This oil drain valve controls the flow of engine oil during service intervals. It is installed in the engine oil pan or oil circuit, where it provides a controlled opening for draining used oil without requiring the removal of the pan. The valve is operated manually or by a tool; when opened, it allows the oil to exit under gravity. A worn or leaking valve can cause oil seepage, leading to low oil level and potential engine damage. This original AGCO part is manufactured to the same internal bore and sealing geometry as the original assembly, so it seats correctly in the housing without requiring additional gaskets or adapters. On reinstallation, tighten the valve to the specified torque to prevent leaks.
