23A7015210, 23A-70-15210 HOUSING KOMATSU

If you are sourcing a replacement for 23A7015210, 23A-70-15210 HOUSING KOMATSU, this part is best understood as a machined grader housing used in the circle reverse gear section of Komatsu motor graders. Komatsu’s own online parts store lists 23A-70-15210 as a HOUSING under Work Equipment Others, and multiple catalog references place it inside the CIRCLE REVERSE GEAR (1/2) group on several grader platforms.

From the product images, this component has a square mounting flange, a precision-machined central bore, four larger corner fixing holes, and smaller threaded holes around the inner opening. That geometry strongly suggests a support and locating housing that helps hold internal reverse-gear-related elements in position while maintaining alignment through the bore. The catalog context supports that interpretation, because the same assembly references nearby parts such as bushings, plate, shaft, worm gear, O-rings, oil seal, plug, and shim assembly, which are exactly the kinds of companion components normally associated with a supported rotating or driven gear arrangement.

For buyers, workshop managers, and parts teams, that matters because a housing in this location is not just a passive metal block. It helps maintain mechanical alignment, fastening stability, sealing integrity, and repeatable fit inside the grader’s circle reverse gear section. When the bore wears, the mounting face distorts, or the fastener seats lose precision, the downstream effect can show up as poor gear alignment, uneven load distribution, accelerated bushing wear, or oil-seal issues. That is why 23A7015210, 23A-70-15210 HOUSING KOMATSU should be treated as a fit-critical grader part rather than a generic housing. The placement of the part in Komatsu grader reverse-gear diagrams across multiple model families supports that role.

Product Overview

23A7015210, 23A-70-15210 HOUSING KOMATSU is a Komatsu grader housing identified by both the spaced format 23A-70-15210 and the continuous format 23A7015210. Both forms appear in online parts references, and both should be used in SEO and search indexing because industrial buyers often search either the hyphenated or unhyphenated version. Official and catalog sources consistently identify the part name simply as HOUSING.

The part belongs to the grader work-equipment side of the machine rather than engine, cab, or simple consumable systems. Komatsu’s official store classifies it under Work Equipment Others, while catalog pages connect it to the circle reverse gear group used on multiple Komatsu graders. In other words, this is not a cosmetic cover or low-importance bracket. It belongs to a functional motion-transfer area tied to blade and circle operation, where positioning accuracy and bore condition matter.

From an e-commerce perspective, that makes 23A7015210, 23A-70-15210 HOUSING KOMATSU a highly specific service part for grader owners who need reliable replacement fit. The strongest buyer intent around this product usually comes from fleet maintenance teams, rebuild shops, overseas dealers, contractors, and road-equipment specialists searching by exact part number. Because the term “housing” is broad on its own, the SEO strength of this page comes from combining the exact Komatsu code with the application context: grader, circle reverse gear, and the relevant model families. The search evidence shows that this part repeatedly appears in that exact grader context.

What 23A7015210, 23A-70-15210 HOUSING KOMATSU Does

Based on catalog placement and the visible machining in the images, 23A7015210, 23A-70-15210 HOUSING KOMATSU functions as a structural support housing within the circle reverse gear arrangement of Komatsu motor graders. The central bore provides the controlled internal surface where associated parts can seat or rotate, while the flange and bolt pattern provide secure positioning against the mating structure. The presence of related bushings, oil seal, O-ring, plate, worm gear, and shims in the same assembly strongly indicates that the housing participates in locating and stabilizing internal moving parts rather than acting as a simple spacer. That is an engineering inference, but it is grounded in the catalog grouping and neighboring component list.

In grader operation, the circle reverse gear section is central to controlled movement and positioning of the blade circle. A housing in this zone needs to keep mating parts square, maintain bore accuracy, and hold sealing elements correctly. If the bore is worn or the flange face is no longer true, even a good shaft or bushing can underperform. That is one reason maintenance buyers often replace the housing when rebuilding the surrounding reverse-gear set instead of replacing only the smaller wear items. The multi-model catalog usage of 23A7015210, 23A-70-15210 HOUSING KOMATSU suggests that Komatsu used this design across a broad grader range, reinforcing its importance as a proven structural part within that assembly family.

Visual Design and Build Characteristics

The uploaded images show a compact but heavy-duty housing with a robust square flange and a deep cylindrical body. The machining marks are visible around the bore and flange surfaces, which is exactly what buyers expect on a component where fit and face accuracy matter. The large corner holes appear intended for the main mounting fasteners, while the smaller threaded holes near the bore likely accommodate additional fastening or retention hardware inside the assembly. Because the edges, bore, and shoulder transitions are cleanly machined, the part presents as a precision support component rather than a rough structural casting.

Another important visual feature is the stepped cylindrical section behind the flange. That stepped shape usually helps with locating the part inside a mating opening or against another seated surface. It also suggests that 23A7015210, 23A-70-15210 HOUSING KOMATSU was designed for controlled assembly stack-up, not loose-tolerance placement. On grader assemblies where loads, vibration, and repetitive movement are constant, that kind of stepped geometry helps preserve positioning under working conditions.

The inner bore also appears thick-walled and uniform, which is important for load stability and long-term service life. For workshops, this matters because housings in reverse-gear areas often face repetitive stress, contamination risk, and alignment-sensitive operation. A well-machined bore and proper flange flatness are therefore major buying points when sourcing a replacement.

The sources above clearly show serial breaks on several applications, so that check is not optional.

Why This Housing Matters in Real-World Maintenance

For a machine owner, a worn or damaged housing can create bigger problems than many people expect. In a reverse-gear-related assembly, the housing controls the environment in which the surrounding parts operate. If that environment is no longer dimensionally stable, the load path changes. Bushings may wear faster, seals may not seat correctly, shims may no longer compensate as intended, and the gear train may develop play or irregular contact patterns. The fact that the catalogs place this housing next to bushings, seals, worm gear, shaft, and shim assemblies supports that maintenance logic.

That is why buyers looking for 23A7015210, 23A-70-15210 HOUSING KOMATSU are usually not shopping for a generic metal part. They are solving a specific grader repair problem where correct bore geometry, mounting alignment, and assembly fit are critical. A precisely supplied replacement helps restore confidence during rebuilds and reduces the risk of repeating labor because of mismatch or poor seating.

Buying Guidance for Workshops and Dealers

When ordering 23A7015210, 23A-70-15210 HOUSING KOMATSU, the first checkpoint should be the machine model and serial number. The online parts evidence shows the same housing code across several Komatsu grader families, but it also shows serial-range splits inside those families. That means the part may be correct for one GD-series machine and not for another if the serial break is ignored.

The second checkpoint should be the mating assembly. Since catalog references place this housing with bushings, seal elements, shims, and reverse-gear components, it is smart to inspect those related parts at the same time. If the old housing has worn unevenly, there is a good chance at least one neighboring component has also experienced abnormal wear. The parts-book snippets support that relationship.

The third checkpoint is shipping and stock planning. With a cited catalog weight of 4.45 kg, this is not an oversized freight item, but it is heavy enough to justify careful packaging and correct logistics quoting. That makes it a practical part for international dispatch when packed correctly.
