FAQs

Q1: How do I verify if this HX30W CHRA fits my Cummins 4BT engine? 

Please check the nameplate on your turbocharger's compressor housing for the part number 3592015 or 3592016. Since the 4BT engine has dozens of industrial variants, matching the 7-digit Holset or Cummins part number is essential. If unsure, provide your Engine Serial Number (ESN) for a free audit.

Q2: Does this unit fit Komatsu excavators with Cummins engines? 

Yes. This CHRA is the direct replacement for Komatsu part 6732-81-8900, which is the Cummins HX30W turbo used in various Komatsu construction machines.

Q3: What makes Zhongke’s cartridges reliable for industrial work? 

Industrial machines operate under constant load. We use genuine K18 nickel-alloy wheels and perform VSR high-speed balancing to ensure our cores can handle the thermal stress and high RPMs of the 4BT engine without premature bearing failure.

Q4: What type of warranty do you provide for industrial-grade parts? 

As a direct manufacturer with nearly 30 years of experience, we provide full technical support for equipment owners and maintenance fleets 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.
