Selecting Camshaft and Valve
Intake and exhaust valves have separate catalog descriptions. Keep the valve type, camshaft components and rocker arm hardware distinct when preparing an enquiry, and include any markings from the removed parts.
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.
