O Ring ‘Green in colour’

techi · Oct 9, 2021

Hi All,
Hopefully someone can help, please see attached pic. There’s a green O ring behind this cover and it has presented an oil leak, I’ve replaced with same size black O ring which stops oil leak for a month maybe two and then leaks again. Would somebody have the part number for the correct O ring. I’m of course assuming the issue is the O ring and open to your thoughts, maybe other have experienced same leak.

Just change it to your bike model

@skudd thanks for that, I’ve had a look but it doesn’t break it down, so can’t identify from there. Handy site I definitely book mark.

Is your bike a twin cam ?? or WC ?

The O ring below should fit twin cam but maybe not WC

My bike is a 2005 R1200GS and I have just replaced this O ring due to an oil leak. The part number I used was 11147665328. You are right it is green in colour.

When servicing dive equipment the green o rings are for nitrox, ie oxygen safe as opposed to the black ones which are not at higher percentages.

No idea about your bike, but if it should be green, personally I’d fit the green. I may have some spare if you get stuck.

O-ring 11 14 7 665 328 48X3
