FAQ

1. How can I confirm that this valve seat fits my engine?

Confirm fitment by checking the part number stamped on your old valve seat. If it matches 6207-11-1431 or 6207-11-1430, this part is a direct replacement for your Komatsu 4D95 engine. You can also cross-reference your engine serial number with our team for verification.

2. Can a valve seat be installed without specialized tools?

Proper installation of a valve seat requires precision. While it is possible to tap in a seat, we strongly recommend using a professional valve seat installer or a press to ensure it is seated squarely and at the correct depth. Incorrect installation can lead to poor sealing or valve clearance issues.

3. What is the recommended maintenance after installing a new valve seat?

After installation, perform a valve lapping procedure to ensure a perfect seal between the new valve and seat. It is also critical to check and adjust valve clearances according to the Komatsu 4D95 engine service manual. A proper break-in period with a full oil change after the first 50 hours of operation is also recommended for rebuilt engines.
