I'm attempting my first restoration of a Snorkel an I have managed to damage the sac guard - perhaps terminally. I picked up the pen quite cheaply, so it's no great drama if I've ruined it, but I'd still like to get it working if I can.
The guard is of the variety which is pinched in all the way around the hard rubber plug. I got the sac out cleanly through the hole in the end of the guard, and proceeded to heat the guard around the plug and try to push the plug out. In the process, my push rod slipped between the guard and plug and out through the end a couple of times, and I think this was the cause of one of my problems.
Firstly, two of the raised ribs of the guard which key into the section are split along their edges for about 1/3 their length (from the open end)- the photo shows the location. The other two ribs appear undamaged. The guard still slides into the section easily enough, but it's not as smooth as it was. It feels quite secure once it's seated.
Secondly, the plug is now quite easy to slide into the guard, certainly much easier that it was to get out. I've re-heated the plug and it seems to have largely returned to the right shape.
Do either or both these issues mean that my pen is toast? For what it's worth, the snorkel tube is still a tight fit in the plug, and the operation of the snorkel extension knob seems smooth enough in the re-assembled pen without the plug and snorkel tube.
Thanks in advance
