OK guys, picture this. I am minding my own business listening to my Beocord 8004 and it just stops playing.

What the heck? So I press PLAY and the head engages and immediately disengages. I tried this several times with identical results. Confused

Tried the GO feature, same thing. Took the tape out, retried, no difference. Then tried another tape, same result.

Grumbled and went back to my Beolab. But out of morbid curiosity I tried pressing PLAY one more time and it worked like nothing had happened. Played the entire tape.

This is a restored (top to bottom) deck not a Beocord that just came out of a church rummage sale, so I don't understand why this should have happened.

Any guesses gentlemen?

How well does your Beocord 8004 fast forward and reverse operate? When you had the Beocord 8004 restored did you have all of the rubber parts replaced or just the two belts? Martin supplies a rubber wheel kit that is crucial in replacing on these type of Beocords. If you haven't had those rubber wheels replaced then that would be my main suspect.

Another possibility is if the cassette holding tab isn't doing its job and there is some play in the cassette when the Beocord head assembly engages. If there is some movement there the head will disengage. It's hard to say for sure without seeing it but if it happens again try holding the cassette from moving with your hand and see if it starts playing again.

It was a complete rebuild, & the cassette mechanism was entirely replaced. I doubt it was necessary, but it was.

There IS an issue with the cassette holding tab as one ball bearing fell out a couple of years ago. Some tapes play fine, while other require holding the cassette in place when pressing play, then you are good to go.

Yes fast forward and reverse work properly.

I was really surprised when it suddenly stopped playing and perhaps more so when it started playing again without any problems, the whole tape and both sides.

I posted the question because if it is a mechanical problem, I probably can handle that. If it is electrical, one more item waiting in line for the repair shop.

I just tried everything again, FF, reverse, and play and it is like it never happened.

Thank you very much for your insight.

It sounds like a mechanical problem to me. So you are missing one of the ball bearings? The three ball bearings aid in the head assembly smoothly engaging so if one of those is not intact it could cause an occasional problem. You mentioned your are good with mechanical things. I would take out the cassette assembly and check it thoroughly again. I think Martin just started providing the rubber wheel kits for these Beocord models in 2015 so if yours was restored prior to that then it is likely those were not addressed. Can you ask the restorer if that is the case? The reason I bring it up again is because I have had Beocord cassette assemblies that looked perfect and moved easily by had but still didn't perform as they should until those new wheels were installed. The installation of those would be pretty easy for you I think.

If you need some bearings or cassette assembly parts send me an IM.

Good with mechanical things? Or so I claim.

I have the ball bearing, but did not know what to do with it.

The restoration shop that rebuilt my Beocord 8004 is the same one that did my Beomaster 4400. If you know my "history" you might have an idea of the magnitude of this problem.

The gentleman in question did not ask me, he just decided that my cassette assembly was "Not to his standards" and thus he replaced it with a NOS assembly.

At least I got a couple of years out of it, and he did get all the LED's to work properly. (He missed 1, but I don't want to talk about that.)

I really appreciate the offer of parts, but I spent a considerable amount of time trying to figure out where this ball bearing came from, and ended up totally befogged, maybe an idea of how to put it back would be in order.

Please understand, I ONLY work on my B&O equipment out of absolute necessity not because I am talented in this area. With such limited knowledge there are times I get "lucky" and get everything right, 4000 series Beograms appear to be my forte, but I changed the belt (thank you Martin) on my stunning Beocenter 9000 and it still isn't right, lubrication is still required.  If I was anything like you guys, I would have KNOWN to lubricate the mechanism, but I was happy to just change the belt.

I will keep Martin's replacement wheels in mind.

I dug up an old picture I had of a Beocord 8004 I restored. The red arrows in the picture show the locations of the three ball bearings Beocord 800x - 9000 cassette assemblies have. The flat, metal plate springs mount to a plastic holder via one screw. Each spring has a notched out trough for the ball bearing. Often the plastic mounting post breaks on one of the outer springs so the pieces get lost. Check your cassette assembly and make sure all three metal springs are there.

Here is a better picture from a Beocord 9000 I restored. The ball bearings and their mounting is the same as the Beocord 8004.

Fantastic! One picture us worth a 1,000 words and all that, but now I can get that annoying cassette issue resolved. I can not thank you enough! Big Smile

You are welcome. Yes, it is so much easier to communicate when there are pictures. That is why I take so many...plus I need good references when I do the next project.

With so much experience with cassette recorders, I hope you won't mind if I impose a bit and ask a real "basic" question of my next project in line, the Beocenter 9000 cassette mechanism.

I was having issues so I asked Martin for a belt and that made a BIG difference. However, something(s) is dragging in the mechanism, sufficiently at time to make it reverse direction.

In hindsight I should have lubed the cassette unit when I changed the belt, but I "thought" the worn belt was the whole problem.

OK, so the "plan" is to go back in on the weekend and lubricate all the moving parts I find, but perhaps you have some guidance for me, that is what not to miss and what to avoid.

I think my "ego" is still smarting from the rebuff I received from my tech who was picking up where I fell short with my Tandberg 9000X reel-to-reel. I really thought I had cleaned and lubed everything, but was told, "You got all the obvious stuff, but you missed a few points."

Anyway, any guidance/direction you might have for a proper lubrication will be most welcome.

Thank you!

Hi Jeff, I am afraid that all of my cassette mechanism experience is with Beocord 800x - 9000 decks. I haven't touched any of the cassette assemblies in the Beocenters (even though I do have Beocenter 9300 & 9500 units). For the problem you describe with your Beocenter 9000 I would probably suspect some mechanical sensor first and an electronic problem second. Maybe you can get your hands on a spare Beocenter cassette assembly to swap and check with.

I suppose it could be a sensor issue or an electronic problem, but there is a DEFINITE slipping sound coming from the new belt, rather unmistakable. Once it begins to play then all is well. 

As such I feel lubrication maybe what is needed. In this particular case I think you will forgive me for hoping I am right as IF it is an electronic failure, that is outside my limited abilities.

I will check out my Beocord 8004 shortly, it has played three tapes with no hiccups, so I believe you are right, it is the ball bearing issue.

And like you, I also have a Beocord 9000, one I expect no trouble from as it was "attended to" by Martin.

Thank you for your most welcome help! Smile

Hi Sonavor,

Opened up my Beocord 8004 today and with the help of your FANTASTIC photos located the problem immediately. Unfortunately the post that holds the panel and ball bearing had snapped off. Not going to let a little thing like that stop me, a bit of super glue with baring in place and problem solved.

OK, not quite. In opening the deck a light green wire broke its solder point going to the sensor to see if a cassette is in place. Removed the excess solder and re-soldered the wire.

NOW problem(s) solved.

I can NOT thank you enough as without your guidance and VERY helpful photos I doubt I would ever have gotten around to fixing this relatively small problem.

One down, and I am taking a quick break trying to get the cassette working correctly on my Beocenter 9000.

Then if THAT goes well, I need to add length to all the control buttons on my newly rebuilt Beomaster 1600. Even the on/off switch doesn't work, so this is unacceptable. None of this is the fault of the shop, just something about the 1600 design that is frankly problematic.

Anyway, I digress, THANK YOU  for solving my Beocord 8004 ball bearing mystery and problem. You just MADE my weekend! Big Smile

Hi Jeff,

Very glad to hear you solved the Beocord 8004 problem. That is also the main reason so many of us on the forum participate and request other posters to use pictures to explain their problems. As is often said here : "if there isn't a picture then it didn't happen" :)

Regards,
John

Hi John,

I may have done the work but YOU made success possible. That ball bearing lodged in the mechanism and I am so glad I held on to it. I had NO idea where it had come from.

Your photos really made this repair easy and simple and I really appreciate it!

As I am from the south my folks would have said, "You have earned your place in Heaven."

BeoWorld is just such a fantastic site to share problems and triumphs. And this is a small triumph! Big Smile
