CATERPILLAR-3176-C10-CONROD-BEARING-051

128-0390 is a 0.51mm undersize connecting rod bearing for Caterpillar's 3176 and C10 engines. This engine range uses an unusual undersize increment compared to the standard 025/050/075 pattern elsewhere in Cat's catalogue, reflecting a metric conversion of an originally inch-based undersize spec — worth being precise about the exact reference rather than assuming it lines up with the more common 050 step. Orange.net.za ships this part fast, South Africa-wide.
