DC Motor turning continously in Cassette Deck

I looked inside of an old cassette deck that I have TEAC V 307 to put a belt back on the capstan flywheel. I suspected correctly that the belt was slipping. the belt is old and i will replace with a new one, however, now when i turn the power on the DC motor ( connected to the capstan flywheel via this belt) turns continuously regardless of what 'play status' that I'm selecting. In fact it turns continuously even if no status is selected. I'm wondering if this is normal. when i hit FF, REV, Play, REcord, they all work correctly, its just that the DC motor is continuously turning independent of any play status. I don't remember it doing that when I opened the deck but then again I didn't have the power on when I opened it up.

Re: DC Motor turning continously in Cassette Deck

Yes this is normal. the deck utilises what is called a rolling transport and the motor runs continiously to allow for mechanical cam engaged functions to work.

The left side of New W-890R cassette deck plays at triple time. Right side plays normal. Tried to adjust with Pitch control but not the answer.

The transistor in the servo capstan motor is probably shorted- this happen now and then and you need a new Capstan motor. The question is most dual cassette decks are not worth the repair.
If the adjustment make no difference then that is likely the problem.

How to replace the belts in a Teac A300 cassette deck

The mechanism needs to be taken apart sufficient to get to the flywheel and capstan motor- this usually entails taking the metal motor bracket off the back. It is not that difficult once you have done one. I may have replaced 50 to 100 of them at Teac in Chicago. Also oil the capstan bearing when changing a belt.

Thaks for helping. My tape deck door has suddenly stopped working. the tape is inside and when i turn on the wpower there is a clicking sound. it is a TEAC AD-500 CD player/reverse cassete deck

Without physically looking at the cassette deck myself, I cannot be 100% sure the tape is wrapped around the pinch roller and capstan. The capstan is the chrome rod which the rubber pinch roller pushes to regulate the speed of the tape moving across the head. However it is approximately a 90% chance the take up reel for the tape stopped working from a bad tape or a loose belt which drives the tape take up reel. The clicking sounds like it could be the auto reverse solenoid because it thinks the tape has reached the end of play. The fun part is to remove the tape which you may have to disassemble the front panel if you cannot gain access to the tape from the top or bottom. You will need to cut the tape and remove it from the capstan and pinch roller to open the cassette door. Sometimes you can remove the capstan to free the tape. Once you have cleaned all the tape out of the unit make sure the belt for the take-up is good. If it is glazed, cracked, loose or broken order a belt. Clean all the pulleys and capstan and replace the belt. Your unit should be functional after the above procedure.

My Nakamishi Cassette Deck 2 is eating tape. It switches off when it does, but how can I fix this? From the look of it this cassette deck has the same cassette drive as the DR-8. Is that correct?

It could be the take up spindle does not have enough torque causing the tape to bunch up after the capstan. If you open up the unit you will notice ether belts or rollers for the tape drive. If it has belts you can replace the belt after cleaning the pulleys. If it has rollers you may be able to clean them with a rubber cleaner (not alcohol which will dry the rubber and cause glazing). Make sure the capstan and the pinch roller is clean using a rubber revitalizing cleaner on the pinch roller. "Goof off" from a hardware store is great for the capstan if it has a lot of metal oxide on it.

A 303 cassette deck - the belt has been changed. The feed spool and capstan turn fine. The take up spool does not turn and play stops after 5 sec. Take up spool is fine in fast forward. Help !

This is a case of a failing reel motor. What happens i sthe brushes become aged and wear down and the motor has what they call a dead spot on the Commutator. The motor will work fine at high speeds as the inertia is working for it but when you use a slow speed as in play mode the motor hits the dead spot and stops. You will need a new reel motor in the most likely case- I can service the deck if you want at Skywave Tape Deck Repair Chicago area. I will most likely put a new motor into the deck.

TEAC CX-370 Cassete Deck

Could be a worn out belt? The cassette loads it the drive down too much. Hence why it turns with no tape.

Motor plays at a very slow speed

capstan belt may be failing. check this by removing lid and touch the capstan flywheel when running. if it is easily stalled/slow to come up to speed and or the belt slipping badly then belt will require replacement.

Deck turns on but doesn't do anything else. Motor runs.

The main flat belt you describe is probably the capstan belt. The "flywheel" you describe drives the capstan. I don't know the model number of your deck (it would help if you could say what it is), but I'm pretty sure that the flat belt should go around the big flywheel and then around a motor pulley that should be very close to the flywheel. The motor should spin the flywheel even if the play/FF/RW buttons are not engaged. This might sound funny, but the other "O" ring belts might be very important (control motor belts) or not that important at all (tape counter belts)--it depends on the model number of the deck. One more thing: Every healthy capstan belt I've ever seen is NOT sticky and does NOT glom onto itself. That belt sounds like it is very old and needs to be replaced.
