FAQ

Q1: Is this cylinder head a complete assembly including valves and springs?

This part is typically supplied as a bare casting. Valves, springs, retainers, and seals are generally not included and must be transferred from your original head or purchased separately. Please confirm with your sales representative the exact scope of supply for your specific order.

Q2: Are the valve guides pre-installed or do I need to machine them to fit?

The valve guides are installed and finish-reamed to exact specifications at the factory. This ensures a proper fit with standard Komatsu valves. No additional machining is required for installation under normal circumstances.

Q3: What is the recommended installation procedure for this cylinder head?

We strongly recommend using a new OEM or high-quality aftermarket cylinder head gasket set and head bolts (or stretch bolts) during installation. Follow the Komatsu service manual for the specific tightening sequence and torque specifications for the SAA6D125 engine to prevent warpage or gasket failure. Always clean the engine block deck surface thoroughly before installation.
