Specification

Description

Advantage

OE-Level Quality Assurance: Adopts the same forging process and material standards as the original parts, made in Japan. Strictly follows OE specifications for dimensional tolerances, enabling direct, non-destructive replacement installation without additional processing or adjustment.
High-Strength Fatigue-Resistant Design: Forged from high-strength alloy steel in one piece, with an optimized rod body cross-section to effectively distribute working stress, improving impact and fatigue resistance for high-load engine conditions.
Precision Wear-Resistant Structure: The small end bushing uses wear-resistant copper alloy material, and the big end bore is precision-honed. Surface roughness is controlled within standard ranges, significantly reducing friction pair wear and extending service life.
Wide Compatibility: Precisely fits mainstream engine models 4JG1, 4JB1, 4JJ1, covering multiple excavator and engineering equipment models. Strong versatility makes it a reliable choice for equipment repair and maintenance.

Performance

Capable of withstanding alternating loads under high-speed, high-load engine conditions, with no risk of rod body deformation or fracture, ensuring stable power transmission.
Accurate fit clearances between the small end bushing and piston pin, as well as between the big end and crankshaft journal, result in low motion friction and effectively reduce engine power loss.
With surface strengthening treatment, it offers excellent corrosion and oxidation resistance, adapting to the complex working environments of construction machinery, with no rust or wear issues after long-term use.
Undergoes strict dimensional inspection and pressure testing before leaving the factory. All performance indicators meet OE standards. After installation, the engine runs smoothly without abnormal noise, vibration or other faults.
