Just wondering what is the best type of lubrication to use.
- The screw drive for the tone arm. Do you degrease it and then apply new?
- The Spindle: I did not see an easy way to get to it.
Any other areas that need lubrication?
Appreciate the name of the best lubricants to use.
I figured out how to get the spindle off. It has a lever which moves the sensor out of the way.
The shaft was so dry that it would not spin by hand for more than 1 rotation. I put some 3 in 1 oil on the shaft and in the hole. Now it spins like a new bike tire.
I would say most 20 + year old beograms probably need that lubed up.
Not sure what type of grease to use on the worm gear though.
Make sure you clean off the 3in1, and apply some decent sewing machine oil, or Liquid Bearings, where grease is needed use Silicone Grease, or at least Liquid Bearings.
Collecting Vintage B&O is not a hobby, its a lifestyle.
Yes, 3 in 1 is bad news. Too acid. Singer oil will be fine.
Jacques
Really 3 in 1 is bad for metal parts?
I have read these have been used by people. Phone Lube probably the safe bet since its been tested on phonos.
singer oil,
Mobile 1 car oil synth,
Turbine oil - eats up rubber though.
Liquid bearing
Phono lube
Horrible stuff - not as bad as WD40 but best avoided for this application.
Liquid Bearings is great stuff as it doesn't dry out at all. The Singer sewing machine oil is a good second.
Dave.
And Mobil 1 for turntable bearing is often recommended.
Thanks for the heads up on the 3 in 1.
WD I use more of a degreaser, it works ok for cleaning up old oil.

One of the 2000 listed uses on forums is believe it or not:
'keeps flies off cows'!
It also apparently polishes floors and stops windscreens from fogging up. Over 2000 uses for it listed. I dread to think what some of them are. It does have its place in the home but not for B&O restoration.
What about the grease for the worm gear?
I read somewhere a guy used the wrong stuff and it gummed it up. Trying to avoid that. Can't find the post on what he used that worked.
Its some kind of grease and not thin sewing machine oil. All I can think of is maybe lithium grease.
Lithium grease is bad for plastics, use Silicone grease
I have used Liquid Bearings and liked it. I have also used various Tri-Flow products and like them too.
Liquid Bearings for the screw gear too? I ordered some for the platter bearing. The screw drive original lube is grease not oil.
On my last BG8002 I worked on, there was some vibration in the movement of the tonearm when it was returning to the stop position. I added some silicone grease to the smooth guide rails and that fixed that problem. For the drive screw, I also used some silicone grease. However, that seemed to cause a problem with the Beogram starting up play...so I removed that grease and just used some Tri-flow liquid lubricant. I haven't had a problem since.
Thanks Sonavar,
I just ordered these off amazon, figured one will work well.
Phono Lubeliquid bearingsZoom Spout Turbine Oilsewing machine oil (mostly because it has a really nice applicator)
Looking around inside the 8002 the areas that might need lube.
- Platter bearing - ill try the turbine oil there
- Rails and screw drive - Either phono lube or maybe liquid bearings. Not sure if they are plastic safe.
- Servo motor that turns the screw drive. ??? no idea
- Solenoid that raises and lowers the tone arm - ???
- tone arm ???
Wondering how the silicon grease altered the function of the screw drive? Too thick?
There may be different grades of this grease, I used it some 2 years ago on my TX2 on the rails and the screw drive, until now no problems

Could be but I don't really know. I'm sold on Tri-Flow now so that is what I use for that type of lubrication scenario.
I mean what made you remove it? What did it start to do. Or was it fine and you just wanted to try triflo.
Which Tri-Flow product? They make a bunch.
This one?

On that particular Beogram 8002, as I was wrapping up the restoration, I started to see the start play function was intermittently not going all the way to the record and setting down. The tonearm was stalling out and stopping halfway to the platter. Martin told me to check the grease on the on the worm gear and replace it with something lighter. He also suggested I perform the "Manual << and > >>" adjustment procedure in the service manual. I did both things and the problem went away.
Martin's theory on the grease being a factor is that the tonearm uses a lower voltage to move it the last 4-5 mm of travel up to the lead-in groove. So the wrong lubricant could be a factor in interfering with that travel. Sounds reasonable to me and the new lubricant worked.
I do have the two Tri-Flow items you list in your post above. However, the Tri-Flo lubricant I used on the Beogram worm gear is the TF0021060 Superior Lubricant in the drip bottle - here. I also have that in the spray can version.
However, you said you ordered a bottle of Liquid Bearings. That will also do an excellent job.
Thanks Sonavor, well apparently I don't know much about oils so appreciate the information. I used 3 in 1 small motor oil thinking that was fine and then have been since told it was not a smart move on my part.
Here is the Oil roundup. I plan to do a full lab analysis on each and every one of them. No J/K :)
But I am testing them on the nylon/teflon? gear on my parts machine. The greases Triflow and Phono Lube might be a bit thick, they seem to cause some binding. The Liquid bearing has not arrived yet. The Zoom Spout applicator wins hands down as being the best, can get it into very tight places. I'm just turning the gear and feeling how much resistance is on the gear by feel. So far the zoom sewing and Triflow thin lubes are close.
The lube seems to be more applicable to a large gear which is not in a 8002. Also used the Phono lube on the bearing then cleaned it out and put the Zoom oil in. More friction with the phono lube in terms of how long it would continue to spin by hand. As far as breaking down plastic, I don't think the plastic in the Beogram is the type that breaks down with petroleum. The oils they suggested are petroleum based.
Winner - Zoom Spout sewing machine oil. It has little smell as opposed to tri flow, easier to apply and worked on both the worm gear and bearing and seems to collect less dust.
Actually any of the products below will work. Liquid bearing would be close second, then turbine, then triflow and 3 in 1 last. But even 3 in 1 blue bottle worked. The 3 in 1 on a motor fan seemed to loose its lube maybe dried out in a few days vs the sewing machine oil which was easier to apply and seems to last much longer without breakdown.
Wondering how much oil people typically add to the main bearing well, assuming any old oil has been cleaned out first. I
When I restore the Beogram 8000 and 8002 turntables I always clean off all the old grease and oil. Especially the tonearm drive shaft and I clean out the drive bearing well along with the bearing. The bearing well is some sort of nylon plastic. I don't usually grease or oil it as the bearing isn't supposed to rotate around in it. The plastic housing is bolted to the arm assembly and as the drive shaft turns the bearing moves taking the arm assembly with it. You don't want to over oil the drive shaft where oil drips everywhere as the shaft rotates. As it is, any excess oil will collect in the bearing well.
-sonavor
You don't add oil to the bearing for the hub that's underneath the sub platter? I haven't had my 8002 open in a while, but I thought this required lubrication.
Sorry, the previous posts were all about the tonearm drive shaft lubrication so I thought that is what you were inquiring about. For the main shaft bearing all that is required is a small amount to the end, the shaft point and some streaks of oil along the spindle shaft.-sonavor
Yep, I figured that there was a misunderstanding. Thanks for telling me what works for you re lubricating the main shaft bearing.
