undoin seized stuff

[rybes]

afternoon  has anyone got a garunteed way of removoin seized up stuff ? im tryin to undo the spring collar on me tiger shock. thing is its proper seized on. ive soaked it in wd40 for a week, no joy i used 2 foot long stillsons and a breaker bar makin it over 4 foot, no joy. i did think heat but as its steel over ally n ally expands faster than steel i see it causin me more probs. anyone got any ideas cos ive run mine out.

thanks :D

1.  WD40 is a waste of time in seized stuff.   PB Blaster or other products purposfully made for siezed items is far better.
2. HEAT.  Hand held torch to heat it up good often helps.

Would think that this scenario is often entered into by somewhat novice folk that there will be plenty of general info on the Net about it.  Try searching internet for "seized bolt removal".  Might get you alot of info.

Acetone and ATF (automatic transmission fluid) mixed at 50/50.  Without a doubt the BEST seized bolt remover I've every used.  There was actually a scientific test conducted comparing it to many popular commercial products and "the mix" was shown significantly better.  Cheap, so no harm in trying.  Then heat...although I'd avoid a torch, if possible a heat gun is a much safer solution that works just as well in most cases.

cheers for your replys :D its not a bolt i want to remove. ive got all those out. its the big round preload adjuster. the bit you turn with a c spanner.  i wasnt sure if there was a big socket lookin thingy availible to do the job with. im off out in the garage to have a try at movin it today. ill let ya know how i get on

Mr Rybes, You realise there are two nuts there not just the one?
They are locked together, so you might be trying to undo both at the same time?
A hammer and drift usually does the job.  :)

yeah i got one off Mr Rf its just the last one i cant get off. its now in the freezer gunna see if i can shrink the ally enuff it breaks the corrosion. heat dint seem t work.

managed to get it off. heated it up n hit it a few times nuffin happend. froze n heated it up quick n nuffin happened. hit it nuffin happened. so i thought i wonder. put it on its end and in the top of the threads around the nut thing i put some cuttin fluid. heated up the nut thing from underneath till the oil boild n hey presto it disapered. after a few times is made its way thro  jus a shame it ripped up the threads on the way off. still never mind got the chance to try a trick id been waitin years t try. put some fine grindin paste all over the threads on the shock and ion the nut thing and wound it all the way t the bottom then off again. cleaned off the grindin paste an daa daaaah it works how it should

Glad to hear its sorted.  :)

The grinding paste on threads trick we used in the machine tool trade for years.  But it needs extreme care because did you know just how badly it can go wrong?  It only takes one grain of paste to pick up, roll up a bit of metal and you have a snowball effect.  Whichever way you turn it, back or forth, the ball just gets bigger until it's jammed tight.  Same happens if you get a bit of swarf left in a new thread. Only solution is then to machine either the male or female away, depending on which is easiest, and replace it.

Sometimes ignorance is bliss eh?  :lol:
