<DIV> I never received the original email with your picture so I can’t
comment to what it shows. That said my understand is there are two points
of failure. One at the point where the pin pinches in and the thickness narrows
for the clamping bolts. The other is as Ron stated where the pin curves/tapers.
Apparently not only a point of weakness, if the nuts work loose the curved
washers rubs on the pin, work hardens them, and thus increases the likelihood of
failure. Last I knew the best fix is to purchase the non-rubber
(Urethane???) bushings, remove the center steel insert and use a pin that much
thicker. There are (at least were) a number of people who made the oversized
pins. Given the rarity of a Mark II and the associated value it might be
money well spent to consider that upgrade.</DIV>

My 1<SUP>st</SUP> guess would be that those marks are from a jack stand.
I’m not totally familiar with where the stress cracks occur but I believe they
form where the square bar is turned to round. Machining marks are
generally where stress risers occur and a crack will start.<o:p></o:p></P>

<P class=MsoNormal>While cleaning under the Tiger today I noticed a mark on the
center of the left lower fulcrum pin. After I sanded off the paint
the marks in the attached picture appeared. They are not as deep as they
appear in the picture. There a couple on the right side but not
nearly as much as on the left. They kind of look like they were made
by something holding the pin at installation? They don’t appear to
be stress cracks, but knowing the history of fulcrum pins failing, I would
appreciate the expertise of the List. The car is a 67 Tiger MKII, speedo
showing 42000 miles, don’t know if they are original.<o:p></o:p></P>
