If it is making noise chances are that it is also running too fast. The solution that I have found to be reliable is to change the motor with a new one. The only problem is that you will putting in the same defective made motor that you started with an a good chance that down the line the thing will have to be replaced again. It is like you are renting motors for this unit not buying them. This is the largest mistake Teac made in designing this deck. Otherwise it is a good machine.

I have Akai gx 230. Its doinf Rew and FF but Play not working, though engages. Tape does not move. Can it be tape threading problem?

Could be either. If you can do some testing, check for power to the capstan motor in play configuration. If there is power at the motor terminals, the motor itself may have failed.

Capstan makes the reels drag sometimes even stops

Replace with a capstan belt from Marrs Communications it should be a 16.8" IC belt. Fred know which one if you tell him the model.
The capstan motor can also be worn out. These need to be taken apart and examined at to brush life and to see if it has bee overheated. I get a lot of motors that are burned up by customers.
It is a $150 part.

Tehnics sl-bd22 noisy motor what to do?

If the bearing is worn to the point of a rattle and a small amount of silicone oil won't stop it, then it should be replaced or the motor replaced. These bearings are normally lifetime impregnated with lubricants and can sometimes dry out with use and somewhat seize up causing what may sound like a rattle. If the motor shaft has worn down enough at the bearing point, then a rebuild or replacement is in order.

Reel to reel will not play

You do not mention the brand or model number which to answer the question effectively is needed- different machines are designed in different ways. The function of the fast wind and the play mode only differs in that in play a capstan is involved that regulates the speed and the reel motors just do the take-up of taper and a little back tension for the supply reel. You may have either a sticky Pinch Roller linkage or a non- rotating capstan shaft that might point to a loose or broken capstan drive belt. There are also the condition of the Pinch Roller surface and the surface of the Capstan shaft that can be glazed or rubber hard and non-compliant. The rubber Pinch Roller can be re-rubbered, the capstan shaft can be reconditioned and the Capstan Belt can be replaced. Capstan bearings and motor bearings need oil once a year as well. I hope this helped to some extent- I have been working on decks now for better than 40 years.

Cr2406a cassette plays so fast you can't understand words

The speed of the deck is regulated by two things- one is the pinch roller engaging the tape to the capstan shaft. If this is happening, then the capstan belt may have ridden up on the outer edge of the motor pulley OR the capstan motors DC servo control has a shorted transistor in it and that means you need a new motor. I have just obtained some motors for cassette decks that might work in your unit- the only way to get it fixed at this point is to have a Technician work on it. It will not fix itself nor improve.

Noisy capstan which runs continously

most tape decks are designed so that the spindle will run when powered on. when you press play or record, the pinch roller elevates the tape to the spindle, tape starts to travel.

noise is basically from the mechanism, or deteriorated in time as yours is an used one. if you are lucky to find some good pinch roller rubbers of same diameter, replace them.
