I have been trying to locate some cylinder head/crankcase nuts for a 1972 EXT. Part #3000-097. These nuts are 8mm 1.25 pitch heavy concave bottom nuts commonly used on a lot of Kawasaki motors around 72-74.
I have checked most of the NOS suppliers such as Jerry'sNOSCatparts, and every other NOS part supplier I could find. No luck. I've also tried local suppliers such as fastenall, and many other specialty fastner companies And still no luck.
If anyone knows of a source for these nuts I would appreciate a reply! Thank you
I'm REALLY surprised you cant find them locally, but try McMaster Carr, if they don't have it I will need to reconsider my lifeRockerdude they don't tell you shipping cost until it ships, but it should be around 5$ for shipping on these, it always seems to be reasonable
I have had several people tell me to try McMaster and I found a heavy nut, but no flat/concave on the bottom. McMaster-Carr (link)
Same 13mm width and 6.5 mm depth as OEM, but both sides are the same with beveled edges. The OEM nut has one flat/slightly concave side and one beveled edge side.
I realize it is an EXT, my dad has a couple so I understand the wanting it bone stock, but is it really worth it? get ones with the rounded top and bottom and you'll never notice the bottom isn't rounded.
also, are you sure that is the way its supposed to be? head bolts tend to get chewed up by the lock washers...
I can check with my dad/his 72's to see if they have this odd nut...
Yeah I hear you about going with the nut rounded on either side- I was wanting to stick with the original part, and I figured there was a reason for the flat side of the nut.
I'm sure that the nut is supposed to be flat on one side. I took some brand new nuts off the EXT triple crankcase, (see picture above), and compared it with some nuts I took off a 73 Panther motor and they both had one beveled side and one flat side.
