A bit more progress today, fitted the rebuilt brake bands, gearbox cover and steering levers and then struck a problem, when I was dismantling the tractor the one thing that needed extreme force to remove was the gear lever, I had not realised that the threaded part of the lever shaft has been mushroomed by the force of the puller I used to remove the lever off the taper and keyway, try as I might I could not get the nut to fit back on and unfortunately I do not have a 9/16" 20 tpi thread die, I filed at it with a thread file and fortunately I did have some spare nuts so using grinding paste and hacksaw cuts in a spare nut I eventually managed to restore a thread and get the nut back on but that was three hours later!
