FAQ

Q1: Are these valves a direct fit for my Komatsu 4D94 engine?
A: Yes, these valves are manufactured to the exact OEM specifications of the Komatsu 4D94 engine. They are a direct bolt-in replacement for the original intake (6136-41-4110) and exhaust (6136-41-4210) valves. Always verify your engine model and serial number to ensure correct fitment.

Q2: Do I need to replace both the intake and exhaust valves at the same time?
A: While it is not strictly mandatory, it is highly recommended to replace both valves in a set. This ensures balanced wear, consistent compression, and optimal performance across all cylinders. Replacing only one valve can lead to uneven performance or premature failure of the other.

Q3: What maintenance should I perform when installing new valves?
A: For best results, we recommend having the valve seats ground or cut to ensure a perfect seal with the new valves. You should also replace the valve stem seals and check the valve guides for wear. Proper valve lash (clearance) adjustment is critical after installation to prevent engine damage. Always refer to the Komatsu service manual for your specific engine model.
