Noise in the 3 speed box is usually caused by wear in the layshaft. This in turn alters the mesh of 1st & 2nd gears leading to them wearing too.
Changing the layshaft is not particularly difficult, just needs care. So long as everything goes back the same way that it came out none of the adjustments will be affected.
The long key holding the gears to the shaft is usually broken. Doesn't seem to affect things but probably a good idea to replace it.
We changed the 2nd gear wheels for Andes gears from Andy Bird. The result is excellent.
