I would be more worried about a worn out washer E76,
If the Nut has been loose the washer spins and wears out,
Letting 4 th gear not to be in full mesh with the double gear,
We did Terry Wordinghams and found just a tiny ring , In stead of a washer,
The ring was so hard to see, Somebody fitted a new E76,
But the Bike was not run till we got hold of it !,
Which took all the free play out of the main shaft,
Lucky I always give the shaft a push pull , And found NO play !, So we stripped it out.
Love posting Trev's gearbox photo !.
