Selecting Exhaust Manifold
Separate the manifold itself from the manifold-to-head gasket and fixing hardware. Include the existing manifold number and a connection-side photo when asking us to check the required part.
Catalog reference: Hitachi ZX120; engine configuration 4BG1-TCG. 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.
