FAQ

Q: How do I confirm this valve guide will fit my specific Kubota Z402 engine?
A: While engineered for the Z402 model, we strongly recommend comparing the physical dimensions of your original valve guide with our provided OEM-size specifications. For absolute certainty, referencing your engine’s serial number and corresponding OEM parts catalog is the best practice before ordering.

Q: What is included with the quality assurance documentation?
A> Each order is accompanied by a formal Machinery Test Report detailing the part’s conformance to specifications. Additionally, you can request the Video Outgoing-Inspection footage, which visually documents the final quality check and packaging of your specific batch before it leaves our facility.

Q: Do you provide technical support for installation?
A> Yes. We offer online support for our products. For complex installation procedures involving valve guide replacement—which typically requires specialized tools like a valve guide driver/reamer and often involves cylinder head reconditioning—we recommend consultation with a certified diesel engine mechanic. We can provide general guidance on part specifications and fitment.
