What does the 0.5mm undersize mean for my engine?

The 0.5mm undersize specification means these bearings are intended for use when the crankshaft journals have been machined down by 0.5mm. This is typically done to correct for wear or damage on the original crankshaft, ensuring proper fit and oil clearance with the new bearings.

What is the construction of these main bearings?

These main bearings are constructed with a bimetal design, utilizing an aluminum base. This type of construction is common for engine bearings and is chosen for its ability to handle load and wear effectively within the engine environment.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required to replace the set in your Datsun L18 engine. You receive the complete set needed for the job.
