Hi,
First post so hello everyone and I hope you can help me.
I have just acquired a beogram 5005 as my voyage back into the beo world.
I used to have a full 3000 series system, master, gram, cord, CDx (a year or so later) 4x Rl45s. Everything wall mounted and regretted the day I sold it all (first wife, say no more).
So back to my new (old) purchase. A good clean and some adjustments later and all is pretty good apart from a scraping sound when the tone arm get close to the end of the record. I have identified that the cast turntable support frame is just touching the wide black disk that turns with the tone arm carriage.
Any ideas how to stop this? I'm guessing there should more space between the parts but not sure how it could be so close?
Any ideas gratefully received.
Many thanks
Jerry
This is a common problem with these decks,particularly when using the new "heavyweight" albums.
You will need to re-tension the turntable subchassis springs to raise the platter so that the record clears the deck plate.The adjustment is done when the pu carriage is near the centre.
Instructions are in the service manual on site,but you will need to change your membership(well worth it too!)

Thanks nick for the detailed reply, but if raising the player is a case of retensioning the three springs, I have done this but it doesn't separate the chassis from the base but rather lifts the whole floating table. Is there a way of creating more separation from the player and the table? I have a pdf of the service manual if you can point me in the right direction.
If it is a scrape type noise then raise the rear of the chassis slightly. If it is more of a click then re-position arm G as it may be rubbing on the inside of the skeleton wheel.

I've being trying to upload a video without success,I have a PDF of the service manual but I can see how to make the space between the turntable frame and the pulley disc greater to so it rubbing?

Videos as promised.
Sorry,but I misunderstood your original post.You're finding that the skeletal turntable is fouling on wheel 1634(as shown in drawing) when the pu carriage reaches the centre of the disc?
With the platter in place,can you measure 53mm between the platter surface and the top of the pu arm ?
Unpower the machine of course,and slide the arm across to measure this.
With the platter in place (silver record deck) its 19mm from the surface of the platter to the top of the tone arm.

It's almost like the whole skeleton platter need to raise from the floating tray by a mm of so to give more distance between the plastic tone arm dish and the skeleton disc bottom edge.
Is there a way of raising the center main bearing shaft?
Sorry,but I'm confusing the issue here!!! The measurement should be 53mm between the top's of the pu arm/indicator arm's,and the top surface of the floating chassis.(I should have gone back to Spec****rs again?)
I think that you are correct in that the turntable is too low,and also perhap's not turning evenly either?Does it's height vary as it turns?
I understand from other posts here,that the turntable bearing support can in fact collapse,but I've not seen this myself.
Any insight/solutions from other member's please?
Sorted! But you're not going to like it.
A couple of light ish taps on the tip of the center pin essentially pushing the bearing further into the skeleton frame and thus lifting it clear of the pulley disk.
Working like a charm and back to how it should operate.
Thanks for all the onsite though.
No doubt I'll be back.
I have exactly the same issue, same noise as on the video you posted. I did tap (gently) the wheel 1634 but it has not worked. So I have pushed some pression (gently again) on the wheel while I was turning it (to have equal pression everywhere) and it work like a charm !!!
So the problem is the wheel 1634 which going up with the time and need to be lowered...
Thanks everybody ! Great help !
