Hi,

I have a BC9500 whose tape drive is misbehaving. The play function works perfectly. The belt seems to be fine. The plastic pieces all look fine. The mechanism moves smoothly if pushed/rolled with the finger.

Problems:

1. After switching on the system if I press A.TAPE, the Capstan Motor switches on, even without a cassette. I can see the flywheel spinning continuously. switching to CD does not have any impact. I can put a tape and play and everything is good. I can switch side by pressing TURN. No issues. Pressing STOP disengages the head but the capstan motor is still on. Is this normal behavior ?

Completely normal behaviour.

2. FWD/REW functions doesn't work at all. On pressing FWD/REW There is a initial hum of motor and then clicking sound and nothing.

I removed the tape and pressed the micro-switches and if I FWD/REW then the roller turns for couple of seconds and then switches to other roller turning for couple of seconds and then stops. But with a tape in, nothing except the humming.

The tape deck would do that without a tape in. It relies on the movement of the opposite spindle to determine when to stop and change direction.

The lack of RW and FF will be caused by a slipping belt. Make sure you get the correct replacement. Don’t get a cheap poorly fitting one off eBay. Too tight will damage the motors bearing and too slack won’t work.

Member Dillen can supply the right one.

Any guidance on resolving the above will be appreciated !!

Thanks.

Thanks Lee.

Yes, that's what I am trying to do. I need belts for a BeoCord 5000...now trying to find if I need other parts for the 9500. Send in one request to Martin instead of batches.

9500 - The belt seems to be fine as the playback function works ok. As per my understanding, the FWD/REW function is handled by the motor and the clutch. No belts involved. 

Martin,

Thanks for the Belts. I am happy to report that the BeoCord 5000 is back to life.

But the BC9500 is still an issue, even after putting the new belt. The FWD/REW functions are still not working.

Here is what is happening -

1. Pressing FWD/REW moves the head from normal position to play position (engaged to tape).

2. Tape plays for 1 sec or so and then pauses. Even if keep the FWD/REW button pressed nothing happens.

3. Pressing FWD/REW again, disengages the head and it goes back to normal position.

4.Pressing FWD/REW again, repeats step 1.

In all this, pressing A.TAPE/Go works fine and the tape plays without any issues.

As mentioned earlier, without the tape in if I press the micro-switches at the bottom and press FWD/REW, one of the the black roller spins and then switches to other side and stops.

A quick glance and nothing seems to be broken or out of shape.

Any guidance on next steps in troubleshooting ?

Thanks !!

Video seems to be set to private.
I can't watch it,

Always a good idea to clean and relubricate the tape reels, particularly if they don't rotate freely (with brakes released).
Take off the tiny locking washers (carefully!), and lift off the tape reels. note the small round bronze plate inside (vibration stop).
Clean and add a little white lithium grease. 

Martin

Cleaning and lithium grease done...no change. 

Video should work now...

In normal operations, does the tape head engage for FWD/REW operations ?

In play mode, makes sense if you are searching for the end but without play mode engaged ?

That board must be cleaned.

No Martin, I haven’t replaced anything on the tape mechanism except the belt.

Another video with a see through, no tape, head-cleaning tape. - https://youtu.be/zxT45n2ZKIs

Same result.

I am getting 4.2V on the wind motor. Not sure if that's good?

The board is cleaner than before.
