Frequently Asked Questions (FAQs)
Q: How to choose the right excavator track roller?
A: Consider your excavator model (e.g., Komatsu PC55), operating conditions, and the type of roller (single or double flange). Always verify with the part number or your machine's serial number.
Q: What is the difference between OEM and aftermarket heavy truck parts?
A: OEM (Original Equipment Manufacturer) parts are made by the truck's original manufacturer. Aftermarket parts are made by other companies. Aftermarket parts, like those offered by Growshine, can be a cost-effective alternative while maintaining quality, especially for heavy duty truck brake pads supplier and truck suspension parts supplier needs.
Q: How often should I replace my excavator hydraulic filter?
A: Replacement intervals depend on the manufacturer's recommendations and operating conditions. Regular replacement of filters (like for the Komatsu PC55 hydraulic pump) is crucial for hydraulic system longevity and preventing costly failures.
Troubleshooting: Excavator Loss of Hydraulic Power
Problem: Your Komatsu PC56 excavator experiences a significant loss of hydraulic power, movements are slow or weak.
Possible Causes: Low hydraulic fluid level, clogged hydraulic filter, worn hydraulic pump (e.g., PC55 hydraulic pump), faulty control valve, or engine performance issues.
Basic Steps:
- Check the hydraulic fluid level and add fluid if necessary.
- Inspect and replace the hydraulic filter if it's clogged (applicable for Komatsu PC60/70-8MO PC78US PC78MR-6-8 hydraulic return filter).
- Listen to the hydraulic pump for unusual noises.
- Check engine performance to ensure it's running correctly.
- If these steps don't resolve the issue, the problem may lie within the hydraulic pump assembly or control valve assembly and requires professional diagnosis and repair.
