[Healeys] Tie Rod End Slotted Nuts

[Michael Salter]

Hi again Charlie,
In your original request you said that the tie rod ends were the originals
for your BN1.
I have checked an NOS BN2 tie rod end and when I measure the 7/16" thread
it is 0.433" (10.98 mm) diameter and the thread is exactly 20 T.P.I. This
is a U.N.F. thread.
A used early BN1 tie rod end thread is 0.435" (11.49 mm) in diameter and
and the thread is exactly 18 T.P.I. This is a B.S.F. thread.
The original tie rod ends on earlier BN1's were an adjustable type wherein
a split pin could be removed and the slotted cap rotated for adjustment.
After car C.# 157624 the tie rod ends were still B.S.F. but changed to a
non-adjustable type wherein the threaded cap was locked by swaging and was
not designed to be adjusted.
If the tie rod ends that you are dealing with are unlike either of these
then they are almost certainly not "original".
If your thread count is 15 T.P.I. it is obviously neither of those and
those tie rod ends probably fall into the "cheapo repo" category and the
thread could be anything that the manufacturer could find.
