Exhaust fail

[MOD500]

The exhaust became very noisy over the space of a mile.

 

I don't think I need a leak test to see where the problem is.

You don't need an exhaust the world needs moar noize

[Mally]

Looks very weldable.

[Andyrew]

Quick weld should fix it.

 

Question is, why did it break?

 

Looks like a stress crack.

[sierraman]

Gun gum is absolute crap. A smear of tiger seal on that id give it.

That is the question.

 

They like to rattle themself to death for fun. Normally it starts with a weak rusted through section but this went in one spectacular go.

 

I think the heater pipe I recentlý fudged has been pushing against it. I would have thought so given it's flexible, but I don't believe in coincidences!

 

I'll probably swap it with a spare for expediency then weld out on the bench.

 

Shit. I'll have to clean the bench.

The car is very underpowered.

The accelerator is now the noise pedal.

Weld a couple of corner fillets at the break.

 

 

 

 

 

 

 

Then it will break somewhere else next time.

It looks a bit like a Cyclops playing a didgeridoo.  

 

HTH.

Ain't that the truth!

[MOD500]

It turns out I had lost am exhaust bracket bolt. The one that's under the exhaust and can only be seen when lying on the floor. Something I generaly try to avoid.

 

The bright marks on the exhaust show where the strap was rubbing.

 

 

I don't mind repairing when I know what caused it so won't be doing the same job on a few weeks.

 

Annoying I had picked up on the rattle on Thursday, but I normally leave rattles till the weekend.

[MOD500]

The break was fairly clean and the metal is thick enough for a good weld. It's always a bit easier when welding to a manifold. There's a lot less chasing of holes.

[MOD500]

This was being done while it was rain. During the dry spells I thought I'd get in a bit of golf.

 

New bearings needed. With the offending hub removed there was a strong smell of death oil. Like that horrible smell you get taking apart a seized engine.

 

I know the golfs aren't everyone's cup of tea but this, like most jobs on the car is easy peasy lemon diseasy.

 

 

 

I took the old bearing racer, cut a slot with a 2mm cutting disc then used it to drive in the new racer. Then the old racer could be teased out with a screwdriver.

 

[MOD500]

Carried on with exhaust....

 

Welded up fine. Not the tidiest but i don't care.

 

Had to use a rotary grinder to clean some weld from the inside.

[MOD500]

It was going so well I decided to slow down the pace by attempting to sever my thumb off.

Superglue is great.

 

 

Bit of a hassle manouvering it back into place but it's ready to go.

Bootlid = tool shelf.

 

 

This is one of those moments where having so many tools allows the right combination for the job. Turning this from a knuckle grazing nuisance to a relatively simple job.

Is it a 498cc engine or the 652cc one out of the 126? My 126 was a right bastard for shaking itself apart, especially seeing as I was 19/20 at the time so it got driven flat-out all the time. The original cylinder head had to be tapped out to take 3/8" (shank diameter) Whitworth bolts because the original 13mm holes (a/f) stripped. The replacement head had been helicoiled prior to me getting it and having a 2mm skim...

 

Edit: I'm assuming it's a later engine as it's got the wasted spark distributor cap.

[MOD500]

It's the 594cc from an early 126.

I prefer the 652cc but I swapped them to diagnose a fault. Using a sledge hammer to crack a nut.

 

I'm very slowly working on a 700cc with a modified can, panda 30 head.(twin inlet) and twin carbs.

 

126 was my first car. They were dirt cheap in those days. Had loads of fun in that thing! Many sideways roundabout trips, parked it in a trolley bay, drove it over a public foot bridge.

[MikeR]

The alternator bearings always went on mine .....but i did have a another 126 that was running on 1pot ... It could backfire to order !!!!!

Disappointed with the lack of flange gag there 2/10.

Too tidy. Needs to be more half-arsed:

Aye, you want to be careful using the Dramal 4®

Nothing less than a vajazzle will tidy up that flange.
