Stripped thread final drive drain plug

[vRSG60]

Yes I'm an idiot, I don't need telling.

During the course of servicing my bike today I managed to put the filler plug back into the drain hole by mistake, they are the same diameter but a differant pitch, bad practice I know.

The consequnce of which is that the drain plug will not tighten up in the drain hole.

I've removed the final drive & I'll take it into our machine shop tomorrow but I don't think a helicoil can be fitted due to the sealing medium being an O-Ring and not a crush washer, the very reason I made the mistake in the first place.
So - has anyone come across this before and come up with a solution?

Not made the mistake but Id use a wurth time sert to repair the threads.

The filler is M12x1.5 the drain is M12x1

I cant say for deffo, as you didnt say what bike , year or month of manufacture

if you provide those we may be onto a winner

can you not whack some PTFE tape round the drain to see if that will work?

Crazy they use a different pitch for the same thread diameter

If you could skip dive around the back of your local motorrad dealers workshop you could probably find half a dozen perfectly good FD still with rusty driveshafts attached, a quick whack with a hammer and some plus gas and jobs a good’un.

To draw a line under this.
Luckily the threads are fine when a tap is run down them.

Drive casting blown out and some oil put in a swilled around before draining.
