FAQ

Q1: How can I confirm this fan blade fits my Yanmar 4TNV98 engine?
A: This fan blade (Part #129920-44740) is specifically designed for the Yanmar 4TNV98 engine series. To confirm fitment, please verify your engine model plate and measure the existing fan blade’s diameter and bolt pattern. If you have any doubts, contact our support team with your engine serial number for cross-reference verification.

Q2: What is the recommended installation procedure for this fan blade?
A: Installation should be performed by a qualified diesel mechanic. Ensure the engine is cool and disconnected from the battery. Remove the old fan blade carefully, noting the mounting orientation. Clean the mounting surface and install the new blade using the correct torque specifications for the mounting bolts. Always check for proper clearance and free rotation before starting the engine.

Q3: How do I maintain this fan blade for optimal performance and longevity?
A: Regularly inspect the fan blade for cracks, deformation, or damage, especially after operating in debris-heavy environments. Keep the blade clean to prevent imbalance. Check mounting bolts for tightness periodically. If you notice excessive vibration or unusual noise from the cooling fan area, inspect and replace the blade immediately to prevent damage to the radiator or fan drive system.
