Hi, I'm repairing an AIWA HS-TA161v and while I was closing it back, a spring came out and I'm not able to understand where it was placed. I guess it must be coming from the pinch roller mechanism. I can't find any manual service on the web. Could you please help me to understand how and where this spring was installed?:
Based on your photo, I notice the pinch roller does not sit in the correct position. It should be much closer to the capstan than it is now. The pinch roller should be connected to the head carriage assy via a spring and I believe that is the spring. Where it was installed ? Probably on that bracket on the right side of the pinch roller like I marked in the picture.
Hi, Yes, I put pinch roller in that position just to show it better in the picture. Exactly, I also think that spring came from there. I will try soon to put it in that position as you suggest. Thanks
It looks like this is how it's supposed to go. Please share what you did on this unit and links to parts like belts for reference, so other people fixing this unit will have the info easily accesible.
Problem with this unit is that it was stopping after some seconds and Play button was going up again, so I went to open it and check what's wrong. It was kind of stuck and now should be fine. Regarding the belt, I didn't order a new one but I'm attaching a picture here of the original one.
Me again! Does anybody knows if this piece shown in the picture is complete or partially broken? This is coming from the hole in yellow, and about me there something wrong or missing with that part marked with red arrow as from time to time is getting stuck in one of the gear while spinning and is not allowing the play button to stay down. This piece seems be touching something behind one of the gears internally while spinning, but not all the times. For example, it depends on the position of the unit, if upside down problem appears, if i change position of unit the issue suddenly disappear. Sorry if I can't be more specific but I'm not skilled enough. Thanks for your advices.
From the picture you posted, it's not clear if the part is broken or not. You need to take more pictures from different angles to see how the plastic looks like. The part itself does not look to be part of the latch mechanism, the latch is most likely metal and closer to the buttons. To me, this part looks like it could be part of the auto-stop mechanism which if triggered permanently would indeed cause a no latch situation on the PLAY button. It's not clear if this mechanism auto-stop is done by a level which is pulled down by tape tension or by the takeup reel rotation stop. For reference, since there is no service manual, please post some photos showing the entire mechanism both front and back. Question is: if you don't install that part at all, does the mechanism work correctly ? Do you have auto-stop with it taken off ?
Hi! Actually I removed that part and unit was working perfectly from the mechanical perspective, but then sound was not good and when moving it, the speed was kind of lightly changing. Does this piece perhaps maybe work as a friction or stabiliser? Or yes, this piece is maybe allowing the auto-stop, you're right! This little piece came exactly from that hole marked in yellow. However, we can forget about this case as I messed up a little bit the things sanding this plastic part on a corner to avoid touching some internal gears which was the reason of main issue. Now having it or not having it is the same thing. Before when it was installed was making noise and stopping the Play button, so I kind of made things worst. I will try again to test it without this piece and see how it goes. If sound is still not great, I will keep it for my music project and I will install an external potentiometer for the speed so at least will become useful for my artistic purposes. Thanks
