Shut-off solenoid help please!!!

[slowmoe]

I have read the appropriate threads and in in the midst of attempting the replacement off my shut off valve. It has been recommended to remove the electrical conection and ALDA in order to achieve clearence for the removal of the difficult nut.

Thanks CJ and psfred for the great thread: "Fixing '91 300D Shut-off solenoid: how tricky"

My problem: the retaining nut for ALDA has been consistently very difficult to move. It has not, like most nuts, become progresively easier with each turn. I feel like I am stripping something. Is this normal? Secondly, does the base of the electrical conection come off, how? If I can completely remove this, I might be able to get my 10mm socket elbow in there. Any help is appreciated. Thanks in advance.

MB recommends removal of the intake to remove the shut-off diaphram, removal of the boost/altitude compensator IS not recommended by MB OR Bosch.

Yes some do remove IT, but you have found why it isn't recommended.
