HI, I purchased new belts for my tapedeck (2 actually: a flat and a square one) but I don't know how to install them. The square belt is visible but I cannot find the flat one. Can you help me?


The flat belts are usually the one from the motor to the flywheel or "capstan." Most people don't realize this, but the capstan and pressure (pinch) roller is what actually drives the tape in the play mode. The reels are used to maintain tape pressure and perform rewind / fast-forward.

Most tape decks have sensors monitoring the reels to make sure they're moving. Otherwise a jam is indicated. Belts usually drive the reels and they get old, stretch and/or break.

Look inside it to verify.

Using a search engine go looking for the belts for your model and maybe even find videos showing how to replace them.

That is what WE do.

1980 Akai GX 4000 D does not record and has slow tape transport


Hi wakjh

sounds like 28 years of service has gotten the better of the old girl. You will need to replace at least the capstan belt to get the speed back up. It will need attention in other areas also. reel idler tyres, takeup clutch, counter belt.
You can get a complete belt kit from here.

TEAC TV770 no play


Hi again

If it uses the same idler(i honestly cant remember now) it may still have drive in ff and rew but not in play because of the reduced torque required and much less mechanical coupling force to the drive surfaces of the idler to the reel base as a result. Cleaning idlers with acetone gets the best resuts. Takes the top layer off!! Be careful not to get it on any non greasy plastics or and external casings(will leave marks). I often use an emery board(for finger nails) to get a decent new rubber drive surface if I cannot reshod a failed idler with a new rubber tyre. Let me know how you go :)

Hi saabangerman

The unit sounds like it has a take up clutch or takeup idler problem. Check all the drive assemblies in the unit. Remove the cover from the front of the transport inside the cassette well, and check the condition of the idlers and reel base drives. The counter belt can also gatherup and prevent the takeup reel from working correctly, or fire the auto stop mechanism preventing it from playing, although that sounds to be ok in this case as the unit will FF and REW ok. The takeup drive is supplied by a different drive idler as it requires much lower and more controlled torque. This unit was always considered to be a great tape deck and is well worth a bit of attention for restoration. You can get a new belt kit for $19.00 from here

I am more than happy to answer any other questions you may have about it, just give me a hoy :) Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

Nakamichi BX2 will not take-up tape and play


This may be a reel sensor problem, or the rotation of one of the reels is stopping for some reason. Most of the time, these faults are mechanical. There can be worn belts, or drive wheels, or gears, and etc. Sometimes there are faults in the electronics where a sensor is not being read properly.

The unit should be properly checked to evaluate the fault.

Tape deck not working


Sounds like a motor problem. Try turning the motor by hand to see if it's bound up.
