I did promise sometime ago to provide an update on a gear change issue I was having. It began with losing first gear on my 67 Bonneville. No amount of prodding pushing or pulling would engage first gear. Praying to the shrine of Saint Turner that it wasn't a fault inside the inner workings I pulled off the outer gearbox cover. My prayers were answered as it transpired to simply be one of the two quadrant springs that had broken. Easily and cheaply replaced first gear was once more easily selected. Then the dreaded BUT, I immediately discovered fourth gear had become somewhat shy. It took two or even three goes to engage fourth gear every gear change! I was 99.9% convinced it wasn't a coincidence and was somehow connected to the previous problem. I also decided to live with it for awhile but a painful right toe eventually led to a second peek inside Turners wonderful world of cogs. As a matter of course I replaced all the bearings accessible in just the outer cover including seals although they were fine. A long hard look at the new springs revealed two points. The new springs are a fair bit shorter than the originals plus the quadrant thingy was not entirely centralised when at rest. I concluded that this lack of being in the exact middle position (it wasn't by very much at all) might be enough to limit the amount of travel required to engage fourth gear. I inserted a couple of washers at one end of the spring to centralise the quadrant thingy and voila! on assembly I now had fourth gear with just a snick of the gear lever and a toe that is much happier. Although the new springs were shorter I don't believe this was a problem, it was simply the imbalance between them. Packing one with washers was the cure.

I hope those washers can't find their way loose...
