The deck powers on and radio works

Tape player doesn’t work at all I bet no response from the unit .

It won’t play tapes won’t fast forward wound rewind won’t eject .

Could this be from bad solder connections or bad caps or does this sound like a different issue ?

Any thoughts ?

 

[Perry Babin]

What switch on the mechanism is actuated when you drop a tape into it?

 

[caraudioguy2100]

I replaced the belt since I saw it was stretched out .

I will have to see what switch is triggered when I drop a tape in .

With the new belt of no tape is inserted the gears will spin if I drop a tape in the unit the tape with not spin and just keeps ejecting .

Wondering do I need a even shorter belt or what would cause the tape to not spin and just keep ejecting the tape

 

[Perry Babin]

Do the capstans and pinch rollers turn when the tray is dropped with no tape?

 

[caraudioguy2100]

Yes

 

[Perry Babin]

Is the tape OK? Can you rotate the take up reels in both directions?

 

[caraudioguy2100]

Yes tape is fine it plays in another tape deck perfectly

 

[caraudioguy2100]

I can try cleaning the tape head and rollers ect to see if that helps

 

[Perry Babin]

Make sure that the pinch roller is tight against the capstan.

If the capstan and pinch roller are tight, they should be pulling the tape through and the take up reels taking up the slack.

Make sure that only one pinch roller is touching its capstan at a time.

 

[caraudioguy2100]

Looking at it some more the rollers don’t spin

So when I put a tape in the rollers don’t spin so the tape just sits there

 

[Perry Babin]

Are the capstan pulleys under the transport turning?

 

[caraudioguy2100]

In pic 1 the pulleys turn if there is or isn’t a tape in it .

Pic 2 the capstan stops spinning when a tape is loaded but the pulleys will continue to turn slowly .

 

[Perry Babin]

Do you mean that they slow down when a tape is inserted?

The capstans are pressed into the pulleys so they can't stop unless the pulley is loose enough to pull off of the capstan.

 

[caraudioguy2100]

They slow way down .

I can’t even see them turning when a tape is inserted

 

[Perry Babin]

turn them with your fingers to see if they get to a point where they begin to turn freely.

 

[caraudioguy2100]

They will turn freely until I instert a tape .

I’m wondering if I need a lil bit shorter belt ?

The belt was pretty stretched out and the guy guessed at the size of it

 

[caraudioguy2100]

I’m gonna explain this the best I can .

In the pic the black capstan is on a shaft and pulley

If no tape is inserted they will spin along with the gears when I spiny the pulleys by hand or with the motor

If I insert a tape the pulleys will still turn but the black capstan stops spinning all together

 

[Perry Babin]

The pinch roller is the black rubber wheel. The capstan is the shaft in front of it.

The white nylon disk with a gear around its perimeter, is the take up reel. The take-up reel has a felt clutch on it that allows it to slip as the reel of tape changes diameter.

The pinch roller and capstan should forcefully pull the tape through. Is the black pinch roller turning.

Cassette Tape Transport

 

[caraudioguy2100]

No the pinch roller is not turning

It will turn by hand with no tape Inserted .

But when a tape is inserted nothing turns at all besides the pulleys

 

[Perry Babin]

Are the pulleys that the belt is wrapped around turning?
