FAQ

Q: How do I confirm this 6LTAA crankshaft will fit my engine?
A: Check the engine model plate on your Cummins 6LTAA engine. Verify the engine serial number and compare the crankshaft’s main journal and connecting rod journal dimensions to your original part. If you have the OEM part number (e.g., 3935802), it can be cross-referenced directly.

Q: What is the recommended installation procedure?
A: Professional installation by a qualified diesel mechanic is recommended. Ensure the crankshaft is properly lubricated during assembly, main bearing caps are torqued to manufacturer specifications, and the crankshaft end-play is checked. Always replace main bearings and thrust washers when installing a new crankshaft.

Q: How should I maintain the crankshaft after installation?
A: Maintain proper engine oil levels and change oil and filters at recommended intervals. Use high-quality diesel engine oil (e.g., API CJ-4 or CK-4) to protect bearing surfaces. Regularly inspect for unusual vibrations or knocking sounds, which may indicate bearing wear or imbalance.
