Threaded bolts (argh!!)

**Antallica** · 29th January 2005, 16:21

Hey all,

Now that I've sucessfully broken the Bandit for a while, I need to figure out how the hell I'm going to fix one of the threaded bolts that I managed to break so easily when putting on the oil filter cover.

By the looks the whole threaded bolt might be able to be screwed off the engine itself, I'm wondering if one of the local bike shops might be able to have some replacements (sadly I can't do that until Wed). Anyone else done this before?

What a shit day.

so its the bolt thats broken or the hole it goes in to?? Any fastner shop ie EDL fastners should be able to do the bolt, and the hole could easily be repaired with a helicoil

Well here's my shoddy attempt at making this more clear.

Tap and Die set will sort the prob

I'll still need a whole new bolt rod won't I? It's unrepairable?

Yep you'll need a new one. Luckily its and outy you are having problems with not an inny (so ignore Wkid you don't need no tap or die). Get some vise grips, borrow some if you don't own any, lock them onto the stud and then turn it outwards. Keep undoing the vise grips and reattaching and turning until you can get it out. Go down to the shop, any sort of engineering supplies shop if the bike shop doesn't have the part - take both bits with you and say I need a stud this long (sounds like girl talk, but thats what you need). Then bring the new part home, screw it into the bike and you are ready to attach your oil filter cover again. To avoid breaking it again don't apply gorilla grip force when you do up the nut, its just a teeny weeny stud.

It's called a stud,has a thread at each end.I don't think you will find a stud or bolt with that thread at Mitre 10 (where do they get the staff these days?) or anywhere else for that matter.All the nut and bolt suppliers stock ISO threads...that's international standards...so the whole world uses that metric standard - uh,except the Japanese,who in their infinate wisdom have a whole completly different range of threads (does whitworth ring a bell you old farts).Because we all ride and drive Japanese vehicles we think the Europeans are doing it all wrong with their weird theads and hex sizes (11mm,13mm,15mm etc) but in reality it's the Japs who are doing it wrong by not recognising international standards.....end of rant...

Every component we replace or vehicle we wreck has every nut and bolt saved and filled in boxes - because we can't buy them.Bring me a sample if you like.

Well that explains a few issues I've encountered over the years with owning both Japanese bikes and European cars (well a Renault 12 - now that was an idiosyncratic engine/diff/gearbox layout - although I think it was the Renault 16 that had the whole thing backwards!?)

So what threads are used on the pre-packaged bolts/studs etc at places like Repco/Supacheap Auto? ISO metric?

So what you're saying Motu is that the engineering or bike shops won't have the bit?

Try MSL Fastners on Rosebank Rd (big orange/blue building, with a big arse bolt out the front) i had the same issue when trying to find a bolt to use to fit my crash bungs, they generally are used to selling to tradesmen but they should have what you need. A shop like this would be your best bet, trying to get it from a bike shop would be a mission and a half.

When you thread the stud back into the eingine case might pay to slap a little loctite in for good measure.

Cheers

Sorry didn't realise you're in whangerai, rosebank rd just a little to far, MSL may have a branch out your way or try any place that deals with fastners.

A bike shop would be a better bet,they will have Japanese fasteners,and like us will save every bolt to spare.I've had salesmen from big fastener suppliers say they have every thread for there is - ''have you got one of these?'' says I showing him a 10mm 1.25 standard Japanese bolt....''ummm,I'll get back to you on that one''.They never do,cause they don't have them!

And BE GENTLE,go at it like a bull at a gate and you`ll just snap it off inside the casting,then you`re in the shit.They`re not the strongest of things as you discovered when the other end broke.Best thing to do is dose it with some kind of easing oil or WD40 or similar,ease it out a bit and loads more gunk.Even if it seems free enough dont take any chances,trust me mate I`ve learned patience with machinery the hard and expensive way.
