removing rear over riders

[daverclasper]

Hi folks

 

Are the rear  bumper over riders  on vitesse/herald difficult to undo, due to seizing up, as I've they can be.

 

If so, any tips on this please.

 

Cheers, Dave

Yes. 

I will clarify. Triumph is their infinite wisdom use a square nut in a cage attached to the over rider. Right where mud/water/debris gradually accumulates. When you try to undo the bolt in the boot, unless it comes undone easily, the nut starts turning in the cage. Then you need to get clever.

Oh, and teh bottom bolt goes through a tight fitting tube several inches long.

 

You may be able to cut the bolt head off (to be fair, the top bolt is less of an issue) and then knock the overrider off using a drift on the now-headless bolt or just tugging.

 

Once the overrider is off use of mole grips etc enable the offending bolt to be unscrewed, or otherwise removed. Repairs to the nut cage usually required, sometimes knocking it back into shape, sometimes a bit of welding.

 

I have seen, and indeed repaired many such overriders by welding a length of studding to the square nut, and the using a nut inside the car (so it doesn't suffer from corrosion/mud/grot)

 

 

And of course access behind the fuel tank is very poor, so that usually needs to come out.

 

All above worst case, you may be lucky!

Mine had studding as clive suggests , and wing nuts inside the boot , made removal easy if needed

 

you could twirl the wing nut with the tank in place but only removed them once in 13 years

Thanks a lot for your replies.

 

Really useful. 

 

Always good to know what your up against before you start a job.

Wing nuts are a good idea, never thought of that!!
