• YN40F00045F1: Kobelco SK250-8.
• 206-25-00200: Komatsu PC200-7.

Detailed Overview: Also known as slewing rings, swing bearings are essential for the rotational movement of the excavator’s upper structure. They support the load and provide smooth rotation, critical for operations that require precision.

4. Bucket Teeth and Adapters

Function: Bucket teeth and adapters enhance the digging capabilities of the excavator, allowing it to penetrate hard materials efficiently.

Popular Part Numbers:

• 1U3352: Caterpillar J350.
• 20X-70-14160: Komatsu PC200.
• E161-3027RC: Suitable for Volvo EC210.

Detailed Overview: Bucket teeth are wear-resistant components that attach to the excavator bucket. They come in various shapes and sizes, depending on the digging requirements. Adapters are used to secure the teeth to the bucket, ensuring they stay in place during operation.

5. Cylindres hydrauliques

Function: Hydraulic cylinders provide the necessary force to lift, lower, and move the excavator’s boom, arm, and bucket.

Popular Part Numbers:

• 707-01-XZ902: Komatsu PC300-7 Boom Cylinder.
• 223-9732: Caterpillar 320D Arm Cylinder.
• YN02G00037F1: Kobelco SK210-8 Bucket Cylinder.

Detailed Overview: Hydraulic cylinders are actuators that use hydraulic fluid pressure to produce linear motion and force. They are critical for the movement and control of the excavator’s attachments, directly impacting its operational capabilities.

6. Vannes de contrôle

Function: Control valves regulate the flow of hydraulic fluid to various parts of the excavator, ensuring smooth and precise operation.

Popular Part Numbers:

• 31Q6-20310: Hyundai R210-7.
• 102-0999: Caterpillar 320C.
• YN35V00019F1: Kobelco SK200-8.

Detailed Overview: Control valves are essential for directing hydraulic fluid to different actuators within the excavator. They ensure the right amount of fluid reaches each component, enabling precise control over the machine’s functions.

Maintenance and Replacement of Excavator Parts

Proper maintenance of excavator parts is vital to ensure longevity and optimal performance. Here are some tips for maintaining and replacing these critical components:

1. Inspections régulières : Conduct regular inspections to identify any wear or damage early. This can prevent small issues from becoming major problems.
2. Utiliser des pièces de qualité : Always use high-quality, OEM or equivalent parts for replacements. This ensures compatibility and reliability.
3. Follow Manufacturer Guidelines: Adhere to the maintenance schedules and guidelines provided by the manufacturer to keep the excavator in top condition.
4. Lubrification : Ensure all moving parts are adequately lubricated to reduce friction and wear.
5. Professional Servicing: For complex repairs and replacements, engage professional services to ensure the job is done correctly.
