FAQ

Q1: How can I confirm this supercharger will fit my Komatsu DH300-5 excavator?
A1: The surest method is to cross-reference the part number stamped on your existing supercharger assembly. The primary compatible numbers are 65.09100-7038 and 466721-5007. Providing your machine’s serial number can also allow us to perform a final verification.

Q2: Is this a complete, ready-to-install assembly?
A2: Yes, this is supplied as a complete supercharger (turbocharger) assembly. It includes the core compressor and turbine housing, center cartridge, and actuator as required for a direct bolt-on replacement, minimizing downtime.

Q3: What are the recommended steps after installation?
A3: After installing a new supercharger, it is critical to prime the oil system by cranking the engine without starting (if possible) to ensure oil reaches the turbo bearings. Upon first start, allow the engine to idle for several minutes. Avoid high engine loads or rapid shutdowns for the first operational hour to ensure proper lubrication and seating of components.
