Selecting Crankshaft, Piston and Flywheel
Bearing descriptions and any standard or size notes need to be checked against the engine being repaired. A position in an exploded diagram does not provide the measured journal size or establish which repair specification is required.
Catalog reference: Hitachi EX120-3. Confirm the engine serial number, machine details and complete existing part number before ordering. Different part numbers sharing one diagram position must not be assumed to be interchangeable.
