Using the Bochum Plug for draining engine oil Today I changed the engine oil without use of any tools for the drain plug. I have the Bochum plug installed.
The original 24 mm plug is very difficult to remove. I have only unscrewed the plug twice with a 3/4 inch breaker bar. Since then I have used a vacuum pump to drain oil. No more with this plug.
The plug is used instead of the original oil drain screw. To drain the oil, the cap is removed and a hose nozzle screwed on releasing a spring loaded stop valve.
The valve of the plug opens and the engine oil can be collected in a controlled manner.
These plugs are commonly used on construction machines.
