Front axle holder bolt broke

Matt G · Veteran Member

Hi,

The pictures below show the bolt that has broken. Has anybody seen this before and what is the best way to fix it? I was putting on my new disk that I just got from Brian and I snapped of the bolt. disbelief I have gave my torque wrench to my Dad and was to eager. cry

Thank you,

Ha ha, Thank you Brian. They look great. Do you sell the bolts?

A mini pair of stillsons 4 to 5 inch should do the job
or better still use a thread die to extend the thread on the damaged stud so two nuts can be screwed on, lock the two nuts together and remove stud with a spanner on the bottom nut.

Sorry Matt but we don't stock them. First time I have ever been asked!

Thank you Brian and Colin. I will try with the stillsons.

I had a go with the stiisons but it will not move.

Looking at this diagram I don't even think they sell them? I will call the local Yamaha dealer on Monday and see what I can do. Having a look at google guys have broken them before on other dirt bike brands and have been able to replace them so you would think I can on a Yamaha.

If a replacement stud is unavailable then use a bolt cut to length to bolt it up after you've removed the broken stud.

This is fun, they broke me two of them years ago, it is easy from replace, the unique problem is retires the older (for you will be easy because it has broken in a good position). When you retire the old, only you need cut the head from a screw with the same size.

About other curious thing, the plugs from screws, they can be easily bought at a screw store (perhaps it is not the name from the store but here where you can find screws, you can find the plugs a lot cheaper and even better than the originals).

Hi Cubber, I called the local Yamaha dealer today and they can replace the stud. I spent a few hours on Sunday and I can't get it out. I was thinking about putting a nut on it then just tack it with the TIG so I can put a socket on it but have decided not.

Hi Nomada, That is a good idea but I will get the local Yamaha guy to pull it out and replace it with a proper stud.

Hi Did exactly the same thing.

Buy a stud extractor to fit

10mm if i remember right.

Its a lot easier and you dont loose any skin.

Also invest in a low range torque wrench with short handle.

Its amazing how little you have to tighten these small nuts/bolts.

Good luck

Just to finish the thread off.

I was able to get a new stud from Yamaha for $2.80AU (1.86GBP) and all is well again. I also brought a smaller torque wrench so I don't make the same mistake twice.
