Question 1

What does '0.025mm oversized' mean?

Accepted Answer

When an engine is rebuilt, the main bearing surfaces on the engine block and crankshaft are often machined. This removes material, which increases the clearance between the crankshaft and the block. An oversized bearing compensates for this extra clearance, ensuring proper oil pressure and bearing function.

Question 2

Are these bearings compatible with other engine modifications?

Accepted Answer

These bearings are designed to be compatible with the stock KA24DE crankshaft and engine block, provided the block has been machined to accept 0.025mm oversized bearings. Other modifications, such as aftermarket connecting rods or pistons, should not affect bearing compatibility as long as the crankshaft and block dimensions remain within specification after machining.

Question 3

What else should I replace when installing new main bearings?

Accepted Answer

When replacing main bearings, it's always a good idea to inspect and/or replace the connecting rod bearings at the same time. Refer to the manufacturer's installation instructions for proper bearing installation procedures and torque specifications.
