Sheared Nut !

Have you ever been under a landy and asked yourself 'Why the F*** did I start this job!!'?

After my success of doing a nice job replacing all the rotten window channels on the Saturday, today I thought I would cure the noisy exhaust (and fumes coming into the cabin.)

After a brief look along the length of the exhaust I found the problem - the three nuts/bolts that hold the exhaust to the manifold were a bit loose.

I'm not sure if the exhaust is held on here by three bolts or if the arrangement I had - two bolts with a nut used to butt against the flange (no jokes please!) and a third being just two nuts against a downward bolt ????

I had successfully tightened up the two bolts with a nut used to 'lock' against the face of the manifold flange.....but upon tightening up the third 'lobe' of the flange the bloody thing sheared off:



Once I had a close look, I found that it wasn't a nut - but a bolt and a nut that had been butted against each other !!





Does anyone have any advice as to the best way to extract the remaining stud now the bolt head has been sheared off ???

There doesn't seem to be enough space to get a drill in there (unless I can get a very long thin drill bit) !!

I think I would be removing the manifold and sorting it in ghe workshop...

Will be a lot easier that way.

I concur. But I got a friend who worked in an engineering shop to take the studs out!

done the same meself...fookin studs break fer a pastime

long series drill needed methinks

Hello!

I'm a newbie here.

I was avoiding posting till I put up an intro with photos etc but I feel I can contribute here.

While I have only just got my 1st LR (Series 2A cab/chassis), I'm no stranger to sheared bolts: Jags, MG's & esp air-cooled VW's.

Do you have a MIG welder or access to one?

Put a nut over the broken stud. It needs to be just fitted on, threading not essential. Then fill the hole with weld. Do not unwind untill really cooled off. Like go to lunch or leave overnight.

Sorry but 4 decades of encountering busted bolts has taught me that "Ezy-Outs" & their ilk that you counter screw into a hole drilled in the stud are not worth a crumpet. They only work on easy jobs (hence the name???) & when the going gets tough they break, with regularity, leaving you with a super hard insert inside a stud that now can NOT be drilled out.

If the weld does not work, keep drilling it out wider & wider till you can put a tab into into it to restore the thread.

Good luck!
