What does the +0.75mm sizing mean for these main bearings?

The +0.75mm sizing indicates that these bearings are larger than standard size by 0.75 millimeters. This is typically used when the crankshaft journals have been machined undersize to correct for wear or damage, and these bearings are needed to restore the proper clearance.

What is the bimetal construction and why is it important?

Bimetal construction uses two layers of different metals, in this case an aluminum base. This design offers good load-carrying capacity and conformability, allowing the bearing to adapt to the crankshaft and absorb shocks effectively, which is crucial for engine longevity.

Does this main bearing set come with all the necessary hardware for installation?

This product is a set of main bearings only. It does not typically include installation hardware such as new bolts or seals, which should be sourced separately if needed.

About this part

Product Details

Built with an aluminum-based bimetal construction, this main bearing set from King Engine Bearings is specifically sized at +0.75mm for Nissan E15, E16, E13, and E15ET engines. These bearings are a crucial component for the crankshaft's smooth rotation within the engine block, helping to reduce friction and wear on critical rotating assembly parts.

When rebuilding or repairing an engine, especially one of these older Nissan models, ensuring the correct bearing clearance is key. This set, being 0.75mm larger than standard, is intended for applications where the crankshaft journals have been machined down to accommodate this size. The bimetal design offers good conformability and embeddability, which are important for handling the loads and temperatures found in an engine's main bearing saddles.

This set is designed as a direct replacement for the main bearings in your Nissan 310, Pulsar NX, Pulsar, or Sentra from the specified years. Always refer to your vehicle's service manual for proper installation procedures and torque specifications.
