Question 1

What does 'standard size' mean?

Accepted Answer

Standard size means these bearings match the original factory bearing dimensions. If your crankshaft has been machined undersize, you'll need to use undersized bearings instead.

Question 2

How often should I replace my main bearings?

Accepted Answer

Main bearing replacement intervals depend on engine use and maintenance. Inspect your bearings during any major engine work, and replace them if you see signs of wear or damage. Always follow the manufacturer's recommendations.

Question 3

Do these bearings come with installation instructions or torque specifications?

Accepted Answer

This ACL main bearing set does not include installation instructions or torque specifications. Refer to the BMW factory service manual for the correct procedure and torque values.
