Question 1

What does '+1.00' mean in the product description?

Accepted Answer

The '+1.00' indicates that these main bearings are 1.00mm oversized. This is for engine blocks that have been machined, which increases the crankshaft bore size. Using oversized bearings in a standard bore will cause serious engine damage.

Question 2

How do I know if I need oversized bearings?

Accepted Answer

During an engine rebuild, the machine shop will measure the crankshaft bore. If the bore is larger than the standard specification, they will recommend using oversized bearings to compensate for the increased clearance. Always follow the machine shop's recommendations.

Question 3

Are these bearings sold as a complete set?

Accepted Answer

Yes, this ACL main bearing set includes all the bearings needed for a complete engine rebuild. You'll get enough bearings to do the job right, assuming you have a stock configuration.
