What is the valve clearance for Komatsu engines?

[HoldenLynn]

Komatsu engine valve clearance is measured with the engine at operating temperature, with the intake valve at 0.4 mm and the exhaust valve at 0.6 mm. Below is an introduction to valve clearance: Hazards of insufficient valve clearance: When the engine is running, the valves will expand due to rising temperatures. If there is no gap or insufficient clearance between the valve and its transmission components when cold, thermal expansion during operation will inevitably cause the valve to fail to close tightly. This results in gas leakage during the compression and power strokes, reducing engine power and potentially making the engine difficult to start in severe cases. Introduction to valve clearance: To eliminate this phenomenon, a certain gap is typically maintained in the valve and its transmission mechanism during cold assembly of the engine, compensating for thermal expansion of the valve. This gap is called valve clearance.
