Detailed Description

The 207-70-72351 BUSHING KOMATSU is specifically engineered to support the articulated joints within hydraulic excavators. Designed with a robust flange and cylindrical housing, this bushing is manufactured using advanced CNC machining and undergoes stringent quality control to meet OEM standards.

Its primary function is to provide a low-friction interface between metal parts, such as the pin and housing, effectively minimizing direct contact. This reduces operational noise, prevents mechanical binding, and ultimately extends the lifespan of both the bushing and associated components.

Its application within KOMATSU excavators is critical for managing dynamic loads encountered during digging, lifting, and traversing rough terrain. The bushing supports smooth rotational motion under pressure and helps preserve alignment within the linkage system—vital for both performance and safety.

Role in Excavator Systems

Bushings such as the 207-70-72351 are indispensable in high-load pivot locations like boom-to-arm and bucket-to-arm connections. Their main function is to:

• Reduce friction between moving components

• Ensure proper alignment of the pin and housing

• Act as a sacrificial wear component that protects higher-cost parts

• Enhance the precision and stability of movement under load

A worn or damaged bushing can lead to play in the linkage system, compromised digging precision, and accelerated wear on pins and brackets. Replacing this bushing in a timely manner helps maintain mechanical health and prevent expensive repairs.

Maintenance and Replacement Guidelines

• Inspection frequency: Every 250–500 operating hours, or as per OEM service intervals

• Common signs of wear:

• Increased pin play

• Noise during articulation

• Grease leakage

• Recommended tools: Hydraulic press, bushing driver set, and alignment jigs

• Replacement interval: Typically every 2000–3000 hours depending on application severity

Using compatible lubricants and performing regular inspections will significantly extend service life and ensure optimal machine performance.
