you shouldn't be tightening the wheel bearings...Just hand tighten and put the cotter pin in

Must be something very wrong with either the hub - or the axle stub shaft. As above - the nut doesn't want to be very tight, although it should be 'tight' - and then put the split pin in. I suggest you try another hub - and is that still doesn't work then try another kingpin assembly.

The front hub nut should be tightened to 35/40 lbf ft torque. The bearings are 'angular contact' and are designed to be 'pre-loaded', which is controlled by the spacer between the bearings, not the tightness of the hub nut.

When you fitted the bearings before, could you get any movement in the wheel afterwards? There should not be any, other than it being able to revolve!

Are you sure that you are putting the bearings in the right way round? Even with hard use they should last 10,000 miles, at least.

Correct. Standard Minor wheel bearings are done up to that torque setting. other types are done up loosely as suggested above. When in doubt, RTFM.

I have taken the hub appart again and had look whats happened is that the bearing closes to back plate has moved and causing play in hub, what could this be down to? worth gettin new hub?

If you have the correct size bearings, and the spacers and washers fitted correctly then when the wheel nut is tightened you should, with a slight foward or backward turning of the nut be able to fit the split pin through the hole in the axle. There are usually 2 holes at right angles so choose the hole which is the best fit.
I notice that you say it is the left wheel bearing which is coming loose. The left axle wheel nut has an anti clockwise thread so that as the wheel turns forward it tightens the nut. I assume that the swivel pin is correct and hasn't been fitted with a right hand axle.

the bearing closest to back plate has moved and causing play in hub,

when you say 'moved' what exactly do you mean? When the hub nut is done up I can't see what is going to move, so a bit more info would help.

Most likely event here is that the loose spacer has not been fitted between the bearings. I have NEVER had a hub bearing failure - so don't blame the 'skid turn' etc - i've done plenty of them.
