Bob,
Are you sitting comfortably ?……..
I have just checked the backlash/play on my 15/6. With the car in 3rd gear and the right wheel on the ground, the left wheel can be rotated per the markings in this picture…
The 75mm is measured at the point at which it is marked, roughly in the middle of the tyrewall. Displacement at the tread is therefore nearer 100mm – apparently much more than yours. Despite that I definitely do not have anything but a smooth, comfortable ride in all gears at all speeds.
Out of curiosity, I also repeated the exercise with 1st gear engaged. That gave a very similar, possibly slightly lower result. I think the small difference could perhaps be attributed to the crude checking system but is probably different gear wear.
My findings lead me to believe your problem is unlikely to be caused by the play in your transmission.
Hope this helps.
