FAQ

Q1: Is this cylinder head a bare casting or a complete assembly?

This is a complete cylinder head assembly. It typically includes pre-installed valve guides, valve seats, and core plugs. However, it does not include the valves, springs, or camshaft unless specified. Please check the listing details or contact us for a full list of included components.

Q2: Can this cylinder head be used on a Kubota D1403 engine in a non-tractor application?

Yes. The D1403 engine is used across multiple Kubota platforms, including industrial generators, skid steer loaders, and construction equipment. As long as the engine model is D1403, this head will fit. We recommend comparing your old head’s casting number and water port locations to ensure a match.

Q3: What is the recommended installation procedure for this part?

Installation should be performed by a qualified mechanic. Key steps include: cleaning the engine block surface, using a new head gasket, lubricating head bolts, and tightening them in the specified sequence to the correct torque (typically in multiple stages). We recommend replacing the head bolts with new ones, as they are often torque-to-yield. Always consult the official Kubota service manual for your specific engine model.
