PregoRoll Posted April 3, 2023 Posted April 3, 2023 Hey Everyone, I need some assistance with getting this hardened steel pin out of this part. The black spacer needs to be able to move up and down the threads, it seems I will only win with Spark Erosion as its hardened and unable to be drilled out. So far I haven't managed to find someone in Joburg who is willing or able to do it. Does anyone know of somebody who could assist? Thanks in advance!
Meezo Posted April 3, 2023 Posted April 3, 2023 i had something similar on the a charge damper which has a no head bolt pushed into it, i had RBC drill it out and push a new pin in for me... not saying he can help in this case, but might be worth asking PregoRoll 1

My advice would be to drill a small hole from the other side and knock it out, but if it was a screw that was cut off, you would need to heat it up, to red hot, drill a hole for an easy out.

I wish I could do that Where the pin is, used to be a grub screw that prevented the black piece from moving on the threads. It seems the only way is drilling or sparking it out.

You should be able to drill it out, Grub screws of that size is normally Gr10.9 and can be drilled with some hassle, you can sharpen a Concrete drill-bit to have a proper cutting edge or heat up the grub screw with an Oxy/acetelene-torch

In which case it is worth trying to cut a slot with a dremel for a screw driver ..... Theunissa, DieselnDust and Mtree 3

If heat and spook piss doesn't do it - maybe spark erosion? But, as noted, check for hidden retainer pins or similar. ChrisF 1

It seems spark erosion is the only way, but struggling to find someone who can do it
LongDonkey Posted April 4, 2023 Posted April 4, 2023 Make a new one........ I had access to a spark eroder 5 yrs back but alas no more. Might be easier to machine a new assembly
Chadvdw67 Posted April 4, 2023 Posted April 4, 2023 Will DM you a number of a guy with a spark eroder, just be warned, it wont be cheap PregoRoll 1

DieselnDust Posted April 4, 2023 Posted April 4, 2023 If a lvl rub screw was in there originally then I would bet ChrisF is on starboard tack. I doubt a pin would have been pressed into a thread. If it was forget about getting it out without spark erosion and a bigger hole at the end. Then you have real problems.
The Ouzo Posted April 4, 2023 Posted April 4, 2023 (edited) what am I missing here, why cant this be drilled out ? Edit: Never mind, I re-read the first post. Edited April 4, 2023 by The Ouzo
Dexter-morgan Posted April 4, 2023 Posted April 4, 2023 Looking at the assembly, it does not look very complex, maybe having a complete new one made will be easier and cheaper, I have a few engineering companies on my company vendor list, send me a DM, I will send you a few numbers, depending on where you are. dasilvarsa and DieselnDust 2
