Installation Notes

  1. Ensure the engine is turned off and disconnected from the power source before beginning work.
  2. Access the engine block and crankshaft according to your engine's service manual. This typically requires significant disassembly.
  3. Carefully remove the old bearing halves, noting their orientation and position.
  4. Clean the crankshaft journal and the bearing saddle in the engine block meticulously.
  5. Lubricate the new bearing half with clean engine assembly lube or oil.
  6. Install the new bearing half, ensuring it is seated correctly and the locating tabs are properly aligned.
  7. Reassemble the engine components in the reverse order of disassembly, torquing all bolts to the manufacturer's specifications.
  8. After reassembly, prime the oil system before starting the engine to ensure adequate lubrication.

Troubleshooting & FAQ

Why is the bearing color (Red) important?

The color of a main bearing (e.g., red, blue, green) indicates its precise thickness to compensate for minor manufacturing variations in the crankshaft and engine block. You must replace a bearing with one of the same color to ensure correct oil clearance and prevent engine damage. Always consult your service manual to confirm the correct color code for your specific engine.

Is this a complete bearing or a single half?

This product is a single half bearing. A complete main bearing assembly requires two halves. Please check how many you need for your repair before ordering.

How do I know if my main bearings are failing?

Common signs of a failing main bearing include a deep knocking or rumbling sound from the engine that increases with RPM, low oil pressure readings, and the presence of metallic particles in the engine oil during an oil change.

Can I install this myself?

Replacing main bearings is a complex task that requires specialized tools and a high degree of mechanical expertise. Incorrect installation can lead to catastrophic engine failure. Professional installation is strongly recommended.
