I forgot to pick up a couple oil drain crush washers for my 111 cu in '17 Roadmaster recently. This being our only dealer around - is approx 40 mi away. Does anyone know if NAPA Auto Parts or some other retail store may carry these washers ?

Should be able to find metric crush washers at any auto parts store. This is the correct size in the pic. But, you can reuse the old crush washers - I’ve reused crush washers w/o issue. Or, if you want to revitalize the old crush washer, heat it until it glows red and dunk in water. It’ll be like new.
Hi JD, if you still have the old copper ones just heat them up till red hot, with a hand held butane torch and they are good to go again as TIGER mentioned. I do that if I have run out.
I'm with you. You are just holding oil from leaking. I have reused the original ones for most of the 61,000 miles I have on my old RM. Guess what, still no leaks. Just don't torque the crap out of them. Dean
Ditto what Dean E says. I've successfully reused washers without doing anything to them. Mind you, I'd prefer to use a new one every time but it's not necessary IMHO.
IMO, 15 Ft/lbs is a lot of pressure for this plug. This is a thin cased aluminum housing that the threads are in. Too many people have stripped this out. To snug the plug up to keep this thing sealed up and do its job about 90 to 95 inch/lbs is plenty to do the job. 15 ft/lbs equals 180 inch/lbs if you are looking for a reference. Just because it is in their manual does not mean there is a problem with this. I deal with tech manuals all the time, tech writers are NOT mechanics. They simply go off of standard charts if engineering did not put something specific in the drawings. This could likely be a shear load standard torque for this thread size. Don't know for sure, that is just my guess but I can tell you from experience I would not put that much torque on this aluminum thread case. Dean
Quenching from red heat doesn't affect the hardness of copper or brass as it does with steel. It's unnecessary to quench it, it just gets it cool enough to handle quickly. It's been standard practice in handloading for generations to anneal brass cartridge case necks so they don't crack by standing them up in a shallow pan of water, heating the necks with a torch until they start to glow, and knocking them over.
I'm still using the original oil drain plug washers that came on the bike from the factory and the machine is now 4 1/2 years old,has traveled over 70,000 miles,and there are NO LEAKS or SEEPAGE!!! The trick is to clean both sides of both washers as well as their mating surfaces on the bottom of the engine block.And then DO NOT over tighten em.I'm not sure if there is a torque spec on em.I tighten em good and snug and then,a tad more.Done!!!
Torque spec on the drain plugs is 15ft/lbs, which by most here is too much. I go to 100in/lb and use actual bubbled crush washers from Napa to be safe - no leaks so far on two oil changes.
I am like Dave, I just wipe off the washer, wipe off the case and bolt seating surface so all are clean and torque it down. I have never changed the crush washer on anything I have ever owned and never have had any leaks.
I've re-used them. And got new ones. At the local hardware store.
