PARTS DESCRIPTION
Product Overview
The crankshaft converts the pistons’ reciprocating movement into rotational output and carries repeated combustion loads through its main and connecting rod journals. When servicing Mitsubishi S4S diesel engine applications, choosing the correct crankshaft requires more than matching appearance alone. The S4S crankshaft is supplied for verified replacement applications.
Because selection depends on journal dimensions, stroke configuration, flange and gear interfaces, bearing specification, and part number, confirming the exact configuration before installation is important. Where an OEM reference is listed, use it with the component and model information as a cross-check.

Why This Part Matters
In practical repair work, accurate fitment affects both installation and the relationship with surrounding components. Correct journal dimensions, bearing fitment, stroke configuration, and balance relationship are essential for smooth rotation and stable support inside the engine block. A crankshaft with the wrong journal size, flange configuration, gear interface, or engine version may not fit the existing bearings and connected components correctly.
Compare the replacement with the part before assembly, especially where dimensions, interfaces, or version changes may affect fitment.
