FAQ

Q: How do I verify this is the correct bearing set for my 4TNE100 engine?
A: First, confirm your engine model is a 4TNE100. Check the existing bearing for the part number (e.g., 719000-02800). If you are rebuilding, the crankshaft journal must be measured to confirm it is still within “Standard” size. If the crankshaft has been ground, you will need an undersize bearing set (e.g., 0.25mm, 0.50mm).

Q: Are there any special installation procedures for these bearings?
A: Yes. Ensure the bearing shells are clean and dry. Apply a thin layer of clean engine oil to the bearing surface and the back of the shell before installation. Do not use grease. Tighten main bearing and connecting rod cap bolts to the manufacturer’s specified torque in the correct sequence. Always use a torque wrench.

Q: What is the expected lifespan of these bearings under normal operating conditions?
A: With proper installation, regular oil changes, and using the correct oil viscosity, these bearings can last for several thousand hours of operation. The primary cause of bearing failure is contamination (dirt or debris in the oil) or oil starvation. Regular maintenance is key to maximizing lifespan.
