical inference based on the documented rear frame placement and the heavy-duty design visible in the images, not a quoted factory failure note. The visible threaded end and robust body further support the idea that this is designed for secure installation and controlled pivot support in a high-load area.

Visual characteristics from the images

From the images you provided, the part shows:

• a precision-machined cylindrical body
• a threaded mounting end
• a broad spherical or barrel-shaped center section
• a welded stop or lock tab on the head
• a small cross-hole / lubrication or retaining feature in the body

These points are image-based observations rather than catalog specs.

Weight in KG

I could not verify a reliable public KG weight for 23A4611370, 23A-46-11370 PIN KOMATSU from trustworthy accessible sources. The public pages I found confirm the part name, section, and compatible models, but they do not provide a dependable weight value for this exact number. Because of that, the safest product-page wording is:

Weight: please confirm before shipment.

Compatible KOMATSU models

The strongest publicly supported model references for 23A-46-11370 include:

• GD525A-1 , directly supported by a model-specific rear frame page for S/N 60001-UP, with the pin shown for 60001–60018.
• GD511A-1
• GD521A-1
• GD525A-1C
• GD611A-1
• GD621A-1
• GD623A-1
• GD625A-1
• GD625A-1C
• GD725A-1 , these appear on a commercial supplier fitment list for the same part number.

A 3GEN cross-reference page also associates the number with additional grader families in rear frame applications, including GD523A-1. That supports broader grader relevance, but the most confident list remains the models explicitly surfaced in the search results above.

Important fitment note

Final compatibility should always be confirmed by:

• exact part number
• machine model
• serial number
• rear frame parts diagram

That is especially important for structural frame pins, because similar-looking pins may differ in diameter, shoulder design, retention method, or serial-range usage. The strongest serial-specific evidence I found is GD525A-1 S/N 60001-UP, with this pin specifically shown for S/N 60001–60018 on one page.

Product function and working characteristics

The 23A4611370, 23A-46-11370 PIN KOMATSU is best described as a rear frame connection pin for Komatsu grader applications. Public sources support the rear frame location, and the heavy-duty construction visible in the images supports describing it as a load-bearing pivot or structural connection pin.

For workshops and fleet owners, this kind of part is relevant during:

• rear frame repair
• articulation-area service
• pin and bushing replacement work
• grader rebuild projects
• structural restoration after wear inspection

Those uses are grounded in the published rear frame placement and the component form shown in the images.

Key benefits of 23A4611370, 23A-46-11370 PIN KOMATSU

Supports rear frame linkage integrity

Public parts sources place this part directly in the rear frame section, so it should be positioned as a working frame-connection component rather than a generic metal pin.

Useful across multiple grader models

The public model references span several Komatsu grader families, which increases its value for professional workshops and resellers handling grader repairs.

Strong exact-number search value

Using both 23A4611370 and 23A-46-11370 helps the page match how buyers search from parts manuals, service records, and stock lists.

Good fit for pin-and-bushing service work

A public commercial category page groups 23A-46-11370 & 23A-46-11371 PIN KOMATSU GRADER under pin-and-bushing products, which supports its relevance in grader joint and frame maintenance workflows.

Common reasons for replacement

The public sources do not list explicit failure modes, so the following are practical mechanical inferences:

• wear from repeated pivot movement
• surface damage at the contact area
• looseness in the rear frame connection
• damage found during bushing replacement
• replacement during major frame rebuild work

These are reasonable because the part is documented as a rear frame pin and clearly belongs to a pin-and-bushing style service environment.
