What does '0.025mm oversized' mean for these rod bearings?

This means the bearings are slightly larger than the standard size. They are used when the crankshaft journals have been machined undersize (ground down) during a previous rebuild or due to wear. This allows you to restore the correct oil clearance.

What engine codes are these bearings compatible with?

These ACL rod bearings are specifically designed for the B17A1, B18A1, and B18B1 engine codes found in various Acura and Honda models.

Do these bearings come with installation instructions?

While these bearings are designed for a precise fit, it is always recommended to consult your vehicle's official service manual for detailed installation procedures and torque specifications.

About this part

Product Details

This set is 0.025mm oversized, which is important if your crankshaft journals have been ground down during a previous rebuild or due to wear. Using an oversized bearing like this helps restore the correct oil clearance between the rod and the crankshaft. Proper oil clearance is essential for lubricating the bearing surfaces, reducing friction, and preventing premature engine failure. ACL is known for making well-built engine components, and these bearings are no exception, offering a solid option for performance builds or engine overhauls.

When installing these bearings, always refer to your vehicle's service manual for the correct torque specifications and procedures. Ensuring the crankshaft journals are clean and smooth before installation will also help these bearings perform as intended.
