FAQ
Q: How do I confirm this valve seat will fit my specific Komatsu machine?
A: The primary fitment is based on the engine model. You must verify that your equipment is powered by a Komatsu 4D94 diesel engine. The engine model is typically stamped on the engine block or listed in the equipment’s service manual. Cross-reference the part numbers 6209-11-1440 or 6209-11-1430 with your machine’s parts catalog for absolute certainty.
Q: What is the recommended installation procedure for this valve seat?
A: Valve seat installation is a precision engine rebuilding task. It typically requires machining the cylinder head counterbore to the correct interference fit, followed by chilling the seat and heating the head for proper installation (shrink-fit method). We strongly recommend installation by a qualified mechanic using proper tools and specifications to ensure correct depth, alignment, and sealing.
Q: Do you provide technical support or documentation for this part?
A> While we supply the component to OEM specifications, detailed installation torque values, clearance specs, and step-by-step procedures should be obtained from the official Komatsu 4D94 engine service manual. We can provide general dimensional data and the pre-shipment inspection report for quality verification.
