Gearbox drain plug thread
« on: 09 May 2019 at 22:18 »
Hi All
Can someone tell me the thread size of the gearbox drain plug on my 80+?
The diameter is 3/8, I believe, but the thread is too fine for BSF.
Any thoughts?
Many thanks
Dave

Yes Dave,
                 The thread is 1/8"BSP - that is .383"dia x 28 tpi. If you need a new plug, they are available from plumbers merchants, but need the flange turned down so that it just clears the bottom of the gearbox side cover.
  Hope this helps,
                            Regards,
                                           Eddie.

Great, Eddie
That's what I suspected and I'm glad that you have confirmed it.
Many thanks
Dave
