What does +0.75mm mean for these bearings?

The +0.75mm designation indicates that these bearings are slightly larger than standard size. They are intended for use when the crankshaft journals have been machined down by 0.75mm to remove wear or damage.

What is bimetal construction?

Bimetal bearings, like these from King, use an aluminum alloy as the primary bearing material. This construction is known for its good load-carrying capacity and compatibility with various oil types.

What else might I need for this installation?

When replacing main bearings, it's standard practice to also replace the connecting rod bearings. You'll also need assembly lube to coat the bearings before installation and new main bearing cap bolts or studs.

About this part

Product Details

If you're rebuilding the bottom end of your 1979-1985 Mazda GLC with an E3 or E5 engine, a fresh set of main bearings is crucial. These bearings sit between your crankshaft and the engine block, supporting the rotating assembly and ensuring smooth operation. This set from King Engine Bearings is specifically made for those engines, helping you get your rebuild done right.

King uses a bimetal construction, which means they have an aluminum base. This design is well-suited for the demands of an engine, offering good durability and performance. This particular set is sized at +0.75mm, which is important if you're dealing with a crankshaft that has been machined undersize during a previous rebuild or to clean up wear.
