FAQ

Q: How can I confirm this S4L crankshaft will fit my engine?
A: Please verify the engine model stamped on your engine block. This part is specifically designed for the Mitsubishi S4L diesel engine. If your equipment uses this engine, the crankshaft should be a direct fit. For further confirmation, you can compare the dimensions with your old part or contact us with your engine serial number.

Q: What is the recommended installation procedure for this crankshaft?
A: Installation should be performed by a qualified diesel mechanic. We recommend cleaning the engine block thoroughly, inspecting main bearings for wear, and applying proper assembly lubricant. The crankshaft must be torqued to the manufacturer’s specifications (typically found in the service manual). Ensure the thrust bearing is correctly aligned to prevent axial play.

Q: Does this crankshaft come with bearings or seals?
A: This listing is for the crankshaft only. Main bearings, thrust washers, and seals are sold separately. We recommend replacing all bearings and seals during a rebuild to ensure optimal performance and longevity of the new crankshaft.
