FAQ

Q: Will this bearing set fit my Mitsubishi 6D31 excavator engine?
A: This set is specifically designed for Mitsubishi 6D31 and 4D31 engines. However, we recommend cross-referencing your existing bearing part numbers (look for M132H or similar markings on your old bearings) to confirm compatibility. If you have the engine serial number, please contact us for further verification.

Q: What is included in this bearing set?
A: The set includes both the main bearings (part number M132H) and the con rod bearings. It does not include thrust washers or other engine components. Please ensure your engine’s specific configuration matches this set before installation.

Q: How should I install these bearings for best performance?
A: Proper installation is critical. Clean all bearing surfaces thoroughly and apply clean engine oil to the bearings before assembly. Use a torque wrench to tighten main bearing and con rod bolts to the manufacturer’s specifications. After installation, check crankshaft rotation for smooth movement.
