FAQ

Q1: How do I confirm this crankshaft fits my engine?
A1: Fitment is determined by the engine model and part number. Your engine must be a Mitsubishi 6DB10. We strongly recommend checking the part number 30017-90000 on your existing crankshaft or in your engine’s service manual. If you have a different part number, please contact us with your engine serial number for cross-referencing.

Q2: What is the installation procedure for this crankshaft?
A2: Crankshaft installation is a complex procedure requiring specialized tools and mechanical expertise. We recommend installation by a certified diesel mechanic. Key steps include: cleaning the block, installing main bearings, carefully lowering the crankshaft, torquing main bearing caps to the correct specification, and checking end-play. Always use new bolts and follow the Mitsubishi 6DB10 service manual for precise torque values and sequences.

Q3: How should I maintain the new crankshaft after installation?
A3: Maintenance primarily involves proper lubrication and regular oil changes. Use the engine manufacturer’s recommended oil grade and change intervals. During the initial break-in period (first 50 hours), avoid heavy loads and high RPMs. After installation, always check for unusual vibrations or noises, which could indicate a balance issue. Regular oil analysis can help detect early signs of bearing wear.
