Front Wheel Axle / Rear Wheel Axle Hex Nut Size.

MFP · Sep 22, 2020

I have quite thoroughly checked through my Yammy S10 service
manual for the size of the hex nut opening on the front & rear wheel axles with no luck (17 or 19MM ?).
I prefer to buy a separate hex nut socket not one of those 4-n-1 hex axle tools.
Thanks,
MFP

The spark plug tool in the OE tool kit is supposed to work. And, apparently some do. Mine does not. I thought it was a 19mm. I bought a multi size socket. I'm not a fan of multi-tools either, but it worked fine. This is the one I got from Amazon.

Front and rear axle both use 19mm hex socket.

19mm

And do yourself a favor: never use the pinch bolt to hold the axle when torquing to spec. Always use that 19mm hex.

Motion pro makes a lightweight one if you want to get one for the road, but i dig this one i got on amazon:

Titan 15619 1/2-Inch Drive x 19mm... https://www.amazon.com/dp/B004W7F6S8?ref=ppx_pop_mob_ap_share

Got it, Thanks.
Titan makes pretty decent tools, I have a decent amount of their sockets and such....

I think with a little grinding and filing it would work. That said I carry a hardened 19mm hex.

I'd still find a way to screw it up. Mr. Murphy is a constant visitor.

19mm hex or 3/4" which is identical whithin a few thousandths.

I use my spark plug socket. Just put the extension in the opposite way. The hex portion is 3/4.

It's kind of related, the big nut on the other end of the rear axle is 27mm.

That's exactly what I do.
I know the thread is a few years old but It need to be seen again.
