Broken bolts

16 posts in this topic

I was working on my bike last night (650r) and had it all back together when I was tightening the pinch nuts that clamp over the front axle and SNAP I broke the bolt. I took the cover off to examine and found I still have the stud sticking out. I tried to clamp on to it with a pair of vise grips, but couldn't get the stud to budge. My question is how do I repair this. Are these studs threaded in or pressed in? I wouldn't think they would be pressed in. Do I need to drill it out and re-tap it? Anyone with some advise, I could use the help. Thanks

Drill and tap..... Best way

Wrong!

They are studs and are just threaded into the fork leg. You need to get a better gripping device to grasp what is left and twist it out. I went to the store and got a HUGE pair of channel locks that gave me the leverage to grasp it and easily twist it out.

Just head down to ACE hardware and get a replacement stud from their metric bins. Take the broken stud for referance.

Docmarkw-

What city do you live in?

There is a guy in Gardena that electroincally will remove the stud. no muss no fuss.

So if you can't get it out and you are near the L.A. area I'll get you the info.

Right on Jack! I did the same thing when I first got mine. I looked at it and was like &%$#@!??? is this a stud. Then I smacked myself and got the piece out. I was picturing me, bent over the dealers desk, buying a new lower fork. LOL

I actually broke both the top studs. I broke the first one I think when loosening it because the stud gave a little pop sound and when I re installed it the nut snapped at hardly any torque. I don't think this stud is going to be all that easy to get out (This is the one I applied the vice grips to and couldn't get the bolt to budge) . The other stud snapped at a little more torque maybe because its got the load from the first stud to compensate for. Fig I'm in Ventura County if I can't work this out I may take you up on your guy.

Mark, This used to happen to me all the time when working on Camera Cranes. You should heat the area beyond belief, heat is your best friend, it'll come loose... You can either use a heat gun or butane torch, channel locks never works for me, I just can't grab it as good as vise grips. Heat my friend, heat... Take the bike over to Johnnys house, the guy will fix it..

Hi Dan, I told John about it and he said the same thing you did. I am a little reluctant to but a propane torch to it.

Went home for lunch, put the heat to it and it came out easy. I feel kind of embarrassed for even posting this. The stud is a 6X34 mm. I have a trip planned for tomorrow morning and need to find this stud ASAP no Honda shops in the area have my part in stock, the Honda shop where I'm going doesn't have it in stock. My other brand shops don't have anything either so my question is where am I going to find a stud this fast. Another option is could I use a standard 6X34 mm bolt? I would only do this as a temporary fix until I could find the studs. Any suggestions?

Mark,

option 1) Call Dave at Simi Cycles 805 522-3434 he's got tons of bolts in stock.

option 2) Use a stud from the other fork leg, two pinch studs on each side should get you going...

option 3) Come over to my house, I've got a lot of stuff here.. Maybe the bolts on my WR will fit, and maybe you could use a bolt instead of a stud...

Problem solved for now. I found some allen head bolts that work great. I'll replace them with studs when I get back. Thanks Dan for the offer, very kind of you to offer parts off your bike.
