Don't know if these retainers are available elsewhere. On that site you need a proxy to buy and a plugin to translate the descriptions in English....
Another thing I should mention is belt can be slipping on some of these Alpha-2 mechanisms. While the original belt is usually still good,...
Yes it will raise the gear on that end, that's what we want in order to increase the clearance. In theory using a washer on opposite end should...
For lubrication use watch oil, the one in the link is fine. And where grease is needed (like the pulley arm) Molykote EM-30L. Yes, this is a...
Have you checked the tilt angle of the head and rollers ? Remove the door and one of the 2 cassette holders and check visually from one side....

There aren't many point to lubricate in this mechanism: - motor bearing (in WM-10), however getting oil past the seal can be difficult; - table...
This tutorial covers the adjustment of middle pulley in WM-10/20/30/WM-W800 mechanism. In these mechanisms the middle pulley sits at an angle when...
SX1V is a newer generation without the pad lifter and associated problems (too high roller pressure). While the newer AR90 IV mechanism is more...
This WM-100/200 series mechanism is a bit unique regarding the pinch roller engagement: there are 2 pins for each roller. When mechanism is...
Your rewind problem is not mechanical, it's the auto-off circuit that shuts the motor off. Things to check are voltages around Q308, 309, 310....
The mechanical noise is typical of this mechanism, those loud bangs are the solenoids engaging and that's the typical sound even when it works....
Stated before the motor and caps are a known issue on this model. The caps need to be replaced, see the link in post #19 for details. While they...
@Timo The microcontroller needs to initialize (engage FWD, REV, STOP) before any input from the buttons will work. What happens when battery is...
What happens if you remove R305 from the circuit ? What about the power LED, does it remain on even after 1 press ?
I agree with @novrain2012 that it's more likely problem is caused by a cracked trace or open via rather than faulty transistors. Would add it's...
Left VU-meter acts as battery level check (see the green marking), that's why only the left needle moves.
This only happens when powered via DC in jack, not with batteries ? That 320mA current draw being exactly the same when on and off, but nothing...
