FAQs

Q1: How do I verify if this TD04L turbocharger fits my PC70-8? 

Please check the nameplate on your current turbocharger for the part numbers 6271-81-8500 or 49377-01760. These are the primary identifiers. If you are unsure, please provide your Machine Serial Number to our support team for a free fitment audit.

Q2: Is this turbocharger a direct fit for the 3.3L engine? 

Yes. This is a 100% "drop-in" direct replacement. All mounting points, oil inlets, and air connections are identical to the original factory unit, ensuring a quick installation to get your machine back to work.

Q3: What makes Zhongke’s small excavator turbos more reliable? 

Unlike low-cost alternatives, we use genuine K18 nickel-alloy for our turbine wheels and perform VSR high-speed balancing. This is critical for small turbos because they spin at very high speeds; precision balancing prevents premature bearing failure.

Q4: What type of warranty do you provide? 

As a direct manufacturer with nearly 30 years of experience, we understand that reliability is key for your fleet and provide full technical support.

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.
