Detailed Description

The 17A-71-12351 LOCK KOMATSU might appear small in size, but it’s an essential part of Komatsu’s robust mechanical system. Designed to maintain component alignment and prevent movement under high torque or vibration, this lock plate is widely used in areas where operational safety and mechanical integrity are paramount.

This half-moon style lock features four evenly distributed bolt holes, allowing it to be tightly affixed to companion components such as pivot shafts, articulation joints, or mounting flanges. Once installed, it prevents unintended loosening or shifting, safeguarding both equipment performance and operator safety.

The 17A-71-12351 LOCK KOMATSU is manufactured using high-strength carbon steel, which undergoes a thermal hardening process to enhance structural resilience. It is further treated with a corrosion-resistant coating to extend its lifespan in harsh environments like coastal job sites, desert operations, and wet excavation zones.

This locking plate’s flawless CNC finish ensures compatibility with OEM-standard Komatsu equipment, minimizing the risk of play, misalignment, or component fatigue. Ideal for routine maintenance or complete overhauls, this lock plate ensures your Komatsu equipment operates smoothly and safely, no matter the application.

Role in KOMATSU Machinery Systems

In Komatsu equipment, especially in heavy earthmoving machinery, the 17A-71-12351 LOCK KOMATSU performs a critical role in system integrity. It helps:

• Secure Key Assemblies: Locks shafts and rotating elements into place to prevent shift.

• Enhance Operational Safety: Minimizes risk of failure during high-load activities.

• Support Mechanical Alignment: Ensures stable engagement between connected parts.

• Prevent Loosening Under Vibration: Engineered for rugged applications where parts endure shock and repeated motion.

• Prolong Equipment Life: Reduces wear on companion parts by ensuring tight mechanical fitment.

It is especially vital in tracked and blade-mounted Komatsu machines, where powerful forces could otherwise compromise structural stability without secure locking mechanisms.

Maintenance and Replacement Tips

Although built for resilience, the 17A-71-12351 LOCK KOMATSU should be included in regular inspection cycles. Look out for the following signs that a replacement may be needed:

• Cracks or splits near bolt holes

• Warping due to excessive force or corrosion

• Rounded or stripped bolt hole edges

• Loss of contact with adjoining components

When replacing, ensure proper bolt torque is applied and surfaces are free of debris or rust to maintain a secure fit.
