I would do that.

So... the problem is now resolved completely 😁

I went through the whole cleaning process with acetone again (this time also including the felt rings). After I received the new oil that Martin suggested, I did the same oiling of the bearings in vacuum for 24 hours and another 24 hours in the oil without the vacuum.

The result was instant - the turnplate turns to correct speed within seconds. It is incredible how much difference the oil means to the speed. I immediately noticed the difference in the oil. The Mobil Veolcite no 6 oil is very thin and without much colour to it (the SAE30 I used before was much thicker and more brownish).

A huge thanks to all for their help - I have a very clean machine now - especially on the inside :-)

Fantastic.

I learnt something new here!

I guess I've been lucky in my overhauls, using a no-name lightweight synthetic oil.

Enjoy your TT - it's a superb unit - one of my 3 keepers (BG3000, BG4000, BG4002 AC)

Hello

i had this problem with my Beogram....

Cleaned every parts (supposed to be oiled) with white spirit, living parts for a long night swimming 😁

then tried many oils... took me a lot of time, tests, cleanings again etc...

Fistly I tried with Wd40 : runs good but after 2 lp speed became slow

tried sewing machine oil : was slooooooowwwww

tried Vaseline oil : was running really good but after a couple of weeks the oil dried, was kind of cocked...

tried the oil of my motorcycle: 20w40 ... it’s running really good since March 2020...

i guess for sure the sae30 is too greasy for this motor...

looking at your picture I see a spring which is really bent, consequence: you motor may be in direct contact with the turntable, you probably ear an ugly noise when you are close to your turntable... and ear another ugly noise coming from your speakers... you may have to take to that spring.

... next step : ENJOY 😉 🤗

Hi kimvdk,

First of all, congratulation in sorting out your speed problem and facing the re-oiling process.
I have various motor bearings which would need the same care but I'am a little afraid of jumping in it.

Please would you mind deytailling a little bit your way of infusing it and share a picture of your vaccum setup?
You wrote you used a wine vaccum pump: is it a high end or the little pumps sold for cheap on eBay?

You also wrote about the oven: did you leave the bottle in it turned on, during the the whole 24 hours process?

Thank you for your enlightenments.

Hi Martin,

Can the remaining oil be use again or is it "contaminated" in any way and must be discarded?

And if so: is it possible to treat various bearing in the same vacuum, with the risk of mixing them?
or are they speciffically sized foe each motor?

Last question: I often see large bottle, half filled with very little bearing inside. Is it necessary to use that much oil or just a bit more than needed to drawn the pearls is enough?

Thank you.

Menahem - thanks. I really appreciate the TT. It was my fathers when new, and he recently gave it to me when it had stood still for 20+ years of no use. It means a lot to me as I can remember it from my early childhood (where I accidently broke the stylus at an age of 3 years :)

Guillaume - yeah, the TT is definitely very senitive to the oil being used. Thanks for pointing out the bent spring. I already fixed it. Actually, after the last oiling process and reassembling the TT is a little bit noisy when I put my ear close to it. I might have to take a look again if anything is slightly off spec

- matador43 - actually it was not that hard. When I did the disassembling the first time, I was a bit nervous. But I followed Saint Beogrowlers thread:

My Beogram was new when my father bought it... it stayed 25 to 30 years, out of order... as you.

same story !!!

i am really in love with it... souvenir of my dad...

if still noisy but running good, if you look at the back of the motor (where bottom bearing is fixed), you will see that the center of this part is kind of cut (not on all motors version), you can bent (really little) by pushing or pulling to get the perfect final alignment of the rotor. (No need to tear down your turntable, just do it when running from the bottom... make sure you do not touch the rotor)

anothrer possibility: sometimes a part of the stator is moving a little bit (really close of the rotor), but it would make a bigger noise than what you describe.

Thank you kimvdk for the details.

Just one thing to be sure as I'm not English: "release the vacuum" is opening the bottle and let the air flow in, right?

It's funny how this old vintage gear is freshened up and played again. They are so beatutiful and the sound is... good, natural and "just right" and different from the perfect sound from todays cd's/music streaming.

I will definitely have a look at the motor again. I disassembled the TT/motor many times. Sometimes the noise was there - sometimes it was not, so it probably has to do with some misalignment. Thanks for the tip!

-matador43. Yes, but releasing the vacuum I just mean to let the air flow in while the bearings are still in the oil. The oil is then supposed to be "sucked" into the bearings. Just leave it in the oil for 24 hours.
