Replacement sump plug washer for most 750/101/102/106/105 series twin-cam engines. We supply copper or aluminium depending on availability from our suppliers - both work equally well.
We recommend you replace any crush washer once it has been used more than once, to reduce the chance of leaks and breakages.
22mm internal measurement.
Also used on the gearbox and diff filler plugs on many models. Check the internal measurement!
