Moentrol Cartridge Removal
Installing a Moen 3570 valve.
I seem to remember from somewhere that you should remove internal parts from a tub/shower valve before putting a torch to it, but I can't figure out how the cartridge comes out. Is there an alternative to trying to find the Moen 104421 special tool?
It looks different from my other special tool
I got my 30 years old cartridge removed with Kano Kroil Penetrating oil and CRL
I had the same problem with a Grohe cartridge which was never removed (over 30 years). I first put CRL Calicum Lime remover on a rag and covered it with the plastic bag and a rubber band to hold it for one week.

It really works - there is regular Kroil Penetrating Oil Spray or Kroil Penetrating Oil Spray with Silicone (which may affect the rubber gaskets so you might want to go with the regular spray without silicone). I sprayed is several times through the week and let it just sit there with the penetrating oil on it. And it worked to remove the 30 years old Grohe cartridge that was stuck!
P.S. You can't buy the Kroil Penetrating oil spray the stores but only on-line. The airplane mechanics swear by this penetrating oil spray!:)

I had planned to mainly use a drill until I get what I need without hitting the side or back wall of the valve. Or, I will find a solvent that will melt it.
Here's what I had asked elsewhere, and why:
The brass shaft actually BROKE OFF the other day when using it normally!! I not only have to replace it, but I also have to figure out how to get it out WITHOUT ANY shaft to pull on. So any advice would be very helpful.
I'm planning to do a lot of drilling to get the old one out, and may leave the water on to see if before I drill deep, pressure would force it out. [ When drilling, I won't hit the sides of the valve body itself. I've replaced two other "normal 1222's" before, so I know to burnish and clean the body before inserting the new one. ]
AFTER I drill and get the inner parts out, I'm sure that I'll be left with the plastic shell. HOW do I get that out without destroying the sides of the brass body? Right now, I'm thinking "acetone" or even methyl alcohol. Any ideas out there??
Awaiting your wisdom.... I have two shower heads, so I'm waiting until my new Moen part comes from E.B.
