Cracked swing-arm?

[Mike.Gayner]

Having taken the bike out for a good ride today I was cleaning it this afternoon and noticed a nice new crack in the swing arm. Fuck. Is this terminal for the swing arm? Or can it be welded? Is this ordinary fatigue, or has something extraordinary caused this? I suppose I'd better stay off the bike until this is sorted.

[kevfromcoro]

My mate had the same thing happen on his duc..
Motor dropped down, and tore all the vacuum lines off the motor.
He was a welder, and was able to get it to work and tig it up.
No more probs

Seems a strange place to crack

I'd still ride it. Just don't go too silly until it's sorted. And decent bike shop could tig that up for you.

[nzspokes]

I would be looking for a new one myself. Welding as a last resort.

[Mike.Gayner]

My thought as well. I just had the chain done, any chance the mechanic has torqued the tits off the axle? I haven't touched it yet to find out....

Why do you say that? Have a look at the swing arm in my SR.

[Mike.Gayner]

I should mention that I work for the NZ Welding School (I just do accounts...) so I should be able to get someone skilled and experienced to look at it soon enough.

I'm pissed off having just bought the bike 2 or 3 weeks ago. I'm 95% sure it wasn't there last week.

Would you grind it out and lay a new bead, or just tig straight over the crack? It's going to look like shit anyway, isn't it? Not that the look matters much when compared with several hundred dollars for a new arm.

Swing arms on TM seem to go fairly cheap. Bike dependent of course. You may be able to get one for the cost of welding. But as he works for a welding company then he should be fine.

I would be checking the torque on that nut though.

[Crasherfromwayback]

That'll have nothing to do with it unless there's spacers etc missing.

[ducatilover]

That'll have nothing to do with it unless there's spacers etc missing.

Shouldn't crack there regardless of spacers, you leave a spacer out and the swinger will pull in and bend further forward. And assuming it's a semfiddy teapot it should have a solid axle slider in the swingarm anyway.
I'd say it's just being a Suzuki :whistle:

Welding it will be fine. Should be enough there to vee it a little and then polish out

The factory sticks the whole frame together with weld, why wouldn't you weld it?

[Ocean1]

The factory sticks the whole frame together with weld, why wouldn't you weld it?

Because welding it anneals it, some alloys to about the consistency of chewing gum. The factory also heat treats the finished assembly.

The shop guys should be able to sort that if they know what they're doing though.

No doubt. And if they know what alloy it is they can probably even temper it.

[Mike.Gayner]

Someone else pointed out that these two marks could be related:

Neither the marks nor the crack were there before the bike went in for a chain - could this have been caused by the mechanic, or am I barking up the wrong tree?

Well it will depend on what its made from and if its heat treated. I believe some self anneal with time but others have to be baked.

I have photos of the bike from 2 days ago that show the marks aren't there.

Yup, and some work harden.

And until you know what it is you won't know how to treat it.

Let's see 'em then.

[AllanB]

Barking up the wrong tree - I fail to see how any mechanic could do that to your swingarm. Probably just some Suzuki thing. Weld it up and have some race lift bobbins attached while you are at it :yes:

Search Suzy forums - probably happened before.


I'd see it as a positive and e-mail Spondon Engineering in England and aske they make me a spiffy new one!

[Mike.Gayner]

Cheers, yeah probably had nothing to do with the mechanic, would have been nice to have someone to blame :(

Here's a picture from a few days earlier but it's only from my phone so you can't really see anything. I have some better pictures somewhere around.

http://i.imgur.com/L9xPLKg.jpg

edit: To be clear I'm not blaming my mechanic at all for this - I have a lot of trust in him and I was just in a shit mood hoping this was someone else's fault.

[Mike.Gayner]

BTW what's the going rate for a used swingarm if I should find one? They don't seem to fetch much on Trademe, but hard to tell when you're being model-specific.

[AllanB]

Trademe $100-$200, higher from a bike breaker usually. Depends on the bike and desirability of the swingarm. I sold a old school alloy GSX1100 swingarm I originally purchased as a upgrade for a old Kawasaki for good coin - lots of bidders as it is a popular one for older Kawas and Suzukis.

Teapot swingarm should be pretty cheap. Welding probably cheaper!

[SS90]

Welding it wont be a problem, and totally acceptable but just be aware that it shouldn't be able to pass a WOF afterwards (assuming the tester follows the law), it's a major load bearing suspension component, and as such is it allowed to be modified, someone could argue semantics about this, but it's not (as far as the law is concerned) legal.

It would have to be crack tested to pass MOT's...... Hopefully a welder can arrange this, but it has to come off the bike to happen

Most guys would likely pass it... Im just playing devils advocate... It will make it harder to sell later too.

That said, in my opinion, it's totally safe.

[Mike.Gayner]

Cheers for the help.

I can get it X-rayed through work for about $75, which may be cheap peace of mind anyway. I'm still on the lookout for a used swingarm if I can get one at a decent price.

[The Reibz]

Thats a piss easy weld.
Swingers are made of good Ali. Not like the horrible cast iron in casings which never weld easily.
Seriously easy weld.


I Graduated from Pap NZWS in Jan last year.

[Mike.Gayner]

Awesome mate, I started with NZWS March last year, but there haven't been a lot of staff changes since then so all the guys are still there.

[manxkiwi]

Looks suspiciously like the axle has been tightened without the adjuster being inside the SA. That's exactly where it would crack if this was done.

Drop the wheel out and see if the adjuster is now very tight inside the SA. This would show for sure if the SA has been 'squeezed' in. Also throw a straight edge vertically on the SA and compare both sides for deformation.

There's probably nothing you could do, even if you found this to be the case I guess?

[Crasherfromwayback]

Looks suspiciously like the axle has been tightened without the adjuster being inside the SA. That's exactly where it would crack if this was done.



I'm not thinking that'd do it. The axle spacers etc should take the load...not the axle adjusting block. If that took any load...the sa would still distort when tightening up the axle.

[manxkiwi]

I'm not thinking that'd do it. The axle spacers etc should take the load...not the axle adjusting block. If that took any load...the sa would still distort when tightening up the axle.

But the swingarm is hollow and the axle adjuster assembly is fully load bearing. If the adjuster block isn't in place the outer wall of the SA will cave in under tightening pressure, surely? It's only a thin piece of extrusion after all. If a wheel spacer were missing, the whole arm would flex I'd imagine. That crack is exactly where you'd expect to see it if the adjuster wasn't in place.

Nah. If the axle adj plate wasn't there I'd still not expect you to be able to crush the sa unless there was a spacer etc missing or in the wrong place. The sa is still thin enough there that it'd crush even with the plate in if there was another *issue* think you'll find.

[Mike.Gayner]

I'm going to pull the end cap off tonight and see if there's any signs of anything like that. In any case, as you say there's not much I could do about it.

[Mike.Gayner]

This is how the SA and axle adjuster fit together: http://imgur.com/1Fl7sFC.jpg

This is the chain adjuster itself, which presumably takes all the load - I must say it's a flimsy looking piece itself, though hard to tell without seeing it in person: http://imgur.com/AzM2876.jpg

Yeah, I didn't mean the plate supports the SA. The threaded adjuster bolt is welded to a spacer with a hole in it that the axle goes through and fully supports the SA structure. Lots of Suzukis have this set up.

Anyway it's all a bit academic as the OP still has to remedy the problem.

[manxkiwi]

Just looked at that picture. The threaded bolt isn't welded to the spacer in this case, rather, it screws into the adjuster block. I'm imagining that piece number 16 wasn't in place, thus no support for the extrusion. I'm only guessing of course, based on one photo. But that's what it looks like to me.

You've been in Germany too long dealing with their TUV is it ? Never be noticed here....

If it gets welded, yes, off the bike - and a dummy axle and spacers inserted to maintain the arms parallel.

Mr ocean, pretty well all Suzuki alloy fabrications are in an air hardening alloy which can be welded no probs at all. can't remember the numbers but the alloy used is very similar to the Italian Ergal ones - and unobtainable here...

[Mike.Gayner]

Images with the end cap off - notice the direction of the crack. At least it's in one piece still. I feel confident enough to at least ride it to the shop/engineers/etc.

you forced me to go and look it up....

the arm is most probably 7003,7004 or 7005. the japs have been using this from the beginning of their alloy frames and bits. it welds well with commonly available fillers. AFAIK 5356 is probably the best choice for fillers. Pro welders feel free to chime in....

Good to know. I wasn't being pedantic without good reason, though, the strength of most extrusions in particular are dramatically affected by welding.

Can't go too far wrong with slices from the parent material. If there's none to spare find a wrecker...

[Drew]

Seeing that...I wouldn't even bother getting it welded unless it worsens.:gob:Really?

I'm perplexed as to how it cracked. I imagine a mechanic wouldn't do the axle up without the adjuster spacer in there. But I equally wouldn't expect to see the axle nut with fresh damage, usually caused by using the wrong tool to undo it, or the right tool improperly.

In any case, there's not an easy way to tell. The swingarm is not experiencing it's biggest forces at the axle, but it's still taking a hammering and trying to fight twist back there.

[Crasherfromwayback]

:gob:Really?

.

Really. They guy is not road racing it, and it ain't right through the arm. Just keep an eye on it. Not like it's all of a sudden gonna break in half.

[Grumph]

Good to know. I wasn't being pedantic without good reason, though, the strength of most extrusions in particular are dramatically affected by welding.

Oh, quite...What is pretty obvious is that the japs did a lot of research when they started making alloy frames and arms. They came up with a weldable medium/high strength alloy which air hardens post weld - but only to a safe level...Ideal for production line welded fabrications.
Having done that they then secured a source of supply which seems to be restricted to Japan.

More on this family of alloys in The racing Motorcycle Vol2.

[Drew]

If the swingarm was faulty from manufacture, I think it's good for naught but scrap. Whether it CAN be welded or not.

Serious question like, how can the guy be encouraged to ride on something with an obvious flaw as this?

[buggerit]

If you look at the photo of the extrusion you will notice they have created a stress raiser by the way they made the extrusion to
create a slot for the axle end plates to slide in, thats why it cracked where the wedge shape finishes.
I would drill the end of the crack, vee out , tig up and then clean the weld back so you dont create a stress raiser each side of the weld.
I would also weld it up clamped up as it would be in use .
I would pay to have a look at the bottom of the swingarm in the same place and the other side.

[Mike.Gayner]

Thanks, did this last night and no signs of cracking - I'll keep an eye on it though.

[Crasherfromwayback]

Serious answer. Keep a close eye on it and see if it stays as is. I'm not saying he should leave it forever. Merely that I'd happily continue to ride it until I found a replacement or had it welded...and if it doesn't get any worse whilst I was doing that...I may do nothing about it. Like I said...he ain't road racing it or jumping off tall buildings. There's every chance it won't change if everything is in place as it should be now.

I made several aluminium swingarms having seen the original factory MX offerings. Still twin-shock but with serious angles. Never got it quite right.

I once picked up a late 90's cr250 frame in one hand and an sx250 frame in the other and wondered why Honda bothered. Especially with all of the bleating about them being "too stiff". Years later I read a piece pointing out that aluminium frames are capable of being manufactured robotically, whereas steel tube frames weren't, (then).

I tend to agree but WTF do I know?

I spoke with the mechanic who did the recent work, and he rightly said that he cant really comment without seeing the bike. In any case, my plan of attack for now is to get it V'd and welded soon and keep my eyes open for a decent used swingarm in the near future. I have a good wrecker friend who reckons finding one will be the hard part, but the going rate is only about $100.

Aluminium cracks love to play creepy crawlies; it's a bit huckory, but chucking a decent diameter hole right on the end of the crack stops em moving if it wasn't done cos of operating stress, and provides an easy check mark if it was!

[Mike.Gayner]

Showed the pictures to a mechanical engineering friend with some experience in materials - he reckons damage caused by crushing (e.g. overtightening with the spacer missing) is unlikely - it would cause permanent deformation and there would be other obvious signs like bruising. He says "If those fibers had enough stress in them to start a crack, it should have formed at the weld across them at the shock mount".

He also says "An extrusion defect seems the most likely as they are typically longitudinal however even that is unlikely.", and he's otherwise perplexed like everyone else.

My best guess at this point is a manufacturing defect that has eventually resulted in the crack. But I'm no engineer.

Yeh, you'd have to be a particularly ham-fisted operator to smush a swingarm of the size wall, even then, and like he said, you'd get other signs too. Have you had a good look around for stress raisers (tight radius bits, chips and deep gouges etc) along the crack on the inside?

Nothing obvious that I can see, but the truth is I really don't know what I'm looking for. I havent had the axle out yet though. This is all I can see at the moment. http://imgur.com/I6WuwcR.jpg

[manxkiwi]

I'm still going with the no spacer option. Tell you what, when you drop out the wheel, re-assemble without the spacer and give it a wee nip. I'll wager the crack will open and flex back when you back it off.

[imdying]

I'm with you. I'm no engineer and having nothing technical to go on, but I have found that with Japanese motorcycles, failures seem to be more often than not boiled down to some sort of human error. If it were an old British bike, or an Italian bike, just crapping out because of defective parts would be much easier to swallow.

That would be a mission considering this bike is set up as a twin shock.

edit: type-o

[Flip]

I suspect it cracked because the axle bolt was not done up tight enough. Its an aluminium extrusion so its perfectly weldable. Do check that the correct spacers are in the wheel.

I would however get it done by a qualified welder, not a bike mechanic, student welder or some body who works for a welding supplier. Just pull the swing arm out so there is no chance any stray earth currents don't fuck your electronics.

What the fuck do I know about welding anyway.

Found a used replacement swingarm for $150. Sorted.

[Mike.Gayner]

Received used replacement in the post today - this one also has a crack in it. This time on the inside non-drive side. Not sure whether to be pissed at the wrecker, Suzuki or both.

http://imgur.com/xbK42Ou.jpg

[bogan]

Gutted, I'd give the wrecker an earful assuming you asked for a anon-cracked one. From that photo, I wonder if it isn't some flaw in how the axle hole was made. If it were punched out without the proper sized spacer, that would put a lot more stress on that area than it would see during the rest of its lifetime.

[Mike.Gayner]

In fairness I didn't specifically ask for a non-cracked swingarm, but I didn't also ask the cafe for my coffee to be free of cat piss either. Certain presumptions are probably reasonable.

Wreckers tend to sell parts as-is, 'well it came off a runner' is about the only expectation you can have. Hairline crack on inside edge of a grubby and bashed up swingarm would be easy enough not to spot I reckon.

[Mike.Gayner]

Showed the picture to my mechanic engineer friend (and clarified this in this case the crack is centred about the axle hole and doesn't reach the end of the swingarm) and his best guess at this point is a design flaw that allows stress upon the radius when the axle is tightened. Probably due to an improperly sized insert/spacer. Gotta agree at this point I think.

edit: Yeah bogan fair enough. I wish I could have inspected this part before taking it, but the wrecker sent it down from Auckland.

I'd be asking him to take it back and refund you as you were replacing a cracked one. If he's a fair/decent cunt he'll do it. If not...tell him to stick it up his arse.

[Rhys]

Must be a common manufacturing fault

[buggerit]

I would pick that either the tube spacers are crushing/deforming under use or they are originally manufactured with to much clearance
between the ends of the bush and the swingarm, either way I would be making more substancial bushes with minimum clearances and
weld up swingarm

[Drew]

I'm surprised by the second one being cracked also. It would seem to be a very common problem, or you're the unluckiest cunt ever.


Google searches only seem to show up your threads on the matter, so can't be too common.

[AllanB]

JB Weld it and a coat of paint mate ...............


Interesting as it may well be a factory issue. Wrecker should take it back IMO.


Feel for ya as it would fuck me off knowing that could happen on the other side after welding it up. Again I'd use it as a good excuse to call Spondon in England .......


I wonder if the GS1200ss swing arm would be a direct bolt on - I suspect so.
