Construction machinery For 8T-8920 8T8920 BOLT CAT C7.1 Excavator engine parts

Specification

Description

Advantage

• Precise Fit: Manufactured in strict accordance with original factory specifications, with high dimensional accuracy, perfectly suitable for C7.1 engines of corresponding model excavators, with high installation fit, no secondary processing required, and direct replacement of original parts.
• Durable & Rust-proof: Galvanized surface process forms a dense protective layer, effectively resisting oil, water vapor, acid and alkali corrosion, ensuring long-term use without rust and loosening in the harsh working environment of construction machinery.
• High Strength Performance: Forged from high-quality alloy steel, After undergoing a rigorous heat treatment process,with qualified tensile strength and yield strength, withstanding the impact and vibration of high-load operation of the engine, not easy to break and deform.
• High Cost Performance: Original factory quality standard, more advantageous price, while ensuring product consistency and reliability, reducing maintenance costs, is the preferred solution for maintenance replacement.
• Standardized Supply: Standard boxed specifications, clear quantity, convenient for storage and bulk procurement, suitable for daily stock needs of repair shops and construction machinery service providers.

Performance

• Excellent Mechanical Properties: The bolt material meets the standards of high-strength fasteners, with outstanding tensile, shear and fatigue resistance, can withstand the continuous alternating load generated by engine operation, and will not undergo plastic deformation during long-term use.
• Strong Environmental Adaptability: The galvanized layer has excellent protective performance, can work stably in high temperature, high humidity, dusty and corrosive construction site environment, adapts to the full working condition operation needs of excavators, and extends the service life of components.
• High Connection Reliability: High thread accuracy, tight bite, good anti-loosening performance, maintaining a tight state under high-frequency vibration of the engine, avoiding engine failures and potential safety hazards caused by bolt loosening.
• Qualified Processing Accuracy: The dimensional tolerances of the head, rod and thread are strictly controlled, perfectly matching the engine mounting holes, with uniform stress after installation, avoiding component damage caused by local stress concentration.
• Long Service Life: After strict quality inspection and fatigue testing, the product life meets the original factory standards, can be stably used for a long time, reducing maintenance costs and downtime caused by frequent replacement.
