Unimatic experts, Last week I started the restoring of my Frigidaires Unimatic WO-65, but I've found the first issue that made me stop and ask for your help.

Trying to remove the pulsator, the pulsator nut that looks like a cone with legs was very easy to be removed using an ordinary wrench and some WD40 but right under it, i've found this (look the picture) and I couldn't understand exactly what's that tiny "C" ring.

I don't know if it's another nut that is screwed above the polsator or if it's part of the pulsator or if it's a clip.

Could you please tell me how to remove it?

By the way, I'm spraying WD40 on it several times a day to maybe help until i know if I should turn it (unscrew), turn the whole rubber ring or just push this ring to the side or maybe cut it and remake the screw.

There is no other nut there, the pulsator will lift off now, but sometimes they get stuck. You need to employ a rocking motion to get it to loosen.
 
Thanks Robert!

It worked!

:D

Tonight I'm going to continue the job. Right under it there was another rubber part that looks like a cup and it also came out easily.

Now there's some kind of coil but I couldn't indetify it clearly yet because it's covered with some kind of black grease residue.

I'll clean it tonight to have a better view and check the reoperation manual to see what to do next.

Now it's sure I need a new pulsator rubber. Now I can see it's severely damaged. That little rubber cup seems to be a little worn, but I think it can be reused.
 
Update Dec 21 before sleep

Guys, if you don't mind, I'm going to use this thread as some kind of blog to post the pictures of the restoration. It can be useful to the guys that are helping me.

Thanks for all the guys that contacted me by Yahoo messenger, Skype, MSN and email.

Your help wouldn't come in better time. It was the best Christmas gift one could give me. Thank you, thank you!

Here goes some pictures I took tonight, after a quick clean using paper towels. I'm going to post the pictures sequentially.

>>>>> pulsator nut. This part is in regular condition. lots of residue inside it and one of it's "legs" is damaged. Can I use it the way it is?

the rubber bellows you see....

are your Water Bellows and Oil Bellows respectively (in order of the display of the pictures. The Water Bellows stretches over the flange of the tub and is secured to the flange by the circular locking ring. Beneath the Water Bellows is your Oil Bellows. This secures to the tub nut by a smaller locking ring. You will most definately need to replace both bellows. You will also need the locking ring tool to remove and install the rings easily. If you don't have one, you can use a small C-Clamp to gently compress the ring so it unlocks. Be careful when you are using the C-Clamp on the Water Bellows as not to crush the flange on the tub. I modified my clamp by grinding a small notch in each end of the clamp so the ring wouldn't slip out (see picture)

I'm sure you will want to remove the tub then....

so you will most likely need a 1 1/2 inch box wrench. The problem here is getting one that will fit in the tub. I went to Sears and bought one and used an angle grinder to cut it down to size (again see picture). Gently with a mallet tap the wrench counter-clockwise and the nut should come free.

Hope this helps buddy.
