CATERPILLAR-3400-CONROD-BEARING-0635

7E0558 is a connecting rod bearing at the 0.635mm undersize step for Caterpillar's 3400 series engines, an unusual increment reflecting a metric conversion of an originally inch-based undersize on this engine range. Confirming this exact figure against your crank's regrind certificate matters more than usual here given how specific the number is. Orange.net.za dispatches this part fast, South Africa-wide.
