FAQ

Q: Is this bearing set suitable for a standard rebuild of my 4HG1 engine?
A: Yes, this is a Standard Size (STD) main bearing set. It is designed for use with a standard (un-ground) crankshaft journal. If your crankshaft has been reground, you will need an undersized bearing (e.g., 0.25mm or 0.50mm). Always measure your crankshaft journals first.

Q: What is the difference between a main bearing and a connecting rod bearing?
A: Main bearings support the crankshaft within the engine block, while connecting rod bearings fit between the connecting rod and the crankshaft journal. This product listing is specifically for main bearings. You will need a separate set of connecting rod bearings for a complete overhaul.

Q: How should I store these bearings before installation?
A: Store the bearings in their original packaging in a clean, dry environment at room temperature. Keep them away from dust, moisture, and direct sunlight. Do not unwrap them until you are ready to install to prevent contamination or damage to the precision surface.
