1957 Douglas Dragonfly oil drain plug.
« on: 22 Jul 2020 at 14:56 »
Hello. Would anyone happen to have the dimensions for the engine oil drain plug for a 1957 Dragonfly, please? We are in need of one and right now the website's parts service is not in service. I am hoping to source an alternative.

Thanks,

Andy

Andy,
          The drain plug in the Dragonfly (and Mark series engines) is a standard 1/4"BSP brass plug - here in the UK, they are available from plumber's merchants. (Note: the thread is actually .518" dia x 19 tpi.)

  Hope this helps,
                            Regards,
                                          Eddie.
