King Engine Bearings MB 416AM1.5 AM-Series Main Bearing Set +1.5mm Oversize

The King Engine Bearings MB 416AM1.5 is a complete crankshaft main bearing set engineered for the Daihatsu Charade engine family. This set is supplied in a +1.5mm oversize housing dimension, designed for use during engine rebuilds where the crankshaft journals have been reground to restore proper bearing clearances.

These bearings are built using King's proven AM-Series (Alecular Material) construction — a bi-metal design featuring an exclusive aluminum, tin, and copper-plus alloy bonded to a high-strength steel backing. The Alecular alloy delivers an exceptional combination of load capacity, embeddability, and conformability, making it well-suited for street and marine gasoline applications.

Key Features:

• AM-Series Alecular Material: Proprietary aluminum-tin-copper alloy on high-strength steel for superior durability and wear resistance
• +1.5mm Oversize Housing: Precision-sized for engines requiring oversize bearing bores after block machining
• High Macro-Particle Embeddability: Captures and embeds contaminant particles to protect crankshaft journals from scoring
• High Conformability: Adapts to minor surface irregularities for optimum oil film distribution
• Lead-Free Composition: Environmentally responsible and RoHS-compliant formulation
• Precision Tolerance Control: Manufactured to tight dimensional tolerances for consistent oil clearance
• Broached/Finished Bore Surface: Optimized surface finish for immediate oil film retention at startup

King Engine Bearings has been a global specialist in engine bearing manufacturing since 1960, producing bearings exclusively — a focus that results in tightly controlled quality across every set. The MB 416AM1.5 is the correct choice for Daihatsu Charade engine rebuilds requiring a standard +1.5mm oversize main bearing set.
