In my eyes - well, obviously - the G 35 looked very pointy , maybe grind it for a bigger radius at the top and polish. Also the spring could be a bit softer and still sufficient camplate positioning in all gears. The spring can be changed any time in case later when getting inside the primary. I did a mod with a lever locking design, no plunger type which gets high side load when changing gear and so no smooth action.
As to the bush in the output shaft: This is very critical to be a nice fit, max. 2 thou play with G 3 . I tried to find the logic of how this gets lubrication, added some more grooves and holes. As far as I know there are suggestions made about mods in this respect but I don´t know . Anybody ? The output bearing is meant to be light press fit on the shaft, like anywhere else for ball bearings or so. So press it up the shaft like before and it should be allright. The output shaft with bearing can then be dropped in the hot case , - provided no staking was done before around the bearing bore .
