7142314110, 714-23-14110 COUPLING FRONT KOMATSU

Product Overview

The 7142314110, 714-23-14110 COUPLING FRONT KOMATSU is a transmission output coupling assembly used in selected Komatsu GD555, GD655, and GD675 motor graders. Public catalog references identify this part as 714-23-14110 COUPLING ASS’Y and place it in the transmission output section, confirming that it is a drive-related component rather than a general mounting part.

on your website, it is important to include both part-number formats: 7142314110 and 714-23-14110. Buyers often search one format from invoices or ERP systems and the other from printed parts books. At 3GEN Export, we present the 7142314110, 714-23-14110 COUPLING FRONT KOMATSU as an OEM supplier solution with worldwide delivery in 5 working days. The fitment and catalog information below are based on public parts references.

What Is 7142314110, 714-23-14110 COUPLING FRONT KOMATSU?

The 7142314110, 714-23-14110 COUPLING FRONT KOMATSU is a front coupling assembly that belongs to the transmission output group. In practical terms, this means it works in the section where rotational force is transferred onward through the driveline. Public references list it specifically as COUPLING ASS’Y, while related nearby numbers such as 714-16-24110 COUPLING, FRONT and 714-16-14122 COUPLING, REAR appear in associated coupling families, reinforcing its role in power transfer within the grader drivetrain.

From The product images, the part appears to combine a machined internal spline sleeve with a cast and machined housing body and bolting surfaces. That visible geometry suggests a component designed for secure torque transmission, alignment stability, and reliable connection to mating shafts or adjacent transmission elements. This mechanical reading is based on the product photos together with the catalog placement, not on a quoted factory service manual.

Why This Coupling Matters

A front transmission coupling is one of those parts that does not attract attention until wear begins affecting performance. When the correct coupling is installed, torque transfer remains smooth, the mating splines stay properly aligned, and the surrounding output components operate under more controlled load. When the wrong part is used, or when wear progresses too far, problems can show up as play, vibration, poor engagement, abnormal noise, and accelerated wear in connected drivetrain parts.

Because public parts references place 714-23-14110 in the transmission output assembly, it is reasonable to treat this part as a critical driveline connection component. In grader applications where machine uptime is essential, correct spline engagement and housing accuracy help protect the transmission output section from unnecessary mechanical stress.

Compatible KOMATSU Models

I could confirm public model references linking the 7142314110, 714-23-14110 COUPLING FRONT KOMATSU to the following Komatsu grader families:

Confirmed Komatsu model families

• GD555
• GD655
• GD675

Confirmed serial/version references found in public sources

• GD555-3A S/N 10001-UP
• GD655-3C S/N 50001-UP (For North America / Variable Horse Power Type)
• GD655-3E0 S/N 51501-UP
• GD675-3E0 S/N 51301-UP

Because Komatsu applications can vary by serial break and market version, it is best to confirm the exact machine model and serial number before publishing a final fitment claim in your store or before shipping the part to a buyer. The public sources themselves present these applications in serial-based format, so serial verification is the safest commercial practice.

Visual Inspection

7142314110, 714-23-14110 COUPLING FRONT KOMATSU show several details that are useful for product-page buyers.

Internal spline bore

The inner bore is splined, indicating direct connection to a mating shaft for positive torque transfer without slip.

Machined outer sleeve section

The cylindrical outer sleeve appears precision-machined for controlled fit, rotation stability, and proper engagement in the transmission output assembly.

Cast body with mounting ears

The coupling body includes two side mounting sections with threaded bolt holes, showing that it is not just a plain sleeve but a structurally integrated drive assembly.

Flanged lip and sealing area

A visible outer flange or lip around the midsection suggests alignment and interface control with neighboring transmission parts, possibly helping with positioning and assembly retention.
