Detailed Description

The 2A8-70-14370 BUSHING KOMATSU is engineered to enhance the operational integrity of Komatsu excavators, loaders, and dozers. Bushings are critical for maintaining alignment and controlling motion between moving components such as arms, booms, and buckets. When operating under high loads and abrasive conditions, inferior bushings can deform, accelerate component wear, or result in machine downtime. This specific part has been developed with tight tolerances and superior metallurgy, making it an ideal replacement for machines that need to maintain their performance and reliability under the harshest working conditions.

Its precision-machined grooves and lubrication points allow for continuous grease flow, reducing the build-up of heat and friction during high-frequency articulation. The outer shell is hardened to resist scoring and deformation, while the inner bore is treated to reduce galling and extend the lifecycle of the mating pin or shaft.

Role in Excavating Systems

Bushings like the 2A8-70-14370 are strategically located in high-stress pivot points of excavators and loaders. They function as sacrificial components, bearing the brunt of friction and load pressure to protect more complex and expensive machine elements. Over time, as the bushing wears down, it can be replaced without the need to machine or replace mating surfaces, keeping repair costs low and equipment availability high.

In excavators, this bushing typically operates within the boom-arm or bucket link joint assemblies. With every dig and load cycle, these joints experience repetitive forces that can reach thousands of pounds. The bushing reduces metal-on-metal contact, ensuring smooth articulation and prolonging the lifespan of the pivot system.

Maintenance and Replacement

To maintain peak performance of your equipment, regular inspection of the bushing is essential. Below are key maintenance tips for the 2A8-70-14370 BUSHING KOMATSU:

• Lubricate Regularly: Use high-viscosity industrial grease in line with Komatsu service recommendations.

• Inspect for Wear: Check for signs of ovality, scoring, or cracking every 250–500 operating hours.

• Replace Proactively: Don’t wait for failure. Replace when play is detected to prevent damage to pins or housing bores.

• Pair with New Pins: For best performance, always replace bushings and pins together to maintain proper fitment and load distribution.

Replacing this bushing is straightforward due to its press-fit design. Ensure clean mating surfaces before installation, and use a hydraulic press or appropriate driver tool for even force application.
