2386312340, 238-63-12340 CYLINDER KOMATSU

The 2386312340, 238-63-12340 CYLINDER KOMATSU is a Komatsu grader hydraulic component publicly listed in the hydraulic-system category, and the strongest open sources connect this exact number to blade-lift-cylinder applications on several GD-series graders. Public listings identify the part simply as CYLINDER, while 3GEN Export’s product page lists the exact reference as a Komatsu hydraulic cylinder with an approximate weight of 12 kg.

That matters because this part is not best understood as a complete left-hand or right-hand cylinder assembly. Public parts-catalog and repair-kit references show that 238-63-12340 appears as the cylinder body inside a larger blade lift cylinder group, working together with nearby components such as 238-63-12320 ROD, PISTON and 707-29-80940 HEAD, CYLINDER. In practical terms, that means the 2386312340, 238-63-12340 CYLINDER KOMATSU is best described as the main hydraulic barrel or cylinder section used within a Komatsu grader blade-lift assembly.

From the uploaded images, that interpretation fits very well. The part has the long straight tubular form expected from a pressure-bearing hydraulic body, along with side connection points near the center and compact end fittings that suit a working hydraulic circuit. It does not look like a piston rod, gland, seal kit, or full steering ram. It looks like the main cylinder body that holds hydraulic pressure and supports controlled linear blade-lift motion in grader service. This visual reading is an inference from the images, but it is strongly supported by the public blade-lift references tied to this exact number.

What the 2386312340, 238-63-12340 CYLINDER KOMATSU does

The job of the 2386312340, 238-63-12340 CYLINDER KOMATSU is to form the pressure chamber of the blade-lift cylinder system on Komatsu graders. In a hydraulic lift circuit, the cylinder body is where fluid pressure is contained and converted into usable linear force through the piston and rod assembly. Because this exact number is publicly shown inside blade-lift-cylinder groups rather than sold only as a generic hydraulic tube, its role is much more specific: it is a functional grader work-equipment part tied directly to moldboard lift performance.

On a grader, blade lift is one of the most important working motions. The operator constantly adjusts blade height to shape roads, maintain crown, trim shoulders, spread aggregate, and correct uneven surfaces. When the cylinder body in that system is dimensionally correct and hydraulically sound, the blade can rise, lower, and hold position with better consistency. When the barrel is worn, scored, corroded, or distorted, the whole lift assembly can suffer from leakage, unstable movement, or short seal life. That is why the 2386312340, 238-63-12340 CYLINDER KOMATSU has real operational value even though it may look like a simple tube from a distance. Its accuracy supports the function of the complete lift assembly around it.

This is also why workshops search for the exact number instead of buying a loose generic cylinder body. Public catalog references connect this exact Komatsu number to known grader platforms and to specific blade-lift-cylinder groups. For maintenance teams, that gives confidence that the part belongs in a real Komatsu hydraulic structure rather than being an approximate aftermarket match without documented context.

Why this cylinder matters in real grader work

A motor grader earns its value through precision. The machine is expected to keep the blade under steady control while working over long distances, changing materials, and uneven surfaces. Lift quality affects whether the operator can maintain a fine surface finish or ends up making repeated corrections. Since public sources place 238-63-12340 directly inside blade-lift-cylinder groups, this part should be viewed as a critical hydraulic structure in the machine’s grading accuracy, not just a replaceable shell.

In road maintenance and construction work, blade-lift stability affects productivity every hour the grader is on the ground. A poor cylinder body can create internal leakage, seal damage, or inconsistent lift response, all of which make it harder to hold precise blade position. In mining roads, municipal maintenance, and infrastructure jobs, that can translate into slower work and more rework. For that reason, the 2386312340, 238-63-12340 CYLINDER KOMATSU is commercially important to operators, workshops, and fleet managers alike. It supports not only hydraulic integrity but also the final quality of the grader’s work.

Another important point is that this kind of purchase usually happens during real repair work. Buyers generally do not search a part number like 2386312340 casually. They search it when a blade-lift cylinder has been opened and the body itself is found to be worn or damaged beyond a simple seal change. Public repair-kit references reinforce that exact context by showing the cylinder body as one piece of a larger lift-cylinder repair structure.

Visual review of the uploaded part

The uploaded images show a long cylindrical body with a smooth industrial finish and a central enlarged section where the side ports are located. That layout is exactly what many buyers expect from a hydraulic cylinder barrel designed to feed fluid into a working chamber while keeping the main body strong and straight under pressure. The 2386312340, 238-63-12340 CYLINDER KOMATSU does not present as a decorative or non-structural part. It looks like a true hydraulic body made for heavy grader use.

The side connection points are especially useful visual clues. They show that fluid routing is part of the design rather than an afterthought. On a grader lift circuit, port placement and body geometry matter because the assembly must withstand pressure and repeated movement without compromising sealing performance. The smooth exterior finish and compact end plates suggest a finished hydraulic component prepared for machine integration, which aligns well with the public hydraulic-system classification and blade-lift application references.

The part also looks proportionally correct for grader-duty work. It is longer and more substantial than many small auxiliary cylinders, yet its layout is still clean and practical. That visual balance fits a blade-lift application, where controlled vertical motion and repeated hydraulic cycling are central to the machine’s work. Again, this is an image-based inference, but it is consistent with the documented parts-group placement.

Publicly linked KOMATSU models

The strongest public fitment source I found links the 2386312340, 238-63-12340 CYLINDER KOMATSU to the following Komatsu grader families:

Komatsu GD505A
Komatsu GD521A
Komatsu GD525A
Komatsu GD605A
Komatsu GD611A
Komatsu GD621A
Komatsu GD621R
Komatsu GD623A
Komatsu GD625A
Komatsu GD661A

That broader fitment list is supported by more model-specific public references. A GD623A-1 parts page shows 238-63-12340 in the BLADE LIFT CYLINDER group, and public seller-style grader parts listings also show the same number under GD661-related parts. UrParts additionally lists the same number on GD611 and GD661 grader catalog pages. Taken together, those references make the GD-series blade-lift context much more convincing than a single isolated seller claim.

At the same time, final fitment should still be checked by model and serial number before sale. Komatsu graders often have serial-range breaks and assembly revisions, especially in hydraulic equipment. The public sources are strong enough to support the main GD-series compatibility picture, but serial confirmation remains the safest last step for accurate supply.

Technical details and specifications

The clearest public naming for this part is simply CYLINDER. That naming may sound generic, but the surrounding public references make its position much more precise: it is the cylinder body associated with a blade-lift-cylinder group on Komatsu graders, rather than a fully assembled cylinder unit or unrelated hydraulic component.

This reference is commonly searched in both formats:

2386312340
238-63-12340

The strongest exact public weight figure is approximately 12 kg, taken from 3GEN Export’s product page for the exact item. Other open sources I found confirmed the part category and machine context, but did not provide a more authoritative exact weight figure for the same number. For product-page use, 12 kg is the most defensible public figure available.

Public seller information for the exact listing describes the part as made from high-strength steel with an anti-corrosion finish and designed for hydraulic precision movement. Because that material statement comes from a seller page rather than a factory metallurgy document, it is best treated as seller-provided product information, not as an official Komatsu materials sheet. Still, it matches what the images show: a finished hydraulic body intended for demanding work conditions.

The strongest functional description remains this: the 2386312340, 238-63-12340 CYLINDER KOMATSU is the cylinder body used within a Komatsu grader blade-lift-cylinder assembly. That interpretation is directly supported by parts-group references showing the cylinder body, head, and piston rod listed together under blade-lift-cylinder breakdowns.

Why buyers search both number formats

Industrial buyers search parts in several ways. A procurement officer may use 2386312340 from inventory software, a printed quote, or an ERP record. A technician may use 238-63-12340 from a workshop manual or parts breakdown. A hydraulic-repair specialist may not know the number first and instead search broader phrases like Komatsu blade-lift cylinder body, Komatsu grader hydraulic cylinder, or GD623A blade-lift cylinder part. Public search results already show these patterns, with the same number appearing in seller listings, model-specific parts pages, and repair-kit contexts.

That is why the best SEO structure for this listing is not to repeat the full exact phrase mechanically in every paragraph. A better page keeps both number formats visible in the title, technical section, fitment section, and summary, while using natural support terms like Komatsu blade-lift cylinder body, grader hydraulic barrel, hydraulic lift component, and moldboard lift cylinder part in the main body. That gives better reach for Google and AI-driven search without creating unnatural density.

Why this part is commercially valuable

The 2386312340, 238-63-12340 CYLINDER KOMATSU is commercially important because it solves a real rebuild problem. When a blade-lift assembly is dismantled and the cylinder body is damaged, a seal kit alone is not enough. The workshop needs the correct cylinder structure so the piston, seals, and head can work in the right geometry again. Public repair-kit references make that point clearly by showing the cylinder body as one defined element within the lift-cylinder system, not as an interchangeable generic tube.

For fleet owners, that means a worn barrel can hold back the whole machine from returning to productive work. For repair shops, it means the difference between a proper hydraulic rebuild and a short-lived repair. For parts sellers, it means the item has clear B2B demand because it is tied to exact Komatsu part numbering, real GD-series grader fitment, and functional blade-lift applications.
