Upon thinking about my problem, this message contains a hint at the only
explanation that makes sense to me....
I must not have had the lifting bracket tight enough on the rocker shaft.
I've done this engine pull several times, and I know that it is important to
tighten the bracket...
But, this time, I must have just not had it on tight enough.....there must
have been some sort of slop that allowed a bending-shear force to get
applied.
That is the only explanation that I can come up with...
BTW... the rocker pedestals are all fine... it was only the stud that broke
off ---
Thanks

PS...there always has to be a rational explanation...even if it sometimes is
"pilot error"

In reply to the question if anyone else has had this happen, then no, we
have not. However we always tighten the lifting bracket down onto the top
of the nut holding the rockershaft. That way there is no slop and no area
for bending/shearing. The lifting capacity of the studs is probably many
times the weight of the power unit.
