FAQs

Q1: How do I verify if this CHRA fits my CAT 320 excavator? 

Please check the nameplate on your current turbocharger for the Mitsubishi part number 49179-02260 or the CAT number 5I-7952. Since the S6K engine has several turbo variations, matching the specific 10-digit Mitsubishi or 6-digit CAT number is the most reliable way to ensure fitment.

Q2: Can I install this cartridge myself, or do I need special equipment? 

This CHRA comes pre-balanced from the factory. You simply need to swap your original compressor and turbine housings onto this new core. No additional balancing is required. However, we recommend a clean environment and replacing all oil gaskets during the swap.

Q3: What maintenance is critical for CAT 3066T turbochargers? 

Caterpillar engines are built to last, but turbos require clean oil. Ensure you use high-quality engine oil and change your filters regularly. Before starting the machine after installation, we highly recommend priming the turbo with fresh oil to prevent "dry start" bearing damage.

Q4: What type of warranty do you provide for heavy excavation work? 

We understand that excavators are the backbone of the job site, which is why we stand behind our quality with full technical support for equipment owners and maintenance workshops worldwide.

Q5: Do you provide worldwide shipping? What is the delivery timeframe? 

We ship globally via premium carriers like DHL, FedEx, and UPS, as well as sea freight for bulk orders. In-stock items are typically dispatched within 24–48 hours. Express delivery to North America and Europe usually takes 5–7 business days.
