23B7016160, 23B-70-16160 WORM KOMATSU

Heavy-Duty Circle Reverse Worm Gear for Komatsu Motor Graders

The 23B7016160, 23B-70-16160 WORM KOMATSU is a grader transmission and circle-drive component used in the circle reverse gear section of Komatsu motor graders. In public Komatsu-style parts references, this part is identified as GEAR, WORM, and one catalog diagram places it directly inside the CIRCLE REVERSE GEAR (2/2) assembly for the GD625A-1 S/N 50001-UP grader.

That placement matters because this is not a random rotating part or a simple shaft. A worm gear in the circle reverse system has a direct effect on how the grader’s circle mechanism transmits motion and supports controlled blade positioning. In real working conditions, that means the 23B7016160, 23B-70-16160 WORM KOMATSU is tied to precision, stability, and consistent grader response during road shaping, shoulder correction, ditch work, and fine finishing passes. This functional interpretation is based on the part’s documented location in the circle reverse gear assembly.

We deliver all over the world in 5 working days, helping workshops, fleet owners, dealers, and contractors reduce downtime when grader transmission and drive parts need urgent replacement.

What Is 23B7016160, 23B-70-16160 WORM KOMATSU?

The clearest public identification available for this part is GEAR, WORM. A Komatsu-style diagram for the GD625A-1 lists 23B-70-16160 GEAR, WORM as item 1 in the circle reverse gear assembly. That tells us two important things. First, the part is a worm gear rather than a plain shaft or housing component. Second, it belongs specifically to the circle reverse gear system on a Komatsu grader.

An additional grader parts listing groups 23B-70-15150, 23B-70-15151, and 23B-70-16160 together under CIRCLE DRAWBAR SUPPORT AND CIRCLE REVERSE, reinforcing that this part belongs to the grader circle-drive area rather than to engine, axle, or hydraulic-cylinder sections.

From a buying perspective, this is important because graders rely on controlled blade-circle movement to do precise work. A worm gear in this assembly is one of the key mechanical elements that helps transmit rotational force in a compact and accurate way. When buyers search for 23B7016160 or 23B-70-16160, they are usually looking for an exact-fit grader worm gear that restores normal circle reverse function.

Why This Worm Gear Matters on a Komatsu Grader

Motor graders are built for precision. Unlike many machines that mainly focus on bulk material movement, a grader must shape surfaces cleanly and repeatedly over long distances. That kind of work depends on accurate blade-circle control, and the circle reverse gear assembly plays a major part in that system. Since this part is documented inside that assembly, the 23B7016160, 23B-70-16160 WORM KOMATSU should be understood as a working control component, not a minor accessory.

In practical terms, a healthy worm gear helps the grader maintain smoother mechanical engagement inside the circle reverse mechanism. That can contribute to steadier blade-circle response, more predictable movement, and better operating confidence for the grader operator. This is a grounded operational inference based on the part’s documented role in the circle reverse gear system.

When a worm gear in this area becomes worn, scored, damaged, or improperly matched, the machine may lose some of the mechanical consistency that makes fine grading possible. That can show up as rougher movement, less precise control, or increased wear on connected parts. For contractors and service teams, that is why an exact replacement matters.

Part number formats

This part is commonly searched and listed in both of these formats:

23B7016160

23B-70-16160

Official part identification

Public Komatsu-style catalog data identifies the part as:

GEAR, WORM

Product section

The part belongs to the grader’s:

Circle reverse gear
Circle drawbar support and circle reverse category

Weight in KG

The strongest practical weight figure I found is 6 kg from a commercial product listing. I did not find a clearer catalog-based weight number in the accessible sources, so 6 kg is the best available listing weight I can support here.

Material and construction

A 3GEN Export product page describes the part as being made from high-grade alloy steel with a corrosion-resistant coating. That is seller-provided specification language rather than factory catalog data, so it is best treated as commercial product-detail information, not a Komatsu-issued engineering sheet.

Primary mechanical role

A product listing describes the part’s function in terms of smooth torque transmission and grader control, while the Komatsu-style diagram places it in the circle reverse assembly. Together, these sources support describing the part as a worm gear used to transmit controlled motion in the grader circle-drive system.

Compatible KOMATSU Models for 23B7016160, 23B-70-16160 WORM KOMATSU

The most precise model evidence I found from a parts-book style source is for Komatsu GD625A-1 S/N 50001-UP, where 23B-70-16160 appears directly in the circle reverse gear diagram. That is the strongest fitment reference available in the sources I reviewed.

A commercial 3GEN Export listing also presents the part as compatible with several Komatsu grader models:

GD511
GD555
GD655
GD675

Because those model references come from a commercial listing rather than a factory diagram, the safest way to present compatibility is this:

Supported and market-referenced applications

Confirmed by diagram: GD625A-1 S/N 50001-UP

Commercially referenced grader models: GD511
GD555
GD655
GD675

Important fitment note

Final compatibility should always be confirmed by exact part number, machine model, and serial number before ordering. The GD625A-1 fitment is directly supported by a parts-book style diagram, while the GD511, GD555, GD655, and GD675 references come from a seller listing and should be treated as market fitment guidance.

Product Design and Working Characteristics

The images show a compact, heavy-duty worm gear with machined journals at both ends and a central helical worm section. That visual profile matches the kind of part used in a circle reverse gear mechanism, where controlled meshing and dependable rotation are required.

This kind of design is especially valuable in grader service because worm gears are commonly used where compact force transfer and controlled engagement matter more than raw speed. In a grader circle mechanism, that supports the kind of measured movement needed for accurate blade-circle control. This explanation is a mechanical inference grounded in the part’s documented identification as a worm gear in the circle reverse gear assembly.

A seller listing also emphasizes smooth torque transmission, durability, and resistance to harsh operating environments. That language is commercial in nature, but it does align with what buyers expect from a grader worm gear used in road maintenance and construction conditions.

Benefits of 23B7016160, 23B-70-16160 WORM KOMATSU

Supports precise grader control

Because the part is used in the circle reverse gear assembly, it contributes to controlled motion within one of the grader’s most important work systems. That helps support precision during surface shaping and finishing work.

Built for grader-specific service

This is not a generic industrial worm. Public sources place it specifically in Komatsu grader circle reverse applications, which gives buyers more confidence when they need an application-specific replacement.

Useful for full transmission-area repair work

When a circle reverse assembly is being repaired or rebuilt, a worm gear like this is one of the core components that may require inspection or replacement. The fact that it appears as a named item in the assembly diagram reinforces its importance in that system.

Good search visibility under multiple formats

Buyers search using both 23B7016160 and 23B-70-16160, and product pages that include both naturally are more likely to capture real parts-search behavior. This conclusion is based on the way public listings present both number formats.

Typical Reasons Buyers Replace This Part

Most customers do not look for this worm gear unless there is a real grader service need. Common scenarios include circle reverse gear wear, damaged tooth surfaces, rough mechanical engagement, or complete grader transmission-area overhaul.

Another common reason is fleet refurbishment. When graders are rebuilt for resale, export, or extended service life, circle reverse components are often inspected closely because grading precision depends on them. This is a practical inference from the part’s documented role in the circle reverse assembly.

Workshops may also keep this type of component in stock because a failed worm gear can affect machine availability and delay roadwork or maintenance schedules.
