What does the +0.50mm sizing mean for this bearing set?

The +0.50mm sizing indicates that these bearings are slightly larger than standard size. They are intended for use when the engine's crankshaft journals have been machined down by 0.50mm during a rebuild to correct wear or out-of-round conditions.

What is the construction of these main bearings?

These main bearings feature a bimetal construction, utilizing an aluminum base. This design helps with heat dissipation and provides a durable surface for the crankshaft to rotate against.

Are these bearings a direct replacement for all Datsun L28 engines?

This set is specifically sized at +0.50mm, making it an option for Datsun L28 engines that have had their crankshaft journals machined to this undersize. It is an optional part for the MB 768AM (flange STD) if you require the +0.50mm sizing.
