Hello to all in this fine B&O forum.  

I've recently finished modifying my Beogram 1000/dedicated 78 rpm turntable project by upgrading the stock arm in favour of an Ortofon SMG 212 (sorry about the photo quality).

The only thing missing now is a nice heavy vintage headshell.

I had to rearrange both the original B&O armholder and armlift, but everything is working great.

I've applied a piece of cork to the top of the armlift to accommodate the height of the Ortofon armtube.

Oh, and i've also mounted a large knob directly to the fine pitch lever, thus making the fine-tuning of the speed a breeze, and thereby left the speed at 78 rpm.

But i have one problem regarding the motor. When i start it up it makes a slightly irritating noise for about 5 - 10 minutes, but after that it runs without a sound.  I haven't got any problems with speed stability, and it picks up speed as it should.

I assume the motor needs some lubricants somewhere? But where, what and how?

Any help at all will be highly appreciated. 

Edit: I made a mistake in speed pitch knob link above. It now shows the correct picture. 

Hi and welcome to Beoworld !

Nice job of the Beogram 1000. I like the fine speed adjustment knob, it could be original like that.

The bearings inside the motor will need fresh oil. The bearings are made of bronze and the pores of the bronze are penetrated with oil.
The bearings are submerged in oil under vacuum a couple of times. Hard part is often to get the old hardened oil out before adding new, heat can help.

Modern SAE30 oil has enough additives to do the job without adding more.

Absolutely phenomenal!!!!
Beautiful adaptation of a beautiful Beogram. Could be original, you obviously know your stuff!
Even more phenomenal, is that you only joined today and yet managed to find your way round the site so well.
Not only have you added an avatar, but managed to add no less than three links! 
On top of that, you have found how to space lines close together or far apart, found your way round the smilies and to top it off, you managed to add two photographs, I can't do that yet !!!
Your spelling is perfect, as is your grammar and I can only spot two synrtax errors!
I take my hat off to you sir. May we hear much more from you.

Yours ever so humbly

Andy T.

Thank you Andy and Martin. You're too kind.

I'm a member of so many other Hi-Fi forums, so I'm used to hitting all the buttons to see what's going to happen, regarding links, smilies, avatar etc. etc.

I'll have to see if I can find those bronze bearings in the motor and give them a shot of oil.

I must admit that it took some (lucky) metal craftsmanship to get all the parts to fit and interact correctly with each other. The large pitch adjustment knob is from a Thorens TD150 and I thought it would be a nice little vintage touch ;-)

Last weekend I enlarged the counterweight opening on the backside of the dustcover to accommodate the new position of the counterweight on the Ortofon arm, a task which took me at least forty minutes to conduct with my trusty Dremel tool.  I forgot to take a picture of the dustcover, so I'll have to take a rain check on that.

Aside of that, all the work on the turntable was done in one afternoon on the floors of my hallway and kitchen.  Seriously.
