FAQs
Q1: How do I verify if this turbocharger fits my DH300-5 excavator?
Please check the nameplate on your current turbocharger for the part number 466721-5007S or the Doosan number 65.09100-7038. Matching these numbers is the most reliable way to ensure 100% fitment for the D1146TI engine.
Q2: What is "K18 Nickel-Alloy" and why is it critical for construction machinery?
K18 is a specialized high-nickel alloy used for turbine wheels. It is designed to maintain its shape and structural strength at exhaust temperatures exceeding 900°C. This is vital for excavators that operate under continuous high load in mining and construction sites.
Q3: What maintenance is required for a new D1146TI turbocharger?
For construction equipment, we recommend replacing the Air Filter and Engine Oil/Filter during installation. Dust ingestion is the #1 cause of turbo failure in excavators. Always prime the turbo with fresh oil before the first start to protect the precision bearings.
Q4: What type of warranty do you provide for heavy industrial use?
We understand that machine downtime is extremely costly in construction, 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.
