ok so i was trying to fit hilows yesterday and after 5 hours of trying to get the old setup off i just couldnt, i used everything screwdrivers chizels, hammer, wd40, and it would not come off.



where the end of the donut meets the subframe if well and truly stuck and there the donut meets the aluminium come its well and truly stuck. no amount of force seems to be able to get it to come out.

so any suggestions?

If you are not worried about keeping the trumpet, break it.

A very common problem unfortunately.
You could use some penetrating oil, as opposed to WD40 which, contrary to what some think, is not a penetrating fluid.
Then just use a big chisel and lots of force.
Alternatively with a long pry bar you may be able to get the trumpet & cone out and separate them in a vice, but take care not to shatter the trumpet, which is easy to do.

I resorted to chopping my trumpet after about n hour and half as I was fitting hilos aswell

Quite satisfying aswell

As Cooperman says

[lrostoke]

<sup>The bit you've circled on the right doesn't come off its part of the donut

Get a lever between the subframe and donut (just to right of that circle) looks like a gap is there, lever out whole lot. Might bend subframe a bit, but will straighten up.

Or like mentioned, get a long chisel on the thin end of the trumpet and break the trumpet, should break fairly easy at the thin end.</sup>

ok thanks for the replys, yeh that pictures not from my car from the guide on here, i meant to circle the bit where it meets the subframe. I tried using a chisel there too but it wont come out and the subframe seems pretty thin/rustyish and i dont want to bend break the subframe there. Ive also tried snapping the trumpet in the middle with a chisel/hammer but it just seems too bounce off. Ive just gone and brought a junior hacksaw and was thinking of trying my luck with that?. and i have tried lubricating/penetrating oil. I dont want too use a grinder as i fear the sparks and petrol tank could = bang. But yeh any thoughts on the hack saw idea?

[lrostoke]

Like said try break it near the knuckle, its thinner there

Long chisel and lump hammer should break

[Binzo94]

ok ill go have another look.

You should be be giving attention to the state of your shell and subframe, both of which would appear to be rusty, before you bother with things like hilos. In particular, the subframe looks to be in rather poor condition, and if rust is rapidly takling hold of the lower edge of the wheel arch, it is likely to be much worse in other vital places.

It's not his mini Tiger :) he found the picture just for illustration purposes

[tiger99]

Oh, thanks for pointing that out. That makes a lot more sense. I have seen a few people pointlessly fitting all manner of goodies to rusty old heaps, which makes me very sad, and I thought that perhaps we had another, so I do apologise.

[Binzo94]

yeh that picture is from the faq section, ive given up for today though, going to try have another go on staurday or sunday after work :)

keep belting the chisel into the gap where the donut and cone meet, if it brakes its no harm and if it separates all the better

[Cooperman]

The way to break a trumpet which is jammed in is to drill a few holes in it at about half-way along its length. Then smash it with a big chisel and club hammer. That'll break it, but make sure you are wearing goggles when you do this.
