I can save you a lot of time here. If you adjusted the vertical/horizontal settings and it's still scraping - there's a further adjustment to the clamper mechanism which you can fiddle with.

However... I can't remember what it is. ❓

Is this setting in Testing Mode? I tried TM71 and TM73 it didn't really help. I can see that part 9121 2854207 Clamper arm is misaligned. Anyway to adjust it without opening up the unit?

No, it's a manual setting done with a screwdriver I seem to remember!  I think you need to remove the glass (two allen bolts) to get to it.

You would be best advised to up your membership to at least silver and get the service manual where the sequence will be explained in an easy to follow series of numbered steps.

Got it, thanks.

Hi,

The Mark III version no longer has the screw type adjusters to level the clamper arm like the Mark I had. If you're sure that the part you identified in your first post is what is not level, (it appears the bottom of 9121 2854207 clamper arm is making contact with the CD 4) then it's possible that the screw holding the clamper arm on the ride side may be loose.  The Mark IIIs have a small plate and a screw on each side to mount the clamper 9116, the plates are 9115, screws are #32.

If you release the sledge and then remove the glass, you can remove the top plate (9114 -see manual) which will then allow you to see if both screws (32) are tight on plates 9115.

If they are ok, it's also possible that the plastic clamper arm is not fully seated in its attachment point. That piece is tricky because the left side of it slides onto a pin while the right side (which has a cutout on the top of the shaft) then snaps upward onto another pin.

At this point (with the top plate removed) you can see if the clamper arm (9121) is fully seated on the right side, and that it is screwed onto 9116 (with screw #37).

It's a good idea to clean the inside of the rails where the sledge travels, dust builds up in there and causes problems too.  

The entire process I've described should take 10 minutes.

1. enter testmode

2. release sledge

3. remove mains

4. remove glass

5. move sledge to middle, remove cover plate (see manual)

6. check 2 screws to make sure they are tight

7. if they are both tight, check clamper arm (9121) to make sure it's mounted properly and the screw is in place (#37)

8. replace the cover plate

9. clean the insides of the rail slots for the sledge, I use a soft cloth and windex

10. mount some CDs and manually slide the sledge across all CDs in all slots, both directions.

11. replace glass.

12.connect mains.

13. in testmode, run TM71 and TM73 (see manual).

If you still have scraping then it's very likely you need to replace the rocker arm (9134 2854196 Rocker arm) which is very simple and costs about $14 US, still an available part.

Good luck!

Hi Bill,

Thanks for the detailed instructions! I finally had some time last night to open up my unit. My Mark III actually has the screw adjusters as outlined in the Mark III service manual... Do I have an older version? Luckily I didn't have any need to move the sledge or get to the rocker arm. However, I did remove the clamper arm to make sure it wasn't bent. In the end, it took a several attempts adjusting the screws (and removing and replacing the glass) to get the clamper arm parallel to the top plate. The CD mechanism runs so smoothly now and I am so pleased! Before, in addition to the scraping, it would make a clunking sound every time the carriage passed over CD 4 and CD 1. So annoying!

Thanks again to you and everyone else who has weighed in. Would have been a pain in the ass (and expensive) taking this thing to the shop!

P.S. Where can I purchase Beosound 9000 parts? I actually need part 9203 (alternate cable cover).

Cheers!

Hi,

I'm glad that worked out! I'm also very embarrassed that I misstated the lack of adjuster screws on the MKIII. The last time I had my MKIII apart I thought there were none, even though I've adjusted my MKI twice now. Silly me. I had to pull my MKIII apart just now to verify that it does in fact have them as I had convinced myself they were not there.  Oops. Sorry about that!

No worries. I wasn't even sure they were screws at first. Had to double confirm with the service manual.

By the way, do you know a good source for replacement parts?

Thanks!

Most of the 9000's that I sold required that particular adjustment.
