OEM-Level Fitment High-Strength Material Wear & Fatigue Resistance Piston Pin

Product Specification

For MX913790 Piston PIN Mitsubishi 4D34 6D34 Excavator engine parts

Specification

Description

This piston pin (Part No. MX913790) is a dedicated component designed for 4D34/6D34 series engines in excavators. As the critical connection between the piston and connecting rod, it undertakes the core function of transmitting combustion pressure to drive the crankshaft. Manufactured to OEM-level standards, it precisely matches the corresponding engine models and can directly replace original parts to ensure stable operation of the engine's power transmission system.

Advantage

OEM-Level Fitment: Produced in strict accordance with original specifications, with minimal dimensional tolerance. No additional machining is required during installation, ensuring direct compatibility with 4D34/6D34 engines and preventing wear or abnormal noise caused by improper fit clearance.
High-Strength Material: Made of high-quality alloy steel, through precision forging and heat treatment processes, it combines high hardness and strong toughness, capable of withstanding high-frequency impact and alternating loads during engine operation, resisting deformation and fracture.
Wear & Fatigue Resistance: The surface undergoes special hardening treatment, significantly improving wear resistance and fatigue resistance, reducing wear on the piston pin bore and connecting rod bushing, extending the engine overhaul cycle and lowering maintenance costs.
High Stability: High machining accuracy and excellent surface finish effectively reduce friction resistance, ensuring the coaxiality of piston and connecting rod movement, avoiding eccentric wear and jamming, and maintaining smooth engine operation.

Performance

Dimensional Accuracy: Strictly matches the engine's original design dimensions, ensuring the fit clearance with the piston pin bore and connecting rod bushing meets standards for efficient and stable power transmission.
Load-Bearing Capacity: Capable of withstanding high-pressure combustion loads and high-frequency reciprocating impacts under the engine's rated working conditions, with no risk of plastic deformation, suitable for heavy-duty excavator operations.
Wear Resistance: High surface hardness and low friction coefficient result in minimal wear during long-term operation, effectively preventing engine knocking and power loss caused by excessive piston pin wear.
Reliability: Passes rigorous working condition simulation tests, with excellent high-temperature resistance and impact resistance. It maintains stable performance under complex working conditions, ensuring long-term continuous engine operation.
