In heavy-duty operations, even the smallest components can significantly impact the performance and lifespan of machinery. One such critical part is the bushing, which ensures smooth joint movement and minimizes wear in high-stress zones. For the Komatsu D375 bulldozer, the MASSCoT Bushing 195-30-34121 is an exceptional replacement part, designed with durability, precision, and compatibility in mind.
This brand-new, in-box bushing is a direct-fit alternative to the Komatsu OEM part number 195-30-34121 and is engineered to meet the highest standards under the MASSCoT Original line—trusted for long-lasting performance in the most demanding environments.
What Is the Role of a Bushing in a Bulldozer?
Bushings are mechanical components designed to reduce friction between moving parts—most commonly at joints, pivot points, and high-contact surfaces. In the Komatsu D375, a heavy-duty bulldozer used in mining, construction, and land development, bushings play a key role in:
-
Ensuring proper articulation of the undercarriage and blade linkage
-
Reducing vibration and wear
-
Extending the service life of larger structural components
-
Providing a buffer between hardened metals
Worn-out bushings can lead to operational instability, increased maintenance costs, and premature failure of adjacent parts. That’s why using a high-precision bushing like MASSCoT’s 195-30-34121 is essential for long-term equipment health.
MASSCoT Bushing 195-30-34121 – Built for Performance
✅ OEM-Equivalent Precision
MASSCoT bushings are precision-machined to meet or exceed Komatsu’s OEM specifications. This guarantees a perfect fit into the D375 dozer’s mounting locations and optimal performance under real-world working conditions.
✅ High-Strength Materials
Each bushing is made from heat-treated alloy steel for enhanced wear resistance and load-bearing strength. The material composition ensures that the bushing can endure repetitive stress, shock loads, and the impact of continuous operation.
✅ Smooth Internal Surface Finish
The internal bore is honed to a fine finish to reduce friction against mating pins or shafts. This improves efficiency and contributes to a quieter and smoother operation of your Komatsu dozer.
✅ Corrosion & Contaminant Resistance
With added surface treatments and protective packaging, this product arrives brand new in box and ready for installation—free from rust, dirt, or mechanical damage.
Application – Komatsu Dozer D375
The Komatsu D375 is a large crawler dozer used extensively in mining and heavy construction. Its components are under constant pressure from:
-
Heavy dozing loads
-
Repetitive ground engagement
-
Harsh terrains and debris
The 195-30-34121 bushing supports moving joints—particularly in the undercarriage and blade assembly—where pivot motion and load resistance are required. By using the MASSCoT alternative, operators can reduce machine downtime, lower operational costs, and extend maintenance intervals.
