1976 MZ ISDT replica

 the swing arm is held in place by two 20mm threaded pins, you can't use a traditional swinging arm spindle because the shaft drive runs through it, hence the two pins held in place after adjusting the bearings by two 27mm nuts, the box spanner eventually turned up at work today, as soon as i got in from my shift i tried to slacken the lock nuts off, no chance, sprayed them with a release spray and walked the dog's to give it a chance to work, tried again to see if we had any 'solvent majik', nothing, gas bottle out and  warm them up, try again, the box spanner is deforming with the effort, get the drill out, centre drill in to mark the nut and give a lead in, hit it with a punch and success, same with the other side, wind the nuts off and drop an allen key into the adjuster's to remove the pins, bang, swingarm is free at last, serves me right i suppose, i took it for granted that the bike had come apart ok up to this stage, not suprising with hindsight, the bike's 30 years old and had 15 previous owners, my luck was going to run out sometime, that was tonight......
