FAQ
Q: How can I confirm this flywheel gear fits my engine? A: Check the OEM part number stamped on your existing flywheel gear. If it reads 6741-31-4180, this part is a direct replacement. Also, verify your engine model is a Komatsu 6D114, 6D108, or 6D125. If you are unsure, please contact us with your engine serial number for verification.
Q: What is the installation procedure for this flywheel gear? A: Installation should be performed by a qualified diesel mechanic. The process generally involves removing the transmission, unbolting the old flywheel, and pressing the new ring gear onto the flywheel. This is a precision component; ensure proper alignment and torque specifications are followed to avoid starter or engine damage.
Q: How should I maintain the flywheel gear for optimal performance? A: The flywheel gear itself requires no direct maintenance. However, ensure the starter motor is in good working condition and that the starter bendix engages smoothly. Regularly inspect the ring gear teeth for excessive wear or chipping, and replace the gear if any damage is found to prevent starting failures.
