So left confused by the fact that the valve was soldered to the tube on the first Rochester, I disassembled the other 4 rifles…
Rochester #2. This is the 2nd best one.
The butt stock is actually in better shape.
Missing screws in the barrel band though.
And those are unlike the screws used in the other ones.
Roll pin instead of a solid pin.
Different pump head. Just a little grease…
The nut that retains the hammer spring is different.
Nut, spring and hammer sleeve.
All the other Rochesters had this type of nut, and only one nut.
The valve on this one is soldered to the tube as well.
You can see the smearing of solder on the brass.
So I took apart another Rochester, #3. It’s also soldered but has a brass ring as well. Not sure why.
The 4th valve wasn’t soldered, as far as I could tell. However mechanical means would not unscrew it. It seems to have a cement-like substance between the halves. Probably need heat anyway.
And the fifth valve is soldered to the tube.
Here’s the valve from Rochester #1 again, just so the valves are all on one page.
So four out of five valve assemblies are soldered to the tube. Next up it to make a vise block that snugly fits the valve body and a wrench that fits the tube (somewhat like a barrel vise and wrench), then use a propane torch to heat up the join and see if I can unscrew the halves. Sounds like fun…
