[Tigers] Lower fulcrum pin

                My 1st 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.

Subject: [Tigers] Lower fulcrum pin

 

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.

 

Thanks 

Richard
