Key Components with Shared Part Numbers
Several critical components are interchangeable between the 992ELC and EX400-3, highlighting the synergy between the two models:
- Hydraulic Oil Cooler: Part number 4333473 is compatible with both the 992ELC and EX400-3, ensuring efficient cooling of hydraulic fluids.
- Idler Pulley: The front idler pulley, part number 9134295, fits both models, contributing to the smooth operation of the undercarriage.
- Bucket Pin: Part number 8039138 is used in both excavators, facilitating secure attachment of the bucket to the linkage.
- Bushing 3026075: This bushing is compatible with both models, playing a vital role in the articulation of the boom and arm.
- Angle Sensor: Part numbers 4716888 and AT154533 are used in both excavators, providing critical feedback for the machine's control system.
While many components are shared, it's essential to consider the following when sourcing parts:
- Model Variations: Ensure that the part number matches the specific model and serial number of your machine, as variations can exist within the same model series.
- OEM vs. Aftermarket: Original Equipment Manufacturer (OEM) parts are recommended for optimal performance and longevity, though high-quality aftermarket parts can be considered for cost savings.
- Component Condition: When replacing parts, assess the condition of related components to prevent premature wear and ensure overall machine reliability.
To maximize the lifespan and performance of shared components:
- Regular Inspections: Conduct routine checks for wear, leaks, and damage to critical components.
- Timely Replacements: Replace worn or damaged parts promptly to prevent further damage and costly repairs.
- Proper Lubrication: Ensure that moving parts are adequately lubricated to reduce friction and wear.
