Akronman every time you post pics of the innards
of that magnificent SQ, it makes me smile.
I can't offer any advice on what you plan to do (I have a late model unit totally different that yours).
But I must say, the shot of that famous Arc-Cuate transmission, proven in millions of installations, really made my day.
I marveled at the shots of large, sturdy, bolts holding the works together.
I gushed with pride when I saw nice solid steel (or aluminum) making up the components.
Your machine is living testimony to a long forgotten time of when made in USA really meant something. When quality, not shareholder value, was the name of the game.
Long before Americans became sheeple, value was not perceived as to what is the cheapest, but what gave you the longest use.
I mean really, you stated this machine is 40 years old correct? I will bet a box of Sears detergent that NO machine made today, regardless of it being TL or FL made here or in Timbuktu, will last 40 years. I challenge anyone on this forum to prove me wrong (of course I will be well into my 80's and probably in an old folks home).
Can't recall which thread or where, but someone posted a pic of the spider assembly from an LG or Samsung. It was a whopping 2 years old and looked like some scrap metal from Hiroshima or something.
Or the mode shifters that crap out on shareholder value driven GE TL machines. Or the legion of bearing failures in Whirltags. Or any FL with the fancy dancy electronics that blow up, short out, or have to be "rebooted".
Congrats again on finding this machine and kudos to you for your willingness to use some elbow grease in keeping it in tip top condition.
