Gillette Super Adjustable "under-clocked"

So I received a new Black Beauty in the post today and started giving it a thorough clean because the "last 1/4 turn" was locked. The TTO mechanism was very stiff and creaky with 20+ years of scum and buildup.
Gave it a soak in boiled water from the kettle for about 15 min and the TTO was looser but you could tell the spring was still locked.
Put a few drops of detergent in the mug and refilled from the boiled kettle for a 30 min soak (water was cool when I pulled it out).
No change.
So then I flushed it with rubbing alcohol and sprayed a generous helping of WD-40 down the barrel, in the hole at the bottom, and in the adjustment barrel. This freed up a lot of the mechanism and got rid of the squeak but it also loosened the collet under the adjustment dial so this happened:


Turns out the TTO spring was "locked" because the adjustment dial was "under-clocked", meaning someone in the past had dialed the adjustment beyond the "1" into the nether-region. I figured this out when I saw the silo-doors touching the safety bar on the '1' setting.
So I used these instructions:

1. Lay the razor down so the spring is facing up. (the black/red thing in the rectangle.)

2. Turn the dial to 9.

3. Using a straightened paperclip, press in on the spring above the number nine.

4. While still holding the spring in, now try to turn it past the stop at 9 towards 1.

5. Once the dial is between 9 an 1 you can release the spring and then it should start clicking again once you reach 1.

Click to expand...

Now the adjustment dial & TTO operates smoothly and the spring engages for the "last 1/4 turn" movement.

Yes! Results!

Well done sir, I also bet you enjoy it much more than if you'd received it in working condition in the first place!

You betcha! It's in my rotation for Friday.

Many thanks for the helpful advice. I had bought a 1977 Superadjustable with the adjustment dial jammed. I had freed up the dial but whatever setting I chose the shave stayed the same! Also I didn't have the 1/4 turn to tighten. Chucked the razor in the back of the cupboard but after reading this article I found a paper clip and reset the dial and it works perfectly! Even regained the 1/4 turn to lock. So happy now.

Wow, great to see a 5 year old thread still providing useful information, isn't the internet just wonderful!
