Another issue - one of my nuts is mis-shaped! ;-) (Cylinder stud problems)

[Argee]

The front left cylinder stud securing nut (closest to the cam-chain) on my GS1100GL has been deformed. A 14mm socket will not grip it, and a 13mm socket is too small.

Do I:

attempt to file the faces of the nut so that I can get the 13mm socket onto it? Or,

use a punch to tap it around to undo it? Or,

try to cut the nut off with a dremmel cutting wheel?

I did wonder about heating it first, but I'm worried that the cylinder head alloy might melt...


Obviously I'll probably need to replace the nut in question, so does anyone know the most cost-effective way to find a replacement? Does it have to be specifically for a GS1100, or would any GS Stud nut do? Does it need to be a Suzuki one - are there generic ones available?

As ever, all advice very gratefully received!

OMG!

You're deformed with that thread title! Lol

I thought it might get a laugh!

If the nut is deformed it may destroy the stud when you spin it off. If possible I'd cut it off.

Yeah and one of mine is larger than the other two! LOL

Use a nut extractor. These are special sockets with spiral teeth inside made for addressing this exact situation.

You can order new nuts cheap from your favorite source for Suzuki parts. Or post in "parts wanted" and someone will be able to dig up a few in good shape to send you.

The biggest issue with using hardware store nuts is that they'll be too big -- most US and Euro 10mm nuts use a 17mm hex with 1.5mm thread pitch (even if you get fine thread, they're still usually 17mm hex). Plus, the "acorn" style used at the corners is specific to the GS. 10mm thread nuts on Japanese machinery use 1.25mm thread pitch and 14mm hex.

All in all, it'll be a lot easier to order new nuts from Suzuki or get good used ones.

I order the Irwin extractor sets for my guys at work. Easy to use. use some kroil or pb blaster to make it easier to get off

Did you try a 6 point socket?

 

[Big T]

You might also try to see if a 9/16", or 5/8" will fit on it

 

[uk gs nut]

5/8 is too big 9/16 may work, as said use a 6 sided socket. I will have a few nuts spare if needed. PM me if you need some.

Thanks for the suggestions everyone! This morning I popped round to my local motor factors and picked up a 14mm socket that has 6 rounded lumps inside it that grip the faces of the nut rather than the edges, and I have loosened it��.
UK GS Nut - Thank you for your very kind offer. I will PM you in a short while.
