FAQ

Q: How do I confirm if these valves fit my Kubota V3800 engine?
A: Visually inspect your existing valve for the part number stamped on the stem. The intake valve should show 1C020-13112 and the exhaust valve 1C020-13122. You can also cross-reference your engine serial number, typically located on the engine block near the injection pump. We recommend checking the valve head diameter and stem diameter against our specifications above.

Q: Can I replace only one valve, or should I replace all?
A: For optimal engine balance and compression uniformity, we strongly recommend replacing all intake and exhaust valves (4 of each) as a complete set. If only one valve is damaged, it is acceptable to replace just that single valve, but you should also inspect the corresponding valve guide and seat for wear. Always replace valve stem seals simultaneously.

Q: What maintenance is recommended after installing these valves?
A: After installation, perform a valve clearance (lash) adjustment according to the Kubota V3800 service manual. Typical cold clearance is 0.25-0.30 mm for intake and 0.35-0.40 mm for exhaust. Run the engine at idle for 10 minutes, then re-torque the cylinder head bolts to specification. We recommend using new cylinder head gaskets and valve stem seals during installation.
