Hi all,

I've just sheared the shear pin for the X power feed on my Gorton 8D.
Obviously, I'd like to replace it. I haven't pulled it out yet, but was
wondering if anyone knew what material this is likely to be. I'm assuming I
can just order a length of whatever it is and cut to size, without ordering
the Gorton 8D unobtanium shearing pin at $49.95...

Regards,

Peter

I agree with Gerry in London(just abit west of me).. my JD140 uses Grade 5
bolts for the shear pin( yes, I found out the hard way....ugh).
Number 2 is too soft and may just fold over causing all sorts of
grief..number 8 is way too hard and 'other' things will break before the
bolt does.

Would it be wise to spark-test the old one on a grinder to at least
get an idea of the pin's composition? Doesn't tell the whole story,
but would that be useful?

Sheer pins are made of what ever will bear the load but still sheer off
when things go wrong.

Brass, mild steel, aluminum. Whatever you have handy.

(I still have a few brass pins with too much taper, too much chatter,
the usual first year student errors when turning small things down.)
