FAQs

Q1: How do I verify if this HE800FG turbocharger fits my QSK35 engine? 

Please check the nameplate on your current turbocharger for the part number 2837539 or the Komatsu OEM number 6241-82-8200. Since the QSK35 is a large V-block engine, it often uses 2 or 4 turbochargers. We recommend checking the part numbers on all banks to ensure a perfect match for the specific configuration.

Q2: What is the difference between HX83 and HE800FG? 

The HE800FG is the evolved, newer generation designation for the older HX83 platform. It features improved internal sealing and aerodynamic efficiencies while maintaining the exact same mounting dimensions for a seamless "drop-in" upgrade.

Q3: Does this heavy-duty turbo require a special "break-in" procedure? 

For large-displacement engines like the QSK35, it is critical to prime the turbocharger with fresh engine oil before the first start. Ensure that your oil filtration system is new and that there is zero debris in the oil feed lines, as any contamination can instantly damage these high-precision, large-frame bearings.

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

We understand that QSK35 engines power mission-critical equipment where downtime can cost thousands per hour, which is why we stand behind our quality with full technical support for global industrial operators.

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.
