I was looking on line yesterday and saw an American chap on Youtube reassembling a Commano 'box and being very careful to set the endfloat on the kickstart shaft at "between 5 and 10 thou" before finally refitting the inner cover. He even fitted a spacer to the shaft to achieve this.
I have both Haynes manuals and an original NVT Workshop Manual and neither refers to any such dimension? I can certainly see the point of controlling the amount of movement on this shaft as its inboard end contains the layshaft bearing - so is this dimension by way of update? It's not clear on the Youtube video whether the gearbox in question has the needle roller layshft bearing mod - which presumably would require some change in set up if only to compensate for the shoulder of the missing bush?

With the original layshaft ball bearing which is prone to failure there is no need to control endfloat as the bearing is an interference fit in the casting and on the layshaft, when you fit the roller bearing upgrade the bearing inner can move in and so you need to control endfloat. As it's an unofficial upgrade no factory manual will cover the requirement. The needle roller instead of the bush in the kickstart shaft on its own should not require the endfloat to be controlled but anyone doing it would also have the roller bearing which will need it.
