Fuel tank strap bolt

One fuel tank strap bolt has come right out so will be replaced, the other is gash but still welded (I presume) into the strap end. What's the best way to get it out? Drill it? angle grinder too big to get into the head of bolt to chop it. I've tried running a new nut onto the thread but its not for going, just too rusty/cruddy

 

chew it off with yer bear teeth grrrrr

 

But I'm all woman

 

oh yeah I forgot about your mooobs and your girls voice

see if you can see the welds that hold it in and cut through them, think theres 2 , dril ing through probably wont work as the welds are on the out side edge

 

Forgot about my moobs? You couldn't keep your big bear hands off em
Tried getting the chisel in for a whack but maybe my lady hands weren't up to it

 

get one of those polish chaps with the frim buns across the road to help you out x

 

Aah yes their firm buns are very in demand

 

Wire brush the thread with a dremmel type tool untill its as clean as you can get it
Then use a die or a nut with a slot cut in it to chase the thread clean
A dab of oil and small back and forth movements is the key

 

tried a wire brush but didnt really help. will try again next time im allowed out for "other duties"

 

Is it the nut (in the recess the gearbox mount sits in) that you cant free off? ...it should be on a threaded bar which is welded to the petrol tank strap...not a bolt if Im thinking of the right bit

is the engine out at present? ....if so, remove the fire wall bulk head also

You could easily shear the stud/threaded bar off the strap, or end up tearing the meatal of the strap if your not too careful

I would clean as much rust off of the nut as possible first, then spray with a good anti seize spray/penetrating spray over the course of a day leaving plenty of time to work in. Next get an adjustable spanner, use the spanner to hold the metal of the bracket at the end of the strap still from inside the petrol tank area (this will help you get some leaverage and stop you ripping the metal strap), then use a socket on the nut underneath..

if it still wont budge, get a blowtorch on the nut, get it red hot....leave the heat on it for a good while.......then turn off the blowtorch and repeat above method

....mine wouldnt shift until I used a lot of heat as above.

when undoing the nut, every half a turn as you undo, retighten by 1/4 turn to stop the thread geting locked by bits of rust

failing that, you might have to cut, but it will be a bit of a pig of a job getting in there to cut without damaging the threads of the stud

 

Aah mr diddymen, such a comprehensive reply, alas it was only this I was referring to


I wish to remove the bolt from le strappo....

Ps. Nikky nokky noo song??

 

Its not a bolt its not designed to come out

 

I know but as the threads are mashed I need to remove it and replace it with a new bolt

 

I drilled mine out, but it is fiddly. You could cut it out and repair the cradle it sits in.

 

As above re drilling but I cut what was left of the threaded portion flush with the bottom of the strap then drilled down through the head of the bolt but I was lucky to have a small portable vice to hold it steady but you could clamp it with mole grips etc.

Both of the threaded portions must have been cut at some point and were so short they were held on by around a turn on each nut - all the closed cell foam had been removed too so chafing abounded!

 

Dear mr bat, here's what to do, get a socket from your socket set that's big enough to fit over the welded in round bit, place the socket against so etching hard with the stud sticking up, whack stud with big hammer, hey presto weldo a broko

 

I had the same issue.. I ended up cutting the litte cradle bit at the corners so I could bang them flat, then use a grinding disc to grind off both sides of the bolt.. Then re drill the hole, stick a new bolt through, bend the ends back and re weld it all together.

Pig of a job.
