The CAT E120B is a compact and reliable excavator that is often used in construction, demolition, and excavation projects. To keep your CAT E120B running efficiently, sourcing the right parts is essential. This article provides guidance on where to find replacement parts for the CAT E120B, common parts that may need replacing, and tips for proper maintenance to ensure the longevity of your equipment.
Finding Parts for the CAT E120B
When it comes to finding parts for the CAT E120B, operators typically have a few options. However, it’s crucial to choose high-quality replacement parts to avoid further issues down the line.

1. Authorized CAT Dealerships: The most reliable option for obtaining parts for the CAT E120B is through an authorized Caterpillar dealership. These dealerships offer genuine CAT parts that are designed specifically for the E120B. While they may be more expensive than third-party options, genuine parts are usually the best choice for maintaining the machine's performance.
   
2. Online Retailers and Marketplaces: For operators looking to find parts at a potentially lower cost, online retailers such as eBay, Amazon, or specialized heavy equipment parts stores often have a wide range of aftermarket and used parts. While cheaper, these parts may not always provide the same durability and warranty as genuine CAT parts.
   
3. Salvage Yards and Equipment Auctions: Used parts from salvage yards or equipment auctions can be a cost-effective option for finding rare or discontinued parts. However, it’s essential to thoroughly inspect these parts for wear and tear before purchasing.
   
4. Aftermarket Suppliers: Aftermarket suppliers can provide parts that are compatible with the CAT E120B but may not always match the original manufacturer’s standards. These parts can be a more affordable alternative, but they might not offer the same lifespan or performance as OEM parts.
   

Common Parts that Need Replacing
As with any machine, the CAT E120B will eventually require certain parts to be replaced due to wear and tear. Some of the most common parts that may need replacing over time include:

1. Hydraulic Filters: Regularly changing hydraulic filters is critical to maintaining the health of the hydraulic system. These filters protect the pump and valves from dirt and debris, ensuring smooth operation.
   
2. Track Components: The tracks, rollers, and sprockets on the CAT E120B will inevitably wear out with heavy use. Replacing these components when they begin to show signs of wear can prevent further damage and improve machine stability.
   
3. Engine Parts: Parts such as air filters, fuel filters, and exhaust systems often require replacement as they accumulate dirt and contaminants. Regular maintenance and timely replacements will keep the engine running at optimal efficiency.
   
4. Seals and Gaskets: Seals and gaskets on the hydraulic and engine systems are prone to wear and can cause leaks if not replaced. Regularly inspect and replace seals as needed to avoid hydraulic fluid leaks and maintain pressure.
   
5. Electrical Components: As the CAT E120B is equipped with various sensors and electrical systems, issues such as faulty wiring or malfunctioning sensors can occur. Replacing faulty components promptly can prevent further electrical issues and improve machine performance.
   

Maintenance Tips to Extend the Life of Your CAT E120B
Proper maintenance is the key to getting the most out of your CAT E120B excavator. Below are some essential maintenance tips to keep your equipment in top condition:

1. Regularly Check Fluid Levels: Ensure that hydraulic fluid, engine oil, and coolant are all at the proper levels. Low fluid levels can lead to overheating and potential damage to internal components.
   
2. Clean or Replace Air Filters: Clogged air filters can reduce engine efficiency and lead to overheating. Regularly clean or replace the air filters to ensure that the engine receives adequate airflow.
   
3. Inspect Hydraulic Systems: Hydraulic systems should be inspected regularly for leaks or pressure issues. Addressing minor hydraulic issues early can prevent major repairs down the line.
   
4. Grease Moving Parts: Grease moving parts such as joints and bearings regularly to ensure smooth operation and reduce the risk of premature wear.
   
5. Check Tracks and Undercarriage: Inspect the tracks, rollers, and undercarriage for wear and tear. Ensure that they are properly tensioned and replace any worn-out parts promptly to avoid costly repairs.
   

Conclusion
Finding the right parts for your CAT E120B is essential to maintaining its performance and extending its lifespan. Whether you choose to purchase parts through authorized dealers, online retailers, or aftermarket suppliers, it’s important to prioritize quality. Regular maintenance and timely part replacements will keep your CAT E120B excavator running smoothly, allowing you to get the most out of your investment.
