TEAC CX-310 - Help with pinch roller not engaging

[asmasmasm]

Hi all,

First time repairing a cassette deck. Noticed that the cassette was playing quite strangely - very intermittent sound. Took a look at the mechanism and saw that the pinch roller wasn't engaging with the capstan. It seems that there was a spring that was kind of dangling down, which should have been propping the pinch roller up. I saw that there was a screw on the end, so silly me thought ok I'll just tighten it and then it will be rigid and will be able to hold the pinch roller up. Well, it just got looser and fell out. The end of it look like there might be some snapped plastic. However, I can't really see any broken plastic left in the mechanism. Essentially, I have no idea of the nature of this piece and am not sure if it is fixable.

Any help on identifying the exact nature of this piece and whether it is perhaps repairable. If it is not, I'd prefer to be put out of misery so I can move on.

A service manual would go a long way in identifying the spring /purposelocation. The "piano key" type manual control transports are not easy to work on. This type of transport is full of small parts that have to fit together precisely to work. The other consideration is that someone prior to you attempted to "work" on the transport and broke off the mounting post. Most of those mount points are pressed into the main bulkhead and will require complete disassembly to fix if at all possible. I think you should try to get a service manual and/or move on to another project piece.

I found this picture online, does it help?


It looks like the spring is part no. 19 in the diagram below and fits on that post.
