CATERPILLAR-3064-3066-CONROD-BEARING-025

5I7794 is the 0.25mm undersize step for Caterpillar's 3064 and 3066 connecting rod bearing. Because bearing clearance directly governs oil film thickness at the journal, even this smallest undersize step matters for correct oil pressure — it is not a case of close enough being acceptable between adjacent size steps.
