What does the 0.75mm undersize mean for these bearings?

The 0.75mm undersize indicates that these bearings are designed for a crankshaft that has been machined down by 0.75mm. This is typically done to correct for wear or damage on the original crankshaft journals.

What is the CP-2 micro-babbitt overlay?

The CP-2 overlay is a special coating King Engine Bearings uses on their bearings. It's designed to embed small particles of debris, which helps protect the crankshaft journals from scoring and damage during operation.

What is the primary function of main bearings?

Main bearings are crucial for engine longevity. They support the crankshaft within the engine block, allowing it to spin freely while withstanding the significant forces generated during combustion and power delivery.

About this part

Product Details

This is a main bearing set from King Engine Bearings, specifically sized 0.75mm undersize for the Isuzu 4HK1 engine. Main bearings are critical components that sit between the crankshaft and the engine block, supporting the crankshaft and allowing it to rotate smoothly while handling immense loads.

King uses their advanced CP-2 micro-babbitt overlay on these bearings. This overlay is known for its ability to embed debris, which helps prevent damage to the crankshaft journals. The 0.75mm undersize means these bearings are intended for a crankshaft that has been machined down by 0.75mm to correct for wear or damage. Proper installation, including ensuring the crankshaft journals are clean and within the specified tolerance for the undersize, is key to their performance.
