autoluke Posted June 2, 2019 Share Posted June 2, 2019 attempting to remove the crush gaskets on AC plugs, so that I can use them on other 14mm plugs. Seems like they were positioned on the plug before the threading operation, making them impossible to remove. Any suggestions ? Link to comment Share on other sites More sharing options...
JACK M Posted June 2, 2019 Share Posted June 2, 2019 Probably got crushed into that shape. I can usually hold the washer with a pair of pliers and unscrew the spark plug. 2 Link to comment Share on other sites More sharing options...
