oh yes -- been a while Dave since I have had one apart
maybe late for this - but - I have my favorite side to work from when taking apart coaster brake hubs
seems that it is the side opposite the brake arm
so -- the cones and such on the brake arm side I do not touch -- they stay tight
if you have everyTHING apart -- might try
putting brake arm side together first with cones and axle
then lay all of your washer THINGS over that
then -- work it slowly back into hub -- from brake arm side
you will get it -- MM
