FAQ

Q: How do I confirm if this rocker arm assembly fits my engine?
A: First, verify your engine model is a Komatsu 4D95 (e.g., 4D95-1, 4D95-L). Then, locate the part number on your old rocker arm assembly or your engine’s parts manual. If it matches 6206-41-5210, this part is a direct fit. If you have a different number, please contact us with your engine serial number for cross-reference assistance.

Q: What are the signs that my rocker arm assembly needs replacement?
A: Common symptoms include a ticking or tapping noise from the valve cover area, reduced engine power, rough idling, or poor fuel economy. Visually, you may see excessive wear on the contact pad where the rocker arm meets the valve stem, or looseness at the pivot point. If you notice these issues, replacing the assembly can restore proper valve clearance and engine performance.

Q: Is any special maintenance required after installing this new rocker arm assembly?
A: After installation, it is critical to adjust the valve lash (clearance) to the manufacturer’s specifications for the 4D95 engine (typically intake: 0.25mm, exhaust: 0.30mm for a cold engine). Use a feeler gauge to check the gap between the rocker arm and the valve stem. Re-check the clearance after the engine has been run and cooled down for the first time to ensure optimal performance and prevent valve damage.
