Oil change Q: Crush washer size?

JDToronto · Nov 8, 2016

Hey all,

I live in the great white north of Canada and that means having to winterize and store my bike soon. Part of that process includes an oil change, which I'll be doing myself. Don't foresee any issues, I've done oil changes before, but the manual calls for a sealing washer replacement for the sump plug.

Anyone know what size it is? I can obviously just measure when I do it, but I like having all the necessary parts/etc. to do the deed in one go without having to run to the hardware store mid-way through the process.

Cheers.

Edit: Should mention I have a Street Twin

I have done 4 oil changes this season and I reused the original washer each time without any leaks. Make sure the flat side of the washer faces the oil pan and use a torque wrench.

Aluminium, dimensions: Internal diameter 14.4mm, Outside diameter 23mm, thickness 3mm.

Same item as used on all Bonnies since 2001 and lots of other Triumphs, part number T3558989.

And thanks to everyone else as well for the replies.

It's not a crush washer. It's a fairly robust thick and hard aluminium washer which shows no signs of distress when torqued to the correct value.

Well, it's aluminum and will crush a little if squeezed too much but no harm done. Many of my last few, well all of them had an aluminum drain plug washer. Some have formed a slight ridge. They can be reused without leaking, I take the used washer and run it over a flat file to smooth it out. If it makes you feel better get a new one.
