  There was one list member who knew a professional person associated with 
the problem say, "every pin is subject to failure."  On the other hand there 
are still people out there with their original pins and no apparent intent 
to replace them.  A number of years ago Derek White has some pins made in 
Africa.  They were purported to be made from steel used in Caterpillar 
tractors.  There are other, more local vendors now, but I have no experience 
with them.  Others on the list will be better able to advise you.

 There are bushings available that have a removable center section.  The 
current set up is to remove the bushing, use an oversize fulcrum pin and 
gain the added strength.  Again, there are others here who can provide the 
links.  Also, there are reinforcements to the crossmember that externally 
support the pin and help to prevent stress. So, yes, there has been progress 
in the matter.

 That said my understanding is that "some" of the failures occur because the 
bushings loosen and the washers turn and work harden the pin. So, at a 
minimum I would check that.
