Just fitting a new layshaft into a gearbox and noticed that the gear cluster bearing track is sat about 2mm above the casings, the steel shim underneath it has some movement as well- it this ok or does it need to be pushed into the cases more? the gearbox/engine ran fine before so shall I just leave it as is? thanks Paul

Remember, when you tighten the centre nut in the clutch, the Xmas tree is pulled away from this bearing, so it might make no difference at all to leave it as it is.

When you stripped it down, was your cluster gear fitted with the 30 x 16 x 1mm bearing retainer shim?
Normally the bearing here is a 16 x 22 x 12. I've seen it where the bearing has been substituted with a 16 x 22 x 14. resulting in the omission of the bearing retainer shim.
