Does anyone have any tips on loosening the inlet housing nut on a JD? I have removed the set screw and have soaked the area of the inlet housing threads for a few days with Penetrating fluid. I don't have the special spanner wrench and since the nuts are already pretty badly buggered from previous pinch use (and since replacements are available) I tried loosening them with a punch. They didn't move and I was afraid to smack them too hard so I soaked them a few more days. Today I heated the area with a propane torch and tried the loosen them again but still no go. Again I hesitate to smack it too hard for fear of breaking the cylinders.
The set up I'm using:
1. I have the cylinder clamped into a vise holding the mounting flange between hard wood lined vise jaws.
2. I'm assuming the nut is right hand thread.
3. I'm assuming there is only one set screw per cylinder.
