What does 'Housing Bore +.010' mean for this bearing set?

This means the main bearing housing in your engine block has been machined to be 0.010 inches larger than the original factory size. This bearing set is specifically sized to fit that modified housing bore.

What is trimetal construction?

Trimetal bearings use multiple layers of different metal alloys. This construction helps them handle high loads and temperatures, offering good durability in demanding engine applications.

Is this bearing set a direct replacement for all Isuzu 4HK1-TCN engines?

No, this set is specifically for 4HK1-TCN engines where the main bearing housing has been machined to a +.010 inch oversized bore. It is an optional replacement for MB5743CP, which also fits a +.010 housing bore.

About this part

Product Details

King Engine Bearings is well-known for making solid engine components. This main bearing set is built for the Isuzu 4HK1-TCN engine, specifically for builds where the housing bore has been machined to be +.010 inches larger than stock. These are a trimetal bearing, which means they have multiple layers of different metals to handle the stresses of engine operation.

If you're rebuilding the bottom end of your Isuzu 4HK1-TCN and have already had the main housing bored out to +.010, this set is designed to fit that specific dimension. The 0.50 oversized sizing accounts for that machining, ensuring a proper fit and function for the crankshaft within the block. This is an optional replacement for part number MB5743CP, which also fits a +.010 housing bore.
