What is the size of these main bearings?

This is a 0.50mm undersize main bearing set. This means it is intended for use when the crankshaft has been machined down by 0.50mm.

What does 'bimetal' construction mean for these bearings?

Bimetal construction typically refers to a bearing with a steel backing and a bearing material overlay, often aluminum-based. This design offers good strength and conformability for supporting the crankshaft.

Do I need to replace the crankshaft when using these bearings?

These bearings are 0.50mm undersize, indicating they are meant for a crankshaft that has been machined to that specific size. If your crankshaft is still at standard size, you would need a standard-sized bearing set.

Mazda GLC 1979-1985

Product Details

If you're rebuilding the engine in your 1979-1985 Mazda GLC with an E3 or E5 engine, a fresh set of main bearings is a critical part of the job. These bearings sit between the crankshaft and the engine block, supporting the rotating assembly and ensuring smooth operation. This set from King Engine Bearings is specifically made to fit your GLC, helping to restore proper oil clearance and support.

These main bearings are constructed with a bimetal design, meaning they have an aluminum base. This construction is well-suited for the demands of an engine rebuild, providing reliable support for the crankshaft. This particular set is 0.50mm undersize, which is important to know if you're machining your crankshaft to match. Using the correct size bearings is key to achieving the proper oil clearance, which is vital for engine longevity and performance.
