FAQs

Q1: How do I verify if this HT4B turbocharger fits my Cummins VTA28 engine? 

Please check the nameplate on your current turbocharger for the part number 3523591 or the Cummins OEM number 3802590. Since the VTA28 engine is a V12 configuration, it often utilizes two turbochargers. We recommend replacing both units or verifying numbers on both banks to ensure a perfect match.

Q2: What is the difference between NX and RX suffixes in Cummins part numbers? 

NX typically indicates a "New Exchange" part, while RX indicates a "Remanufactured Exchange" part. Our product is a brand-new, direct replacement that meets the same high technical standards as the original "New" unit, providing superior longevity over remanufactured alternatives for critical power operations.

Q3: Does this turbocharger require specific installation procedures for generator sets? 

Yes. For high-displacement engines like the VTA28, it is critical to prime the turbocharger with fresh engine oil before the first start. Additionally, ensure that the oil lines and filters are new to prevent any debris from entering the high-precision bearing housing during initial run-up.

Q4: What type of warranty do you provide for remote mining and power gen sites? 

We understand that VTA28 engines are often located in remote areas where downtime is extremely costly, which is why we stand behind our quality with full technical support for industrial operators 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.
