Wrench between 18 and 19mm?

Like the title says, I find myself needing yet another tool.

Last week I changed differential fluid in my Kawasaki Prairie. The rear fill plug didn't seem to have any size wrench or socket fit. 18mm was too small. 19mm was too big. The plug is located in a slight recess area near my trailer hitch, so my only adjustable wrench wouldn't get enough bite on the hex. Eventually I used a 6pt 3/4 which was also loose, but still the closest match.

What are my options? Is there a SAE size that I don't know about? Should I buy a cheap 18mm and open it up? Anyone done that?

23/32" = .71875" pretty close to halfway between - 18.26mm.

19mm= .748"
18mm= .708"

You'll probably only find that size in Snap-On or maybe Williams. Note: 3/4" is actually bigger than 19mm - but due to manufacturing tolerances and the difference in fit between 6pt and 12pt it could easily be the other way around in the real world.

...and do I need to suggest - once you do get it out, replace it with a new one?

Why not a 17mm ? Yes I know most sets do not include a 17 but if you have to go buy something then why not buythe size you need ?

How would a 17mm help him when he's looking for something between 18 and 19?

If I ran into that situation I would just use my 18.5 mm socket....

Yup, I have a 18.5/19.5mm flip socket for damaged Ford lugnuts. So I would use my 18.5mm socket, too :)

Thanks for all of the help.

I guess I'll buy an 18.5mm socket lol

Btw, I got this atv from a family member who had all services done at a Kawasaki dealer. I guess they had the proper socket, as the fill plug isn't damaged in any way.

Or they never touched it, but i think (hope) that's unlikely.

I know autozone carries the 18.5/19.5 flip sockets in store. I use it all the time on the 2pc chrome lugs that are damaged.

18.5?! What the hell, I didnt even know that existed.

i believe it was made for the ever so wonderful chrome capped lug nuts...

often in a flip socket with 19.5 on the other side... 18.5 for when the cap falls off, 19.5 for when the cap is bulged

that **** is why i bought replacement lug nuts for my jeep

That's the first thing I did to my Jeep. I did brakes on a friend's Comanche and learned that. Ended up driving on sockets and snapped several lug nuts off. Previous owner said it only needed brakes bleed but every thing was frozen or leaking.

Same issue with grand cherokee. I learned the hardway my lug wrench didn't fit the ones with the chrome cap off.

After getting new tires had all new lug nuts installed.

Enjoyed the thread. Sometimes you have to laugh at yourself and move on. Mondays ****.

This. I bought one years ago upon the recommendation of this forum.

The stupid "beauty" caps on lugnuts are the problem. Solid lugnuts whenever possible. If you own something with the stupid lugnuts go buy solid lugnuts, you'll thank yourself. But also buy the socket 'cause buying tools is fun.

It was an '09 Ford Focus that drove me to buy the .5 socket(s). Not my vehicle but now it's easier for me to service whatever comes my way.

I go back to something posted earlier. What was Kawasaki doing? It is hard to believe they intentionally made something that only a "rescue" part fits. It just POs the customers when they have trouble changing their oil. I am reading about these lug nut sockets for the first time. Is there a special Kawasaki part number for the drain plug socket?

Wild Guess: The OEM Kawi fill plug was damaged and replaced with a POS Chinese generic plug that is made to typical Communist standards.

Don't buy a new socket. Buy a new plug.


Better yet, buy a new plug AND a new socket.

This is Garagejournal after all....

Better get two of each then. Stuff breaks or gets lost, and when it does 'two is one and one is none'.

Unless you're like me and by the time I need that backup I can't find it anywhere.

So better buy three of each then.
