Grundig TK149: How NOT to change belts

It's always annoying when a belt snaps on a reel-to-reel machine.
If you don't know what you're doing, changing them out can become quite a task.
Out of ignorance, I took the whole damn machine apart, which isn't necessary, but it's still fun to watch.
Enjoy!

Well, this is not the method how belts are intended to be changed. Instead of taking the whole damn thing apart, here's an easier way: kzbin.info/www/bejne/m3LbkKSFa6aEgJY

Brought back a lot of memories from the 70's when I was a TV Engineer, the City and Guilds Examination also covered Radio and Tape Recorders. Many a happy hour pulling these apart, repairing and then re-assembling. If memory serves me right, the PCF valve (tube) is for generating the high frequency for the erase head and carrier frequency when recording... good old days... now everything is done with one chip, bring back the seventies I say!

[@AstraWerke]

[@waltermelyon4300]

Repair is a beautiful word.

[@alexbeaulieu9074]

oh yes it is

[@jd3552]

Excellent content, it's just like assembling a clock movement! Start from one end and proceed. Radio horology.

[@alexbeaulieu9074]

thank you for this i have a tk 146 which is similar this is a big help to me hello from Canada

[@AstraWerke]

Well, I'm glad I could help! :D

[@frankmuller985]

völlig falsch!! Der Riemen wird von unten gewechselt. totally wrong!! The belt is changed from below.

[@chrisbergner7077]

You're absolutely right ! Never loosen the chassis for changing the belt !!!!!!!!!!!!

[@jaykay67design]

Classic Grundig design and and tidy inside

[@sheep1ewe]

Awsome! Great instructions!

[@AstraWerke]

Thanks :D

[@timescoffery7662]

Great video. Could you help me with instructions on how to replace the drive belt on a Grundig TK55 recorder.

[@shakilrana2868]

You are great

[@jonvincentmusic]

Pretty sure you’re supposed to do it from underneath so the whole mechanism doesn’t fall apart like a clock movement.

[@selmansenkalp]

There is no space underneath to operate.

[@h.n.jahangiri]

Hallo How and where can I buy the belt of this model, please guide me, thanks

[@AstraWerke]

They're sold via ebay :)

[@sencer-sari]

2 other belts were existing but not shown how to change at this video

[@hannah9418]

Where do you suggest getting new belts for these old Grundigs? I have an SO 171 console unit i'm trying to get working just so I can get the tape to tape running and pull some old audio recordings of a late relative. I managed to get power to the tape unit and it's spinning up but i need 2 belts, not sure how to measure/spec (tightness level) or where to source these custom o-rings

[@AstraWerke]

Just type the make and model into ebay, you ought to find something.

[@فكروتدبر-ف8ذ]

It is wrong method to replace the belt and defecult.thr right method from the back (bottom cover) u will find entrance to the motor belt cover 15:48 under the speaker .remove the 2 screw and install the belts.thats all.

[@AstraWerke]

You may be able to change the tape counter belt that way, but how would you get the drive belt around the flywheel without taking the axle out of at least one of the bearings?

[@فكروتدبر-ف8ذ]

@@AstraWerke remove the 2 scre and u will find it is easy to install the belt aroun the weel.i do it evry time when the belt cut

[@فكروتدبر-ف8ذ]

@@AstraWerke 15:48 u will find small iron cover with 2 screw blow the speaker directly.remove and install belts arround the axe

[@AstraWerke]

@@فكروتدبر-ف8ذ My god, I wish I had known that before... Well, when the belt rips again, I know what to do - thank you!

[@AstraWerke]

@@فكروتدبر-ف8ذ Well, the engineers back then were alot smarter than me xD Thanks alot for pointing it out!

[@KresimirPrelec]

super

[@lizj4101]

Can you tell me how this TK149 records? I have one but can't get it to record!

[@AstraWerke]

There is a knob on the left of the top face. Select between "Automatik Sprache/Automatik Musik/Manuell/Trick" what you want to record (Speech, Music, custom) by twisting, then press the knob down and switch the lever on the right to "Start" simultaneously.

[@lizj4101]

@@AstraWerke thank you I will try that! Amazing many thanks.

[@barryaustin1544]

Much easier from below… remove the plate holding the lower flywheel holding point

[@PAL25FPS]
