Can you get a tool to remove........

[Andy335Touring]

......these steel dowels that are pressed in to some TB's ?

Some kind of puller or some thing ?

I have drilled and battered to death two dowels so far but it took ages !

[Andy325i]

How about a slide hammer? We used one the other day to get the bush out of the E36 steering joint, worked a treat and didn't damage the bush what so ever

[Andy335Touring]

What,tap a thread in to the dowel and attatch the slide hammer to the tread ?

Just trying to think how you would attach the hammer to the dowel or how the hammer could get a grip of the dowel ?

I don't own or have ever used a slide hammer so i'm a bit clue less

[Andy325i]

can you get "behind" the dowl? Not sure if the slide hammer has an attachment that opens up inside the dowl? Will ask my mate, he will know how to get it out for sure

[Andy335Touring]

No you can't get behind it,if you look at my sig you will see that theres to much stuf in the way to knock the them out from behind.

[Ant]

have you tried cutting through them Andy ? junior hack or coping saw should get in there to do the job, access looks terrible though

once cut through they should fall out

[TOURINGDADDY]

Have u got oxy acettlin or a blow torch.... heat up around the dowel (not the dowel) till glowin then get a firm grip with some moles and then u got ur self a weeeeeeee bit

[Andy335Touring]

Thanks every ones for your help

The first thing i tried was using a jig saw with a metal cutting blade and it hardly scratched it ! After one minuets sawing the blade was worn out,see the picy below.

I used a slowish speed on the jig saw and a drop of oil.

Erm,i'm a bit scared of using heat on them as the TB's are made from Aly.

Theres so little dowel showing that it makes it hard to grip with moleys.

[Sjoerd320i]

isn't it possible to use a figure saw? or isn't there enough room for it?
or maybe a diamant drill? expensive but it will work very good

[Andy335Touring]

Whats a figure saw mate ? I tried to google search it but no joy.

Diamond drill bit would be handy as i've all but blunted my drill bits getting two dowels out.

[Sjoerd320i]

this is a figure saw, at least thats how we call it literaly trasnsated.



you can get loads of different saws for those things

[Andy335Touring]

Ah yeah, thanks, i think i might have one of those some where ?

I'll give it a go,i hope its up to it !

cheers

can u not hit it with a chisel and bend it inwards...?

[Andy335Touring]

can u not hit it with a chisel and bend it inwards...?

I've tried it mate,it just bends the exposed end.I tried to hammer it with a screw driver sort of inbetween the dowel and the hole in which it sits but the dowel is well hard.If i had tried to force it any more i think the TB would have broke by the hole if that make any sence to you.I'm a bit shit at describing stuf some times.

I shall carry on trying to sort it on Monday,i'm off to Rockingham tomorrow to watch the racing !

[Karan]

yeh i get u........... i doubt slide hammer will work either,.... need to press/pull it somehow....

[ian332isport]

How about a couple of sockets, some washers and a nut and bolt.

Get a socket that will fit inside the hole in the alloy casting, and sit on the end of the dowel. Then get a larger socket that is a little larger than the dowel, and put it over the exposed end of the dowel.

Then use a nut and bolt (right through the middle of the sockets and the dowel) and a couple of washers (if needed) to wind the dowel out. Quite often this will shift things much better than trying to bash it out. You could also use the two socket method but clamp it in a big vice to force the dowel out. A bit of gentle heat would also help.

Cheers,

Ian.

[jonbuoy]

They were obviosly pressed in so i reckon your best bet is to bung someone a couple of quid to press them back out. Heat is a great idea if u know what your doin but not always the best way, if u heat to much the alloy will crumble away, if u don't heat it enough u still won't get it out. Unfortunately there is no happy medium, it will cost less to get them pressed out and there won't be any damage or stress to the face. Good luck, will look brilliant when its on.

[Andy335Touring]

I apologise in advance for the shity drawing(and explanation)

The dowel would have been pressed in from the gasket/head side of the TB as the hole that it is pressed into narrows to the same diameter as the inside of the dowel so it carn't be forced out that way.

I don't know weather this very rough drawing will be of help or not !?



I've got a few things i want to try that have been sugested(sp?) after that i want to see if i can tap a tread on the inside of the dowel and screw in some threaded bar in to it so i can make like a home made slide hammer ?

Or to use your idea Ian sort of in reverse to try to make a puller but it all depends if i can tap a thread in to it.

Thanks again for every ones help

[Toby_Unna]

guess you won't get this in time before tomorrow Andy... but if you bring em to me on your way to rockingham i'll weld up the exposed end so you can put something through from the back and bash em out. shouldn't damage the aluminium, i used a similar trick to get a sheared stud outta my cylinderhead and it's been fine since.

[Andy335Touring]

Sounds cool mate ! See you tomorrow morning,time for some shut eye !

[Toby_Unna]

[Quaser]

Try twisting them out with some mole grips, but unsing them sidways on, not from the tip!

[Andy335Touring]

They are all sorted now thanks to Toby

He welded a bolt to each dowel and twisted/pulled them out,worked a treat !

[Toby_Unna]

glad i could help Andy, did it get you to the meet and back ok then?!

got ya pm, going out to try that ecu and coil on mine now, will let u know how it goes... cheers

[Andy335Touring]

Yeah,there and back no probs,just hope i didn't get caught speeding

I hope those bits cure your problem.
