What does the 0.75mm size mean for these bearings?

The 0.75mm designation indicates that these bearings are 0.75mm undersize compared to a standard main bearing. This means they are intended for use when the engine's crankshaft has been machined down by 0.75mm to correct wear or damage.

What is bimetal construction?

Bimetal bearings, like these from King Engine Bearings, are made with a steel backing for strength and an aluminum-based overlay. This combination offers good wear resistance and compatibility with the crankshaft, making them suitable for engine applications.

Do I need to purchase anything else with these main bearings?

When rebuilding an engine, it's essential to also replace the engine oil and oil filter. You may also need main bearing cap bolts and potentially main bearing alignment dowels, depending on the specific engine and rebuild procedure.

About this part

Product Details

This is a King Engine Bearings Main Bearing Set, specifically designed for the 5MGE, 7MGE, and 7MGTE engines found in select Toyota models like the Cressida, Celica, and Supra from the early 80s through the early 90s. These bearings are a critical part of your engine's rotating assembly, supporting the crankshaft and ensuring it spins smoothly within the engine block. This particular set is sized 0.75mm (or +0.030 inches) undersize, which is important if your crankshaft has been machined to this size during a rebuild.

King Engine Bearings uses a bimetal construction for these main bearings, meaning they have an aluminum-based overlay. This type of material is well-known for its good compatibility with crankshafts and its ability to handle the loads and temperatures inside an engine. When you're rebuilding an engine, getting the right size and type of bearings is crucial for proper oil clearance and long-term durability. This set is a solid option for anyone working on these specific Toyota engines.
