23S1522390, 23S-15-22390 BUSHING KOMATSU

The 23S1522390, 23S-15-22390 BUSHING KOMATSU is a transmission-side bushing used in Komatsu power train systems. Public parts references place it in the transmission 1st clutch section, while retail listings identify it as a Komatsu bushing sold in the power train or housing-parts category. One public seller also lists the weight as 1.5 KG.

From the uploaded images, this component has the profile of a flanged precision-machined bushing with lubrication holes and a finished internal running surface. Those visible details strongly suggest that 23S-15-22390 BUSHING KOMATSU is designed to stabilize a rotating clutch-related member, maintain correct running clearance, and allow lubricating oil to reach the contact zone during operation. That interpretation also fits the public catalog placement in the 1st clutch assembly.

At 3GEN Export, we supply 23S-15-22390 BUSHING KOMATSU as an OEM supplier for global buyers who need dependable heavy machinery spare parts with worldwide delivery in 5 working days.

Product Overview

Public listings describe 23S-15-22390 BUSHING KOMATSU simply as a bushing, but its application context is much more specific than that basic name suggests. The part is associated with transmission clutch internals rather than a general-purpose sleeve or external frame bushing. A public Komatsu parts reference places it directly in the transmission 1st clutch section, which makes it a functional internal support component rather than a cosmetic or secondary item.

In practical workshop terms, 23S-15-22390 BUSHING KOMATSU helps a moving transmission member rotate in a controlled manner inside the clutch assembly. A correctly fitted bushing keeps the mating surface supported, protects alignment, and helps the oil film do its job. When buyers look for this number, they are usually dealing with a real transmission repair, an overhaul, or a clutch-section inspection where correct part-number matching matters more than visual similarity alone.

The alternate format 23S1522390 is also used publicly in the market, so both search styles are valid for procurement teams, workshops, and dealers. Public product pages show 23S-15-22390 as the main SKU and 23S1522390 as an alternate number.

What the Design Tells Us

Flanged outer construction

The flanged shoulder is one of the most important visible features of 23S-15-22390 BUSHING KOMATSU. That shoulder provides positive seating in the housing and helps control axial positioning once the part is installed. In clutch assemblies, stable axial location matters because even small movement can affect internal alignment and long-term wear patterns. The design seen in the images is consistent with a bushing that must sit accurately in a machined transmission bore.

Precision-finished inner bore

The smooth inner running surface visible on 23S-15-22390 BUSHING KOMATSU indicates that it is meant for controlled rotational contact rather than rough static support. That kind of finish is important in lubricated transmission sections because the quality of the contact surface directly affects friction, oil retention, and wear behavior. A part placed in the 1st clutch area must support repeatable mechanical motion, and the inner finish shown in the images fits that requirement.

Lubrication holes

Another valuable clue is the presence of oil-feed holes. These openings are not decorative details. They are typically used to direct oil toward the running surface or maintain lubrication flow during operation. That feature supports the conclusion that 23S-15-22390 BUSHING KOMATSU works in a lubricated clutch or transmission environment where heat control and oil-film stability are essential.

Why This Part Matters in the 1st Clutch Section

A bushing in the 1st clutch section has a more serious job than many buyers assume. The first clutch group is part of the power train, where torque transfer, controlled engagement, and internal rotational stability all matter. When 23S-15-22390 BUSHING KOMATSU is in good condition, it helps the surrounding clutch parts run with proper support and predictable clearance. When it is worn, scoring, looseness, heat buildup, and secondary wear can spread to the adjoining components.

This is why experienced maintenance teams often replace a part like 23S-15-22390 BUSHING KOMATSU during deeper clutch or transmission service rather than waiting for a complete failure. A worn internal support part can damage more expensive components over time, especially in machines that work under long duty cycles, frequent shifting, or heavy operating loads.

Compatible Komatsu Models

Public compatibility references connect 23S-15-22390 BUSHING KOMATSU with Komatsu grader transmission applications in the same 1st clutch family. Public catalog results and related transmission references commonly associate it with the following grader lines: GD605A, GD611A, GD621A, GD621R, GD623A, GD625A, GD661A, and GD663A. Available snippets also show serial-based references such as GD625A-1 S/N 60001-UP for North America and GD661A-1 S/N 10001-UP.

For your product page, the safest compatibility wording is:

GD605A series

GD611A series

GD621A series

GD621R series

GD623A series

GD625A series

GD661A series

GD663A series

Because public snippets do not show every serial line in one place, it is still best to confirm by machine serial number and parts book before final purchase. That is especially important in power train repairs, where nearby numbers can look similar but differ in bore, width, oil passage layout, or assembly position.

Technical Details and Commercial Listing Data

Publicly accessible seller information identifies 23S-15-22390 BUSHING KOMATSU as a Komatsu bushing in the power train or housing parts area. The clearest commercial details visible online are the OEM number, alternate number, category placement, and weight. One seller lists it under Power Train and Housing Parts, while another shows the alternate product number 23S1522390.

For a clean website spec block, you can use the following structure:

Part Number: 23S-15-22390

Alternative Part Number: 23S1522390

Product Name: Bushing

Brand: Komatsu-compatible replacement part

Application Area: Transmission / 1st Clutch

Category: Power Train / Housing Parts

Weight: 1.50 KG

Inspection and Installation Notes

Before fitting 23S-15-22390 BUSHING KOMATSU, the housing bore should be checked for scoring, distortion, contamination, and seat damage. A new bushing cannot deliver proper service life if the surrounding housing or mating part is already worn beyond tolerance. This is particularly important in a clutch section, where the running alignment depends on more than just the replacement part itself.

During assembly, oil passages must also be kept clean and aligned correctly. Since the part visibly includes lubrication holes, installers should make sure the oil route is not blocked during fitting. A correctly seated and properly lubricated 23S-15-22390 BUSHING KOMATSU will help the clutch section run more smoothly and reduce the chance of premature wear on the neighboring parts.
