So....
The gear box has some positives and some negatives. It has a Q2
but it whines in 2nd gear
and jumps out of reverse gear
:furious:....
So I started to strip it down not really knowing what I am doing;

So this is reverse gear...

The bolt in the top of the shaft goes through the gear box casing into the shaft, I've just popped it back in for safe keeping... But it does mean that the shaft's position in the box is 'fixed'.

And this is 2nd gear. The box has been rebuilt following the expiration of the standard diff, I suspect that the marks on the gears will be as a result of this but could this be the cause of the whine it has in 2nd only?

Back to reverse. If you move the selector ring to engage reverse, it doesn't lock into position like the other gears do. I don't really understand how it is supposed to work as the other gears use a different mechanism (3 roller bearings with springs behind them that lock into a groove on the inside of the gear).
This is it in it's disengaged state

And engaged...

There's not really anything to it and I can't see anything missing relative to what's on elearn.

But if you prod at it in its disengaged state in the open box there is significant movement in the deeper (thicker) top cog, like something is amiss. (see video below) There is a point where I think the two parts will hold the top cog in a correct position and not allow it to rattle around whilst still not being engaged but I can't see how this would be achieved. There doesn't appear to be any means of adjustment.
Pic below is of of the 2 main shafts in the box, reverse operates as a 3rd gear between the two so that, obviously, one the output shaft turns in the opposite direction...
The shaft at the top of the pic is the input shaft and the one below it is the output. The pinion gear for the crown wheel on the diff is on the thick one on the very left of the output shaft.
