Hi everyone.

I'm in a bit of a bind wth a split pin that cannot be removed...

Have tried: -

penetrating oil

freeze release spray sprayed for prolonged periods

pliers quite alot

grinding the joined end off

pin punch and hammer

also tried drilling through with a small drill bit but my drill bit ended up snapping

It was not possible to twist or grab it at the joined end as this was straight on and big enough to fill the gap in the castellated nut. It is well and truly seized in :(

Here are some pictures

My guess is the best approach now is to try drill the split pin out but not sure what sort or size of drill bit is best. Looking at that thread I wonder if the nut will even come off when I get the split pin out.

Thanks very much in advance for any suggestions

have you tried wiggling the 'split' end of the pin till it snaps off???

either that or get a small chisel and bash it till it flattens

normally they loosen enough to pull them out with pliers when you do that.

Have tried wiggling split end and ends have snapped off but not flush with the track rod end's thread. Would the aim of bashing it with the chisel be to smash the ends in till the nut can be undone?

Would one of those nut splitter things work?

no, bash them flat with a chisel or a screwdriver so it aligns with the hole through the rod end, then you should be able to knock it out with a pin punch

Hi

Have you any way of heating it and the nut.

If you can try and cover the rubber cover of ball joint if you are keeping it or if not get the heat into it .

Once its had the heat get a socket or spanner on the nut and slacken it the split pin will decide its time to go.

Sounds easier assuming it will work given all the effort already put into it all day today

Will take a walk probably to B&Q and get a blow torch. I assume this one for a tenner with up to 1350 degrees c will get it heated to the desired level?

Also I am guessing it's best for me to leave the steering lock off, or should the lock deal with the stress of me trying to rag the nut off?

if you heat it any oil or grease that is on there will spit at you so wear goggles

Undo the nut and allow it to split the split pin off, then just get a Nyloc nut which will be just as good and will be MOT passable (trust me im a tester)

I agree, just remove the nut and bung a nylock on

Just starting to round the nut off :( Going to give it another try in a bit, but starting to think it would have been a good idea to leave the job to a garage. This is probably the most difficult bit and the rest of the job will hopefully be easy.

What penetrating oil were you using? That looks like a job for PlusGas (accept no substitutes).

Have tried: -

Halfords penetrating oil.

3-in-one professional high performance penetrant spray.

Any ideas where to get plusgas from? Tried searching the usual suspects on the internet but no results.

Starting to think it might be a good idea to admit defeat, tighten everything back up and call around some local garages to ask if they can just take the nuts off and bung some nylocs on. There's some back street garages not far in some under railway lock-ups, one has a sign saying Lada specialist

I got mine in the local ironmonger (not part of a chain). Which is an answer, but I'm not sure it's much help!!

Plus gas

As recommened by Ken

Try your local motor spares place thats where I got mine

HTH

Or try diesel. Works absolute wonders!

Blow torch on full for 5 minutes did the trick, saw it smoking and it made some crackling noises which I think must have been the rust giving way. Note to self: after heating a nut with a blow torch and undoing it with a spanner, do not touch end of spanner

Thanks for all the suggestions guys, will have to grab myself a can of plusgas when I can find it for future use. Just the other side to do now - and have the M12 nylocs ordered

Ive been in the trade now for over 25 years , and have tried every concievable type of penetrating oil, WD40 and duck oil have proved to be the best, but if you get stuck coke cola will do the job as well, as long as it isnt flat
