King Engine Bearings Isuzu G130/G161/G200 (Size +0.50mm) Main Bearing Set

This is a King Engine Bearings Main Bearing Set, part number MB540AM0.5. Inside this box, you'll find the main bearings needed to rebuild the bottom end of your Isuzu G130, G161, or G200 engine. These bearings are sized +0.50mm, meaning they are intended for use when the crankshaft journals have been machined down by 0.50mm during a rebuild. They feature a bimetal construction with an aluminum base, which is a common and reliable material for main bearings.

Main bearings are critical for keeping your crankshaft properly supported and lubricated. They sit between the crankshaft and the engine block, creating a precise oil clearance that allows the crank to spin freely while maintaining oil pressure. When rebuilding an engine, especially if there's wear on the crankshaft journals, using the correct size bearings like these +0.50mm ones is essential for restoring proper oil clearance and ensuring the longevity of your engine. This set fits a range of vehicles, including Chevrolet LUV pickups and Isuzu Pickups from the 1970s and 1980s.
