FAQ

Q1: Is this a full set of bearings for a complete engine rebuild?
A1: Yes, this Taiho M132H set includes both the main bearings (which support the crankshaft in the engine block) and the connecting rod bearings (which connect the rods to the crankshaft), providing the essential bearings for a standard in-chassis or out-of-chassis overhaul.

Q2: How do I confirm this is the correct bearing set for my specific Mitsubishi 6D31 engine?
A2: The most accurate method is to cross-reference the part number stamped on your old bearings or consult the engine’s official service parts manual. The Taiho number M132H is the key identifier. Ensure your crankshaft journal sizes are standard; if it has been reground, you will need undersize bearings.

Q3: What are the installation precautions for these bearings?
A3: Always clean all engine oil passages and components thoroughly. Verify bearing clearances with Plastigage or a micrometer during installation. Use the recommended engine oil and torque the bearing caps to the manufacturer’s specified values in the correct sequence. Proper installation is critical for longevity.
