Looking for an engineer

[jacob]

Hi all,

I'm looking for someone to remove a bolt which has snapped off in the cylinder head of my 1967 Honda S90.

Does anyone have any recommendations of someone or somewhere to get this done (in Auckland)?

I Don't know about engineers in Auckland but welcome to the site.

Good luck with the Honda.

Hi and welcome. Any car or bike workshop would do it, it's not an unusual thing. It's actually not that hard to do yourself in many cases, depending on access. Get a set of ezi-outs from Repco or wherever, drill into the the broken bolt, screw the ezi-out counter-clockwise into the hole you've drilled and out comes the bolt.

Sooo many people break easy outs off it isn't funny. In my last job we were always cursing the bastards... makes getting the stud/bolt out heaps harded.

A neat tricl is to leave it soaking overnight in penetrating oil, then use a reversible drill with a left hand twist drill bit. As you drill into the stud, it'll grab, and wind it out Of course, you might just make a mess...

The penetrating oil's a good tip (shoulda thought of that meself). I'm no engineer but I would have thought breaking an ezi-out would occur mainly because someone used too much brute force. Possibly also using too small an ezi-out relative to the diameter of the bolt. If the bolt won't come out fairly readily, I'd give up and I'd take it to a shop before I broke something.

Another good tip with using Ezy-outs is to use the largest one that will fit in the bolt, and drill two or more holes: drill one of a slightly smaller diameter than the tip of the Ezyout, then another slightly bigger one not so deep, then a third (if possible) slightly bigger/shallower. This way you maximise the surface area of the Ezyout gripping the sides of the hole.
Other tricks are to heat the area with a hot air gun, lighter or whatever before putting the penetrating oil on, and if you can heat it again before trying to extract the snapped bolt and cool the bolt itself with a can of freeze spray, it may be enough to loosen it.

If all else fails get a farkin' big drill, fill ithe hole (and everything else) with explosive, light the touchpaper and run like hell.

Nah, it was only five and a half.
But I've got three troglodytes living in my house, and they've reminded me that blowing shit up is good.

So you live in a cave? With 3 fellow cave dwellers ..who like to blow shit up?
Have you considered moving?

Four. Four troglodyteo. But I'm married to one of them, so I can't call her a troglodyte or she'll get mad.

Ayup. I offered to chuck myself out.
I mean, all I need is a change of clothes, my credit card, and the bike, right?

Axe Shirley, I'd rather just blow the cave-house up. Blardy thing pisses me off. Too much work, not enough playing with the bike / drinking beer. Luckily I'm not called Jack, or it'd make me dull.
Instead of just (what's the currently PC term?) ... ah yes - "suffering from a mental illness".

Yeh i love that philosophy...mind due it didnt help my dad being fully ICI certed when i was youngin.... When you ask your dad what he did when you were 5, did he blowup the sandpid to show you....only to get your tonka scraper sitting on the neighbours roof? Mine did

[froggyfrenchman]

Im engineer! *smiles proudly*

Christ im pathetic

they are tapered, as you screw it in if there is not too much of the bolt left it can spread it out locking it in.

Another tip is, if the bolt/stud in broken below the sutface drill out the first bit of thread in the hole as this will inevitably be damaged making the broken bit harder to get out.

A method I have used for years is to drill a hole in the broken stud, then hammer a "Torx" bit into it, they are very hard and bite into the stud and because they are not tapered they do not spread the broken stud. Never had it fail yet, give me a ring on 09 424 0477 ask for Tim, my garage is in Whangaparaoa, bring it over and I will do it for you.

If the thread is damaged I have metric "Time serts" to replace it.
