I take the shaft and spur out of the gearbox, slip the shaft between the jaws of a vice (just open enough to allow the shaft between) so that the spur rests flat on the top of the vice. Tap lightly on the 'front' end of the shaft and gently drive it down through the spur. Fit the new spur by placing it, front face down, on the top of the vice and tap the shaft through from the rear.
