Pioneer CT-F9191

There are two springs in the clutch you show. One provides a "slight" resistance to ensure clutch pivoting upon direction reversal. The other one provides the drive pressure to the clutch plates. There is a part inside that tends to split over time, and allows the clutch pressure plate pressure to spill out of the clutch, causing pressure to be applied between the clutch and its retaining E-clip. If the crack/split exists, it will cause REW/FF issues, such as you describe.

MarkTheFixer reworks these clutches at a very reasonable fee, with a quick turn-around. Search for his threads on the subject, for images of the inner workings of the clutch and the associated splits, problems, and fixes. I just had him rework one of my clutches, and he does a good job.

Enjoy,

Hello again,

Thanks for your comments. I have spent hours reading all different kinds of threads in this forum. I think I understand how the clutch works after a deep dive into MarkTheFixer excellent wiki. :)

So sorry if I am a bit stubborn. I can´t see that the "inner/drive" spring puts any pressure to the e-clip. ln the picture I´ve uploaded, I´m able to expose the axle around the e-clip only holding the down the rubber of the lower clutch wheel. If a crack would be the case, I think this should not be possible? Or am I wrong?

Should the clutch assembly spin freely without any resistance or drag? Or is some drag due to the outer spring force ok?

Thanks

Thomas

Thanks Rich!

This is what I have, a slight resistance. Sorry for asking the same question twice. I just wanted it to be confirmed since I have read both. I would be surprised if the clutch is the problem(even if in the long term a fix could be beneficial).

At the moment I believe it is the ff/rewind motor. I have when I remove the belt to the time counter a good speed in the rewind direction, the ff direction is working, but slow, when I lift of the back tension. But the clutch is never activated as the tape comes to an end in either direction.

I have only changed the tape sensing micro switch, could some of the other switches make a difference upon the voltage to the motor?

Regards
Thomas
