Oil drain copper washer
 

I know that you are supposed to replace the copper washer on the oil drain bolt each time you change the oil but who does?

do you?

if so, where can I source replacements - do you have to buy the original ducati ones?

Erm...NO, hands up - I dont replace it each time.

For a quick replacement - try a plumbing supplier - I had to file it out a little, but for a few pence, it worked a treat.

For what the originals cost, is it really worth not changing it? I've seen a couple leak. Not many but if there's £40 worth of oil splashing around in there, do you really want to drop it again?
Get the 2 washers and filter at the same time and you're sorted.

Oh Nooooo - I feel so bad now, I do use a torque wrench when fitting it - does that keep me away from the burning hell of the Ducati Bottchers ;)

I think I paid something like 20p for the washers, at that price why not buy a supply so you dont have to take a trip to a ducati dealer next time you change the oil

I never knew you were meant to replace the washers. On the monster I just sold I did 3 oil changes and never changed them. Not a drop leaked from that.

At that price though I may start doing it just for the sake of it.

I replace all of the drain washers (gauze plug and the drain plug) evertime I change the oil. I order my filters from italia and they always chuck in the washers for me.

Aren't they aluminium?

They are ony my 748; I really can't remember about the 750SS. But yes, the only cost pence.

the ones I got from Ducati Aylesbury looked like they were aluminium

I have to confess that in all the years I've done my own oil changes (since 1976) I have only changed the washer once - and that was when there was a small leak. I've never found it a problem, but I was recently berated by an engineer for not changing the washer. I figure if it don;t leak it must be doing it's job.
With regard to copper vs ally - provided it's soft enough to compress and seal I don't suppose it matters.
