FAQs

Q1: How do I verify if this TD04HL-15G turbocharger fits my machine? 

Please check the nameplate on your current turbocharger for the part number 49189-00540 or the Isuzu OEM number 8971159720. Since the 4BG1T engine was used in hundreds of different configurations, matching the specific OEM part number is the most reliable way to ensure a correct fit.

Q2: Does this turbocharger require specific installation procedures for JCB excavators? 

Yes. For industrial machines, it is critical to prime the turbocharger with fresh engine oil before the first start. Additionally, ensure your Air Filter and engine oil/filter are new. In dusty construction environments, a clogged air filter can create a vacuum that causes the turbo to leak oil past the seals.

Q3: What is the benefit of the K18 Nickel-Alloy turbine wheel? 

The K18 alloy is designed specifically for high-stress, high-heat environments. It allows the turbine blades to maintain their shape and efficiency even at high temperatures, preventing catastrophic failure and maintaining boost consistency during heavy digging or lifting.

Q4: What type of warranty do you provide for heavy industrial use? 

We understand that excavators and industrial trucks are the backbones of your business, which is why we stand behind our quality with full technical support for machine owners and professional 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.
