Beogram 3000 type 5228, 5231, 5241. I just installed the new idler wheel from Martin and infused my bearings with oil and took lots of pictures to share. I’ve struggled with this table going too fast or too slow in the past and received lots of help here for which I’m very thankful. I love this thing.

Beogram supported upside down. Not on the switch or the arm of course.

I set this close to the table and left the wires attached.

2 nuts for the motor suspension, the 1 on the right is already removed in the photo. This spring motor suspension works great at isolating the noise from the powerful motor and idler.

Removed bracket

Lift springs up off shaft

Remove the 3 bolts from the motor housing.

Holding the nuts requires a narrow wrench.

Lift off housing

Pry tabs gently to remove bearings. I pry one less than the other to allow for easier reinstall.

I used SAE 30 oil, like an old VW.

Heated oil added, vacuum sealed following the Beolover YouTube video

I didn’t take pictures of the heating or sealing process incase my significant other were to see what I’m using food prep areas and tools for. Careful handling, hot oil is hot.

After 24 hours I heated the bearings with a butane torch and reapplied to the oil. Probable not needed though.

After another day I reinstalled.

Idler installed. Bearings installed. Pyramid of speed control installed.

I’ve replaced the original euro 50hz pulley with a pulley from a 60hz motor. I found snugging the pyramid screw not too tight is helpful for future speed adjustments.

As it says in car repair manuals; installation is the reverse of removal.

I’m really happy with how quiet the new idler wheel is and how consistent the speed is now.

Seems nice! But why do you heat the oil?

I use the process described here. It doesn't mention anything about heating the oil.

Kind Regards,

Hello Beogrowler,

can you tell me where you got the new idler wheel from? I think mine is causing some speed issues for my Beocenter 3500 so I'm thinking about chaning it.

Cheers!

Great description thanks, very helpful.

How do you guys get the motor centered when reassembling it?
And do you replace the felt?

No one? Do you just play it by ear or? ;-)

On another note I'm trying to upgrade my membership to Silver and it seems something is out of order, I'll start a thread about that at the appropriate place.

I don’t understand your question. It only goes back together one way.

In my original printed copy of the BG 1202/3000 service manual (see pic) it is stated that the motor should be centered using two gauges before it is bolted together. I found a scanned copy online where this is not mentioned.

Ok I installed the motor and put everything together and then the noise was unbearable. I sounded like something was grinding inside. Took it apart again and this time tried to center the motor using four round toothpicks. There's two "holes" on each side of the rotor, I stuck the toothpicks in those before bolting the motor together and then removed them again. Put everything together again and voila no noise.

Sorry forgot to take pictures, next time..
