A few days ago Randall suggested the answer  could be found in
http://www.vintagetriumphregister.org/maintain/TransRebuild/OverDriveA02.pdf.

As usual Randall is absolutely right. I adjusted the lever using the Haynes 
rcommendation with the 3/16" lock piece and as it said in the VTR write up 
my O/D did'nt work.So to plan B in the write up.However it occurred to me 
that not everyone will have a dial gauge (including me) to measure the "up" 
movement of the ball.
So I used a drill bit of the diameter to fit the top plug hole with marker 
pen ink and marked the "down" position of the ball on the drill. Then on 
energising the solenoid and playing with the pinch bolt I was able to get 
the .030" to .040" lift and confirm it by marking the "up" position of the 
ball. You can measure the distance between the two marks with feelers.
And praise be my O/D works again!

YMMV of course,
