FAQ
Q: How do I confirm that this intake valve (3803515) fits my specific K19 engine?
A: To ensure a correct fit, locate the part number on your old valve or consult your engine’s parts manual. The numbers 3803515, 207241, and 308839 are the direct OEM references. If your engine has a different number, please contact us with your engine serial number and the existing part number for cross-verification.
Q: What is the installation procedure for this intake valve?
A: Installation requires standard engine overhaul tools. The valve should be installed with a new valve guide and seal. Ensure the cylinder head is clean and the valve seat is properly ground. Always torque the valve keepers and spring retainers to the manufacturer’s specifications. We recommend consulting a professional diesel mechanic for installation.
Q: What is the recommended maintenance interval for this component?
A: As a non-moving part, the intake valve is designed for the life of a major overhaul cycle. However, it is critical to inspect valves during any top-end overhaul (typically every 10,000-15,000 hours for industrial K19 engines). Look for signs of stem wear, pitting on the seat face, or carbon buildup. Replace valves in sets to ensure uniform performance.
