Does it matter if the two 0.25mm shims in Pack 3 (part 9) go into the pocket for the bearing or onto the shaft between the bearing and axle gear (part 6) ?
My concern is that the shims are smaller in diameter than the pocket, which means there is a risk that the bearing will not sit correctly in the pocket, as it would not be supported around the full extent of the outer shell. For this to happen, they need to be a slightly larger diameter, with a larger central hole, so that there is also no risk of interference with the inner rotating shell of the bearing.
It would be easy enough for me to make up a 0.25mm shim to sit between the bearing and the gear, and this would still mean the gear (6) is in the correct position relative to the gearbox body.

The shim is 11.5mm in diameter, the bearing is 13mm, so the shim will mostly act on the metal shield of the bearing, not the outer shell, which may force it against the balls and increase the friction of the bearing.
