BeoGram 5005 tonearm too low

[supertom1976]

Hi,

I recently bought a beogram 5005.

Unfortunately there seems to be something wrong with the tonearm. I hangs about 1 cm low (please see pictures). I have taking the carriage apart and tried to find anything related to this in the service manual but can’t figure it out.

I would love to get some advice on how to fix it.

I attached a bunch of pictures to show the problem.

Thank you for your help.

 

Best,

Tom

Is it in play state?
If so, it looks right, considering the heavily set tracking force.

Does the white bar at the back tumble when lifting/lowering?

It’s almost like my 5005’s ‘normal position’ is the drop down height.

Hi Tom,

the tonearm should definitely be at the same height like the indicator arm. Did you try to adjust it like it is recommended in the service manual, chapter 5-2?

Kind regards,

Rolf

Hallo Rolf,

yes, I did. However screw C is broken on mine. It is however in the position not to lower the arm.

i think the problem has to do with the carriage. The arm just doesn’t seem to be balancing at the right height.

some more pictures for troubleshooting attached…

thank you for any help and advice.

 

best,

Tom

Screw B is the one that you use to align the tonearm with the sensor arm. Also spring 1107 does not appear to be attached at the top in your photo.

The spring is responsible for restoring the arm to its rest position. It appears you can move it to the proper level with your finger; therefore, it appears the spring has lost tension or was switched with one of the other springs. You should be able to confirm that by pressing on the spring’s top connection. The other possibility is that the counterweight is too far forward which for the tracking weight calibration. Ensure that when the tracking force know is at 0 that the arm floats when in Play mode.

Your picture of Part 1110, Holder, appears to be missing a rear piece S that sticks up and may have snapped off. The only solution would be to find a replacement.

Hi Mark,

When I compare my part 1110 with the picture in the service manual it appears to be OK. Both S pieces (the two little sharp cones) are there.

Can you please tell me/show me which part you think snapped of part 1110?

I still believe it has to do with “Schneidenlager B” of part 1108.

Does someone have a picture of the underside of part 1108, that I could compare with mine?

—and if anyone has any suggestions on how to fix/reattach that pin “Schneidenlager B”.

Thank you.

Relooking at it the second pin may be there. However, if you had an issue with the knife-edge bearing B not being there, the arm would not work at all. It’s possible the are was not properly refitted. Try following these steps precisely again:

Hi Martin,

I am not quite sure I understand.

Are you saying you would try to take out bearing T (is this the connected top side of the cast metal pin on the bottom (edge bearing B)) and replace the complete cast metal piece with something else?

Before I take the whole thing apart again, would you have a picture, that could explain what you are suggesting?

Thank you for any help.

Success!
I figured it out. I glued a small screw, with flattened head to the underside and now the tonearm balances correctly.

Just listened to first record playing on it. I am loving it!

For anyone else ever facing the same issue, I attached some more pictures.

Best,

Tom
