Hi-Fi Tandberg 3000 series open reel FF and REW problems

In actual fact the model number of this one is 3041X ...but they all seem to be very similar...3000 series.

I have this now playing tapes well ...but FF and reeind is barely there even though the main belt for this action has been replaced..

Finding a manual was at best tricky ...but sadly it is very uninformative regarding mechanical issues.

I have a feeling the problem is down to missing clutch pads between the upper turntables left and right ...and the nylon pulleys beneath them.

I may be able to fabricate something to do the job ...BUT ...I cant see any way to remove these 2 turntables on which the reels sit...and there is no disassembly instructions in the poorly scanned manual I have.

Does anyone know how to do this ?

has anyone worked on a Tandberg reel to reel before and can advise ?

Please help if you can ...this is driving me nuts...and could be fixed with more info.

@vipersan have you checked the service manual in the forums' data library?

Just grabbed a copy buddy ...

certainly a much better and clearer copy than mine ..so thanks for that.

Sadly still not clear from the diagrams how removal of the turntables is achieved..

Maybe the spindle is threaded at the base ..and a special tool needed ?

I wont be giving up just yet as the missing friction pads shown clearly in the manual are simply not there any longer..

crumbled and turned to dust with age I guess.

Why make life easy when you can make it hard..?

Looks like my guess was right about the spindle being threaded at the base..

What looks like a plastic nut ..

of course I hadn't got a suitable box key/spanner ....and a pcb right where you dont need it had to be removed and pushed to one side..to get access ...which of course required a deeper disassembly of the case.

Anyhoo ..I finally got to unscrew the nut with pliers...and the left turntable is released..

At least one of the friction pads remains so I can use that as reference to hopefully construct something similar to glue in place..

The right turntable has none at all ...and wont be as easy to remove on account I first gotta get the counter pulley off..

Why do I do this to myself ??

@vipersan For times like this, resort to the service engineers' prayer.

“Our gaffer who art at the bench, hallowed be thy task, thy example shall be followed, our duties guided in all things electrical. Forgive the sins of the designers, who not thinketh of the service guy. Lead us not in to temptation to curse their name, or question their existence. We shall persevere, forever and ever, until the job is done. So be it.”

There's a shorter one as well, usually uttered as an expensive bit of silicon expires in a cloud of smoke:

"Please Lord, give me the last five minutes back".

Been there, done that.

Well I found some solf adhesive backed felt floor protector 4mm thick on fleabay...so ordered some..

Hopefully I can cut the shapes I need and make new pads which currently are flat ..crusty and knackered...so no grip possible....and measure at 3.5mm thick.

I wont be relying on the adhesive already on this ...I'll use some superglue as well..

wish me luck..

I was hoping to find circular felt pads with a diameter of around 70 to 75mm ..which would have simplified the job...but wouldn't you know it..

Not available or out of stock.

cest la vie

I really wouldn't.

Superglue really isn't the adhesive for this job, you'll be better off with the adhesive as supplied on the felt.

Good luck - I have a particular hate/hate relationship with these Tandbergs after one struck me on the head in my store and nearly knocked me out. When I discovered it had a major fault after all my efforts to repair the wooden surround and replace the pinch roller, I took great pleasure in propelling it with much force into the WEEE skip at my local tip.

Fair enough...

I'm just a bit doubtful as to how strong the adhesive backing is...

What I wont do is try and clean the crap off from the original pads...but instead fit the new ones in the spaces between ...

See the photo which would make more sense I think.
