play in bk1204 end bearing blocks

[Clive S]

I think you need to take the bearings out. Make sure they are the right way round ( either facing each other or back to back) and put a shim between the outer rings. I have used a bit of fuse wire one piece put around the face of the bearing then when you put the endplate back on it will tighten the races up when you put the lock nut back on. ..Clive

These are AC bearings and need to be orientated the correct way round the idea to shim them apart is to be able to give a little pre-load. 15A fuse wire is about .6mm and acts like a shim.
I can not take credit for this tip as I have learnt it from higher up the food chain!! ..Clive
