FAQ

Q: How can I be sure this crankshaft (13411-78300-71) fits my engine?
A: This crankshaft is specifically manufactured for the Toyota 1Z diesel engine. To confirm fitment, please check the engine model tag on your machinery and compare it to your existing crankshaft’s part number. If the number on your old part matches 13411-78300-71, this is a direct replacement. We recommend verifying the number of main bearing journals (typically 5 for the 1Z engine) before ordering.

Q: What other parts should I replace when installing a new crankshaft?
A: For a successful rebuild, we strongly recommend replacing the following items simultaneously: main bearings, connecting rod bearings, thrust washers, and the rear main seal. Using new bearings with a used crankshaft can lead to premature failure due to uneven wear patterns. Always check the crankshaft end-play and journal clearances during installation.

Q: Is the crankshaft ready to install out of the box?
A: The crankshaft is manufactured to OEM size and specifications. However, as a best practice in diesel engine rebuilding, we recommend having a qualified machinist check the journal diameters and surface finish upon receipt. While we ensure high quality, final inspection for micro-cracks or shipping damage should always be performed by the installer. Lubricate all bearing surfaces with clean engine oil before assembly.
