Same as a 14mm spark plug washer.

My solution.... Found a fiber type washer in the true value (chain small hardware shop) that sealed with little torque. Had been fine for months.

I see the photo from the original post, I think you guys are saying that there is an old crush washer on his that needed to be pried off? Can you guys take a look at mine and let me know for sure, is that ring an old over-crushed washer or part of the drain plug? Thanks!

Old washer, but if it ain't leaking "I" wouldn't fool with it...Just my opinion.

I'd replace that crush washer. They are single-use. I've had to get aggressive with one like in the pics in post. #19, using a cut-off wheel in a dremel. Careful not to nick the threads. Once the washer started to move, I didn't have to cut all the way thru, they it came off easily. NOT recommending this technique, but it worked for me.

Thanks, guys, I will carefully remove it.

A sharp pick can sometimes get under there as well

**bwringer** · 04-19-2022, 05:53 PM

Yup, old washer. And I use a knife blade I don't care about. Tap it into place gently to open up a little prying space.

Earls 178109ERL Dowty Seal, 9/16 Inch Diameter, Fits -6 AN Fitting

http://www.speedwaymotors.com/Earls-178109ERL-Dowty-Seal-9-16-Inch-Diameter-Fits-6-AN-Fitting,142385.html?sku=425178109ERL&utm_medium=CSEGoogle&utm_source=CSE&utm_campaign=CSEGOOGLE&gclid=EAIaIQobChMI_pGs0eal1gIVCI1pCh36CwCBEAQYASABEgJWo_D_BwE

Standard practice in the U.S.A. is to use crush washers, O rings and/or Stat-O-Seals to seal ports and banjo fittings. English practice is to use Dowty Seals . Dowty seals are similar in concept to our Stat-O-Seals, but are considerably smaller in diameter (and thicker in cross section). Since many of our road racing and Indy cars and their mechanics are of English origin, Earl's offers a complete range of Dowty Seals. English Practice Considerably Smaller Diameter Thicker In Cross-Section Complete Range Offered

I torque to about 17-20lb (as advised by those "in the know" with the KLR who torque at 17lb - also AL threads).

I'll second that. Dowty seal washers are great for the drain plug. I just pulled the plug the other day and the darn thing was little more than hand tight. In spite of the nearly loose plug, not a drop of oil leaked out. I'll atribute that to the dowty seal.

OK, I got the old washer off using a vise, utility blade, hammer, small cold chisel, side cutters, and channel locks in that order. No damage to the drain plug. Probably not worth the time other than thinking that it was the original 1979 plug. Don't tell me if it wasn't.
