end float on bronze bush

On my series 2a gearbox, i have replaced the 2 pegs, replaced the old thrust washer with a standard width new one.
I replaced the broken 1 piece bronze bush with a new, 2 piece. Having put it all back together (including that horrible circlip) I have found that the gears have the right end float, but the bronze bush is snug, with no end float apparent.
Is this OK to leave?
If not, why is some end float needed for the bronze bush, given that it turns with the shaft?
I don't have a lathe, so to create any end float, i presume i would have to take it apart again (with the circlip!), and then sand down the bronze bush?

Or i could just leave it as is...

In general.. end float is important because it takes the load off the bearing, it allows for thermal expansion and somewhere for oil to go. A shaft will normally move slightly under load

I would leave it. You have correct end float for the gears each side of the bush.
As you say it turns with the shaft. I doubt you will be working the box hard in high temperatures where some expansion space may be needed.
It is a rather poor design having just a pin to prevent turning unlike the bush on the other end that is splined on the shaft.
