Where in the U.S. can I get oil drain plug crush rings for my 2018 Speedmaster? Is there a part number or a list with crush rings for other vehicles that are compatible?
I am not sure why you would want a "crush ring" almost all Triumphs use a solid washer with no issues. If you really want a crush ring pop along to your nearest motor factor accessory shop, these usually stock packs of multiple sizes and are very reasonably priced.
Hmmm...Pretty sure the service manual called for a crush ring and I've used them on my bikes in the past, but if a solid washer will do, I'll go with that.
Don't know your size & part number, but find out what size is your drain plug (M14? M12?...etc) then go to your nearest auto part dealer, find a copper crush washer for that size. Depends on the size, sometimes you can literally get 50 for 10 bucks.
Just didn't feel like going shopping with drain plug in hand in the middle of an oil change. Thought someone might know off hand. No worries. There are three auto parts stores within ten minutes of El Rancho Fork Lock. I'll just bring the plug and find a matching crush ring. Thanks all.
Is it just a copper washer? Can you reuse what you have by annealing it (heating red hot then letting it cool)?
The OEM washer looks like a plain (not crush) aluminium washer and the size in mm is on the packet, shown in the picture below I just took of one I have. That is 3mm thick, 23mm diameter, with a 14.4mm hole (9/16 inch). Edit: The size is also given on online parts ordering sites, e.g. at Fowlers. Just Google the part number. Note, Fowlers (where I buy parts) doesn't show the Speedmaster parts diagram, but I use this site for reference... https://www.bike-parts-triumph.com/...neville/Speedmaster/bonneville-speedmaster/15
Thought I was being clever and tried annealing a silver coloured sump washer. Oops, I melted it. Lesson learned.
I used to reuse those washers and never had a problem. They say to replace them each time because "they" don't know what condition they're in. You can safely get many uses out of them if you don't overtighten them. I've only seen them leak when not tight enough.
The sealing washer on my 2012 ZZR is aluminium, (aloominum on the USA spec bikes ) and is the original from new. Never changed it or had to. As Tom Swift has said, they last almost indefinitely if not abused.
