King Engine Bearings MB 540AM0.75 OE-Replacement Main Bearing Set for Isuzu G130 G161 G200 +0.75mm

The King Engine Bearings MB 540AM0.75 is an OE-replacement crankshaft main bearing set designed for Isuzu G130, G161, and G200 engines. This set is supplied in a +0.75mm oversize, making it the correct choice when crankshaft journals have been reground to that specification during an engine rebuild.

This bearing set is part of King's AM Series — the standard aluminum-based bi-metal bearing line. The AM Series uses King's softest bi-metal material, equivalent to SAE-783, making it ideally suited for passenger car engines operating under low to medium loads. The material is completely lead-free, making it environmentally responsible and safe for builders and technicians.

Key Features:

• AM Series bi-metal construction — Standard aluminum-based material (SAE-783 equivalent) for low to medium load engines
• +0.75mm oversize — Engineered for crankshafts that have been reground 0.75mm undersize
• 5-pair set — Includes all main bearing pairs required for a complete engine rebuild
• Lead-free formulation — Environmentally safe composite material
• Bull's Eye Tolerance™ Technology — Precision manufacturing using highly accurate machining, overplating, and computerized wall thickness monitoring
• Superior embeddability — Allows macro-particles to embed into the bearing surface, reducing scratching of crank journals and protecting the overlay
• OE-replacement grade, suitable for street and marine engine rebuilding applications
