Finally got the frozen nut off the bolt yesterday. Didn't have to use the hacksaw.
Apparently enough 0f the liquid wrench stuff had soaked in, and when I tried it Friday morning with the wrench / vise grips and screwdriver I was able to get the nut off and the tank dismounted.
Got the bowl out easily, and started pulling the old sheet vinyl and thats all coming along well.
Still thinking about the tank bolts though.
Nowadays, almost all toilet seat attachment hardware is the nylon bolt type.
Why not nylon bolts / nuts for the tank / bowl attachent?
When I was at Ace Thursday afternoon picking up a new wax ring for bowl re installation, I looked for nylon tank attachment hardware figuring that I'd have to replace the nut / bolt I thought I was going to have to saw through. No such animal. Only brass tank attachment stuff. I didn't think to ask the guy at Ace, who is usually pretty knowledgable. I picked up a set of brass hardware, which I will eventually have to return.
Anybody know why apparently no nylon tank bolt attachment hardware?
Second issue: I'm cleaning up the bolt threads in a wire wheel in the drill press. All nice and clean now. Really interesting aglommeration of green, blue, white and all shades in between of corrosion and crud now gone. It was concentrated where the nut was on the bolt, and below the nut.
Any thoughts on a lube or thread proctectant for the bolt threads before reassembling things so I don't run into this issue again?
(Yeah, I know, if its another 37 years on this specific toilet, it will be someone elses problem, not mine.)
But is there a reason not to use a simple lube like white lithium grease or even vaseline on the brass threads on the bolt and inside the nut?
Thanks.
