my latest project is a triumph unit 500, its a 1971 model after stripping it back to the bare frame so it can be coated, dismantling the swinging arm is proving to be a headache, the book says take off the end threaded bolts (with grease nipples on) then take the spacers and gaiters off then the arm drops out, not so in my case, once the bolts are taken out the spacers and gaiters will not budge, tapping the arm or trying to prise the spacers -gaiters out dosent seem to move them, and not wanting to damage the arm, gaiters centre spindle etc would like first to ask advise as I am aware at least one member used to look after these bikes on a professional baisis thanks in advance for any much appreciated advice
