I recently replaced the rubber 'tires' for the idler wheels in the tape drive mechanism for my not working BC 9000 and installed new belts.  Once tested it did not turn.  Upon comparing the Take-up reels from my older Beocord 8000 deck,  this one was hard to turn.  It was really stiff.

The  manual does not show a way to fix this.  Can someone suggest how I an disassemble to clean and lube it?   (There is no expanded view in the service manual either).

Hi,

Did you set the brake pad correctly? It should be inside the wheel, not outside. I think I had the problem but that was a long time ago…

chilibt: Is your question about the plastic part not spinning easily on the metal shaft when that sub-assembly is removed from the main-assembly? (sorry if my description isn't very good)

Hi,  thanks for the questions. No matter how I try, I always leave out something important.

yes the brake pad was set inside,  and the stiffness in the Black plastic reel was not discovered until removed as in the photo.  It should rotate easily on the metal shaft, but this is much harder to rotate in comparison with the 8000 unit I used as a comparison.  It was so stiff that is became obvious a drive belt and/or tyre(tire) would not be able to move it without slipping.   I am thinking a lubricant needs to be cleaned off and reapplied.

It looks like the top cap slides off.  I tried with my fingernail and it did not move with moderate force (which caused me to stop trying until getting more info).

I am a bit apprehensive to disassemble plastic parts that are friction fit without some guidance so it does not break.

I had a very similar issue. Unfortunately, I wasn't able to figure out how to get it apart for proper cleaning and lubrication. It seems logical that, if it was assembled, it could be disassembled. I didn't want to risk permanently damaging the part either.

Mine wasn't that bad and I got it to run free by adding a very small amount of plastic safe oil and spinning it until it ran free. I would have rather restored it properly.

I understand, my thoughts exactly.

As there is a part number for each side, and a separate for the tip so they must come off?  Perhaps removal destroys the old tip and once on, the new tip cannot be easily removed?

Do you know if a safe solvent may be used prior to new oil?  if so what type?

Also there is a felt pad inside, does it have a "oil free" status?  If so this gets more complex.

The top cap can be removed with moderate force (go ahead, don’t be shy) and can be put back on. Many cassette deck reels use this assembly method.

Clean the metal shaft with some white spirit then some DTE oil may be applied inside the reel’s central hole (one tiny drop) before reassembling. The felt washer shouldn’t be oiled.

Thank you for the advice.

The cap did come off with careful prying using my fingernails, one nail on both sides.  Some twisting and tilting got it off with a bit of force.  It was cleaned and reassembled.  The cap clicked back on the grove in the shaft firmly making is a solid seat.  It is definitely a critical tiny piece not to be lost.

The result was a reel that spins like a top for several turns after a quick flick with my fingers.

The other reel was done also.

It is apparent the reels do not disassemble beyond what was done.

thanks again!

Terry
