FAQ

Q: Is this turbocharger a direct bolt-on for my Kato excavator with a Mitsubishi 4D31 engine?
A: Yes, this MAHLE TD04-13G (49189-00800) is a direct OEM replacement specifically designed for the Mitsubishi 4D31 engine. It should bolt directly onto the exhaust manifold and connect to the intake system without requiring modifications. However, we always recommend comparing the mounting flange, oil drain, and oil feed pipe positions with your old unit.

Q: What is the difference between this MAHLE turbo and a generic or rebuilt turbocharger?
A: This unit is a 100% new, genuine MAHLE product. Unlike rebuilt or generic units, it uses factory-spec materials (such as high-nickel cast iron for the turbine housing) and precision-balanced rotating assemblies. This ensures longer service life, better reliability, and performance that matches the original engine design.

Q: How should I prepare for installing this new turbocharger?
A: Before installation, ensure the engine oil and filter have been changed. It is critical to prime the turbocharger with clean engine oil by pouring oil into the oil inlet hole and spinning the wheel by hand before starting the engine. Also, inspect the oil supply line for blockages and replace all gaskets and seals. After installation, let the engine idle for a few minutes to ensure proper oil circulation before applying load.
