For lubrication, I recommend to use watch oil. You can buy a pen-like one which will be easier to use. Here is an example:...
Hello and welcome to the forum ! The problem on your D-303 is a worn spindle motor. The motor has play in the bushings to a point where the...
The service manual does not show how to disassmble the unit. Since other AIWA service manuals show this, I must assume it's nothing very specific...
I don't think you need to remove those buttons to take the back cover off. What you will need to do is remove the gumstick battery door, that...
Watched the video. The motor noise seems to go up and down constantly, that isn't right. Personally I would re-oil the motor, but it's to be noted...
Initially I wanted to suggest soldering and I think that can also work. You will need to sand the surface or scratch it well with tweezers for the...
The video is listed as private, I cannot view it. You need to make it unlisted or public in order for it to be viewable by others.
The shaft itself has a slight wiggle ? That should be solid, shouldn't have any play. I can see a small bump on the metal plate it's fitted to,...
It is, but it's not going to last because you won't remove the belt residue/old grease, just mix it with oil enough to drop its viscosity....
First of all, do note that these type of 3 phase brushless motors are more noisy compared to a DC brushed motor. Without hearing a recording of...
The reel gears, in the majority of cases, don't break entirely but just a harline crack in the middle enough to make it not a press-fit anymore....
The reel gears are a very common problem on this mechanism type, but usually it's just a small crack in the center (in which case the gear can be...
Ok, so let's take things one by one: 1. That reel gear is available for sale. I recently spotted someone in China who sells it, unfortunately...
Recently when I wanted to recommend someone the Vapex gumsticks that I use, noticed the first 2 listings that come up upon searching for "Vapex...
Yes, those 2. Thanks for the picture. As for the wires, they're probably soldered directly to components as there's not really much space in...
Given the cell capacity is 500mAh, it's obvious that the 900mAh reffers to the 2.4V output. So the assembly has 2.16Wh. @Rossoe Please share a...
I have seen Rubber Renue on 12voltvids YouTube channel with good initial results (can't comment about long-term results), but I have not used it...
Unfortunately the B602 has a different motor. It's a brushless 3-phase disc motor, while the WM-501 is a normal brushed motor. One of the worst...
Video isn't mine, I just linked it for reference to illustrate how the case is opened. The logic in your steps is correct, only problem is this:...
I open the shell using a thin blade (X-Acto or scalpel) starting from the opening for the head/capstans. In rare cases it can happen that the...
