Hardware Oldies Famicom Disk System Alignment Assistance

[Gallaer]

I recently got a Famicom Disk System and managed to successfully replace the belt. However I'm running into the common errors of 22, 23, 27, and 28. It's just the calibration of the spindel which seems to be off. Anyone have any tips to get it aligned properly? Also what is the exact size for the spindel's allen key?

Have you tried cleaning the drive head with isopropyl alcohol and Q-Tips?

Don't know much about FDS alignment (hopefully there are some timing marks or maybe something electrical, or at least few enough options to brute force a solution). Don't have time to go through the 3 part series on repairing the things but it looks annoying even by things powered by rubber bands standards.

Allen key wise then most things from Japan will likely be metric -- Japan might have special screws (see JIS cross head which many mistake for other forms/many people working on Japanese cars and motorbikes end up with a dedicated set) but the legacy of mr allen (one of history's greatest villains as far as I am concerned) goes unhindered there. If you have a basic import cheap Chinese crap type shop around you I usually see them feature a little roll up holder full of metric (half and .2 mm increments where appropriate) and imperial, and if you have to go one further down the line to the keyring with springs holding things on then small metric versions of those exist too. Better yet if it is a bit bashed up the next imperial or metric size might do the trick.

Once you've repaired your FDS, its a good idea to install a write-enable mod so that you can use the FDSStick to make copies of your existing games and even write your own. https://gbatemp.net/threads/fds-3206-write-enable-mod-for-the-famicom-disk-system.635324/

Yes I have, cleaned the whole thing. Left the grease though around the posts.

Also thanks. I'll look into it.

I got the correct size Allen key, It's a 1.5 (Metric). So, I tried readjusting everything and it's more consistent now. The disc tries to load, it goes into a black screen which usually has the Nintendo information and everything but it never shows up then throws error 27. Which is the spindle calibration error. I'm not sure what I'm doing incorrectly.
