04020-00514 dowel pin Komatsu bulldozer spare parts

The Komatsu 04020-00514 dowel pin is a precision positioning component for Komatsu bulldozer bodies, shells, covers, gears, and other parts. Manufactured strictly according to Komatsu’s original dimensions and precision standards, it ensures accurate positioning, stable concentricity, and prevents misalignment between assembled components. It is a key standard component for engine, hydraulic system, and transmission system maintenance and overhaul.

The 04020-00514 dowel pin is made of high-strength alloy structural steel, precision ground and heat-treated, resulting in moderate surface hardness, good wear resistance, and high shear strength. It can withstand vibration and impact loads without easily bending, deforming, or breaking. The outer diameter, length, and coaxiality strictly adhere to original factory tolerances, ensuring precise positioning and tight assembly. This effectively guarantees component assembly accuracy and prevents problems such as misalignment, abnormal gaps, and abnormal operating noises.

This product is suitable for various harsh operating conditions of Komatsu bulldozers. It offers reliable positioning, high durability, and effectively improves equipment assembly accuracy and operational stability, reduces the failure rate, and extends the overall machine lifespan.
