Street Twin Oil Drain Plug Alum Washer

Hello - Can anyone advise what is the specs (OD, ID & thickness) for the alum crush washer used on a 2017 Street Twin oil drain plug? Thanks

 

OD 23 mm
ID 15 mm
Thickness 3 mm

 

Great, thanks for the info

 

In checking a few local suppliers, that's such a non standard size that no one has. Some things are never that simple..

 

There’s nothing special about them. I think you will find they are M14 and actually measure about 14.5mm. Thickness is not critical to function nor is material. Copper is equally good in this role. Your our local auto factor will have plenty and cheap.

 

Or put a tap washer on it if you can’t be arsed
