CED VideoDisc and Player Discussion

[lynx]

For the last few months, I have been researching the methods of repairing my RCA model SFT 100 W CED player online, which I want to do correctly. What I have been doing is watching the CED workshop videos on You Tube, which are very helpful & informative. I took notes while I watched them, and I also wrote a list of the supplies which are needed to repair my player by myself.



Here is a list of the supplies that I have already bought:



- The RCA service manual.

- Servo motor drive belts from Kevin Santry. He also suggested that I clean the servo gears with Q-tips & rubbing alcohol.

- Phil Wood Tenacious Oil.

- WD 40 specialist electrical contact cleaner spray.

I already owned a screwdriver set & a paint brush set before I started working on my player.



Here are the supplies from the list in the video that I don't have yet:

- Silicone grease.

- Light synthetic machine oil.

- Omni Lube 350 oil.

- Digital multimetre set with DC & AC resistance ranges.



Here is my question. I am familiar with how to change the servo drive belt & clean the gears, and I have already lubricated the turntable shaft with Phil Wood Tenacious oil, but I have never used any of the other products before, so I don't know what they are for, or how to use them. Can any one explain their purposes, and also give me some suggestions on how to use them?



I can remember a scene in one of the videos where one of the men uses a thick white grease to lubricate something on the bottom of the player, and then he flipped the function lever up & down several times. There was also another scene where someone sprays a switch on the back of the player, and then he flips it back & forth several times. I can't remember what these fixes were for.



Any help would be much appreciated! Thank you very much!

i haven't seen the vid's you speak of but the heavy grease on the bottom may be the mechanism that raises and lowers the turntable or maybe a dab on the end of the turntable shaft? As for switches probably cleaning the channel 3/4 switch and if there is a switch for the audio track probably spraying that. I'd use deoxit d5 or whatever for the switch cleaning. It's expensive but it seems to be the go to for switch/pot cleaning. I usually take a syringe with a pretty small needle (I got them on ebay) and spray some cleaner in it and then dribble it into the switch where there is an opening,just because it sprays all over everything and then all the excess runs out all over the place. I don't use the plunger part of the syringe just spray a tiny bit in the syringe and then drip a few drops into the switch where there are openings.
I used some stuff designed for guns and fishing reels on the turntable shaft that seems pretty good but it's hard to see it after you apply it. It also leaves a coating that is very abrasion resistant but I switched to a synthetic wheel bearing grease for the turntable shaft. And I mean very little. I lube the bottom "bearing" ever so lightly and then lube the shaft where it rides in the top bearing. Otherwise,doing it any other way (I think) would put lube all over the shaft and that isn't needed/wqould just attract dust and debris. The shaft is just contacting the 2 "bearings" that are about 3/16 thick so lubing the bottom bearing you can slide the shaft in from the top and it doesn't hit any lube until it slides into the bottom bearing and then when it's almost in it's fully installed position the lube at the top of the shaft is hitting/entering the top bearing. Some times I see statemments about something like that type of lube slows down the turntable but I didn't notice that. I could see it with the old type of bearing grease that was very thick,almost like a paste,but this synthetic stuff I have is a little thicker than honey and very slippery stuff. Like put some on a screwdriver blade and you can't hold the screwdriver blade because it slips thru your fingers (almost)
