FAQs

Q1: How do I verify if this HX35 turbocharger fits my Komatsu D58? 

Please check the nameplate on your current turbocharger for the part number 3802862 or 3593209. Since the Cummins 6CT engine was used in various machines, matching the specific 7-digit OEM part number is the most reliable way to ensure a correct fit.

Q2: Is this turbocharger compatible with the 6BT engine mentioned in some catalogs? 

Yes. The HX35 platform is used for both the 6BT (5.9L) and 6CT (8.3L) engines. However, the housing orientations and flange sizes may vary. This specific SKU is calibrated for the high-airflow requirements of the Komatsu D58 / 6CT application.

Q3: Does it include the mounting gaskets for a 6CT manifold? 

Our standard turbocharger package typically focuses on the unit itself. We highly recommend purchasing a new high-temperature gasket kit for the Cummins 6CT to ensure a perfect, leak-free seal during installation.

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

We understand that dozers operate in high-dust and high-vibration environments, which is why we stand behind our quality with full technical support for machine owners and maintenance 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.
