...I am trying to change these washers in the pillion footrests. I am trying different procedures but the space is minimal and also I am chipping all the paint. So next possibility, but I am here asking before to do it, is to red heat the spring washer to softened and to massage it inside that cavity... could be a wrong idea?
That would be a dumb idea....you would loose al the coil tension in the washer and then your pillion peg would flop down all the time.
Try spreading your pillion peg fork out a bit.
Use a longer bolt or threaded rod that is small enough to go through the footrest thread without using it and then two thin nuts then turn the nuts out. If you can, use plain washers to protect your paint while you do this. If you don't understand what I am saying get back to me and I will go into more detail.
BTW I have never ever had any problem with this task....so your fork must be bent or the washer is the wrong one or something.
I imagined the possible lose of the tension hence I asked before to do anything...
I think that I understand what you are trying to explain but the peg forks (the hangers) are dead hard impossible to move it to gain space. The springs are new and look thick, I do not have right now the an old one to compare; I only remember that the old one was loose there so there s no right action.
...the space in the hanger peg is 7/16 the other part is 5/16 and the washer is 3/16 without compression; with compression is 5/32 I cannot imagine how the factory did to put these ones without chipping the paint.
Fernando, are you sure that these spring washers are original ? The ones in the footrests of my Triumh look thinner than the one in your picture. I had the same problem as you, that the footrests moved down by itself, and I cured this by fitting a thin steel washer behind the spring washer.

That looks like a standard hardware store spring washer to me--made from fairly thick flat stock. The "proper" spring washer is made from much thinner flat stock and consequently fits quite easily into the pillion footrest. In fact as previously mentioned if the footrest itself has worn away/corroded away between the "jaws" of the footrest then you sometimes need to add a plain washer to the spring washer in order to get the right amount of force to stop the pillion footrest flopping down instead of staying in an upright position. So--reverb--get the correct washers----or if that is difficult because of where you live then grind off some of the existing washer---a bit at a time---trying it in the footrest at each stage. HTH
I know you are at the last outpost of civilization but if you have to modify something to make it work it's not the correct part. The part # for that on a 68 is F2277 and it looks kind of like the thackery in the rocker box. By the time you grind down what you have there will nothing left. I'd find a new parts guy.

With the correct thackery washer, ( thinner than shown ) because the late 50s bike used the same part numbers , the way to tighten tension on footpeg it to turn slotted screw in and lock in place with lock nut. Unless thread has been drilled out !
