It supports CAT models across the 3176, 3196, 3200, 3208, 3300, 3400, 3406, 3500, 3508, and 3512 series, as well as C9, C10, C12, C13, C15, and C16 engines. It also pairs with Mack E-7 and ETEC configurations, making it suitable for both EUI and MUI systems. This versatility makes it a practical addition to shop inventories and field service kits.\u003c\/p\u003e\n\u003ch3\u003eDurable, precise construction\u003c\/h3\u003e\n\u003cp\u003eCrafted from high-grade 42CrMo steel, this barring socket combines durability with reliable tolerances. It features an eight-spline engagement, a 1.725\" diameter (43.815 mm), and a 1\/2\" drive. The precise dimensions help ensure a tight, consistent fit on compatible flywheels, supporting smoother rotation during service tasks.\u003c\/p\u003e\n\u003ch3\u003eDirect OEM replacement\u003c\/h3\u003e\n\u003cp\u003eDesigned as a cost-effective alternative, it directly replaces OEM numbers J-38587-A, Caterpillar 9S9082, 0508477, and OTC6749.
