M16 OVB 6023 Drain Plug (ZM-120U Travel Differential)

M16 OVB 6023 Drain Plug (ZM-120U Travel Differential)

The M16 OVB 6023 drain plug is a threaded sealing and closure element for the sealed drum of the ZM120 06.100.000-05 differential, designed to provide level control, fluid filling, and periodic draining of lubricant. It is utilized on our ZM-120U series self-propelled grain throwers, as well as during the modernization and retrofitting of running systems on other grain thrower series when transitioning to a gearless drive layout with an independent gearmotor.

The component threads directly into the threaded opening of the ZM120 06.100.001 oil drum housing. Reliable sealing of this connection is especially critical because the differential housing operates as a closed oil bath. During grain thrower movement, the lubricant inside the drum constantly washes over the bevel side gears, half-axle gears, and cermet bushings, while any plug leakage leads to oil loss and rapid component wear.

Design Features and Advantages of the M16 Differential Drain Plug

The steel execution with a zinc-plated coating protects the threads from corrosion and seizure. The use of high-strength structural steel prevents hex rounding during tightening or loosening with an Allen key or box wrench. Galvanic zinc plating protects the threaded connection from oxidation and corrosion during prolonged outdoor operation, preventing the component from seizing into the drum housing.

The precisely cut M16 metric thread ensures a tight seal fit. High-quality turning of the M16 thread turns guarantees plug installation without play or misalignment. Due to the flat clamping plane of the head, uniform compression of the sealing washer is achieved, blocking oil leakage even under elevated pressure and temperature inside the drum during intensive operation.

This plug also provides convenient access for routine maintenance. Its location on the outer diameter of the drum allows for quick oil level checks or complete replacement without the need to dismantle and disassemble the travel axle. To drain waste oil, it is sufficient to rotate the drum until the plug points downward, and for filling fresh oil, position the opening at the top or side.
