Detailed Description
The 175-71-21230 PLATE KOMATSU plays a crucial role in reinforcing mechanical stability and component alignment across Komatsu’s mid-size to heavy-duty machinery. Characterized by its thick steel build, symmetrical bolt hole pattern, and U-shaped central cut-out, this locking plate is specifically engineered to secure high-stress pivot zones and assembly interfaces.
Designed for durability and performance in punishing environments, this plate is machined to ensure exact fitment with factory torque values and mechanical tolerances. It provides the crucial rigidity needed to prevent structural shifting, rotational displacement, and bolt loosening under stress.
Its yellow oxide coating not only matches the aesthetic profile of Komatsu’s color standards but also functions as a protective barrier against rust, mud, debris, and corrosive elements often found in off-road and excavation work environments.
When installed, the 175-71-21230 PLATE KOMATSU acts as a load spreader across bolted connections—minimizing stress concentration and extending the life of adjoining components such as brackets, joints, and pins. Its compatibility with Komatsu’s undercarriage and blade systems makes it indispensable for maintaining optimal performance and structural cohesion.
Key Features
• High Durability: Built from heavy-duty steel to withstand continuous vibration and impact.
• Corrosion Protection: Yellow oxide coating shields the plate in wet or chemically harsh conditions.
• Precision Fitment: Bolt holes and edges machined to OEM-grade tolerances.
• Easy Installation: No modifications required—fits directly into existing bolt patterns.
• Secure Reinforcement: Ideal for joints, pivots, and connections prone to structural wear.
• Reduced Maintenance Costs: Prevents early failure of costly primary parts.
• Worldwide Shipping: Available globally from 3GEN Export with 5-day delivery.
• Versatile Application: Used in various high-torque and load-bearing Komatsu systems.
Compatible KOMATSU Models
The 175-71-21230 PLATE KOMATSU is compatible with several widely used Komatsu bulldozers and tracked machines. These include:
• Komatsu D155AX-6 Bulldozers
• Komatsu D155A-5 and D155A-6 Series
• Komatsu D275A-2 Crawler Dozers
• Komatsu D375A Series Heavy-Duty Dozers
• Komatsu D475A Series Earthmoving Bulldozers
It is most commonly installed in track frame locking mechanisms, blade push arm supports, and torque-bearing chassis locations where reinforced fastening is essential.
Always refer to your Komatsu service manual or consult 3GEN Export to verify part compatibility for your machine’s model year and configuration.
Role in KOMATSU Machinery Systems
In Komatsu machines, particularly large bulldozers, the 175-71-21230 PLATE KOMATSU performs as a lock and reinforcement plate. Its key roles include:
• Locking Blade Frames or Push Arms: Ensures structural integrity at high-stress joint interfaces.
• Securing Track Frame Assemblies: Prevents frame flex and misalignment under load.
• Distributing Load Pressure: Protects the machinery’s frame from concentrated stress.
• Protecting Structural Components: Prevents premature failure of mounting brackets and pins.
• Stabilizing Vibration-Prone Connections: Minimizes mechanical loosening over time.
Its performance under high pressure and frequent motion makes this component essential in any major Komatsu equipment overhaul or track frame rebuild.
Maintenance and Replacement
Even with its rugged construction, the 175-71-21230 PLATE KOMATSU should be inspected regularly during equipment maintenance, especially in high-load environments.
Signs that replacement is required:
• Surface cracks or deformation
• Enlarged or warped bolt holes
• Corrosion or rust compromising the structure
• Signs of metal fatigue or loss of tension retention
Replacement Process:
Unbolt the existing lock plate, inspect surrounding components for wear, install the new plate, and reapply bolts to Komatsu torque specifications.
For best results, always replace this component in pairs or alongside its associated bolts and lock washers to restore full mechanical integrity.
