1981 AIWA MINI COMPONENT SYSTEM

ANOTHER DUMP FIND. IT ALL WORKS OK BUT THE SWITCHES NEED A GOOD CLEAN AND SO DOES THE FACE PLATES..NOW THE PROBLEM. I CAN'T REMOVE THE VOLUME DIAL NOR THE TUNER ONE. THEY ARE STUCK SOLID. THEY WILL CRACK IF I FORCE THEM. AS I COULD SEE THE PLASTIC BENDING WHEN I TRIED. DON'T KNOW WHY THEY ARE STUCK ON SO TIGHT..ANY IDEA HOW TO REMOVE THEM SAFELY

Try with (or make out of sheet metal) something like this to get the knob base moving from the shaft. Checked if there is any screw holding it?

Are the knobs a solid single piece construction?
I`ve seen some types where the front disc just sticks on top of the main knob which reveals a securing screw when taken off.
A bit difficult to tell in the photo`s if a metal front disc has be secured onto the main knob which may be plastic?.
If you can trace a service manual online it might have some exploded diagrams that give a hint.
Good luck.

the knobs are a solid single piece of plastic..there is no front disc that comes off..i know what you mean ive removed knobs like that before

 

[JVC Floyd]

have you tried removing the top cover and looking at the knob from behind inside the unit.

Hi Wes125 ..I put "aiwa sa-c22 specs" into Google and came up with a few sites which have free access to download a repair exploded pdf.
I`m not brilliant at understanding these but by having a quick look it seems the knobs might possibly be on a screw thread rather than a simple push fit which is more common...might just be the shading on the diagram though so have a search and see what you think.

Demonfinder i can see by this pic they push on. i thought they did. i cant understand why they are so tight. not unless the plastic has welded itself to the spline

Try using a heat gun on it. By the way I can't believe someone would be stupid enough to throw that away, especially when it was still working.

Reli. most of my retro stereos have come from the recycling centres here in the uk..there will be further post on what i've bought

2 small spoons facing inwards (equal pressure), wedge and pull; they'll come off.

Use a piece of string. You don't want to damage the face plate.

Tape off everything with green Frog Painters tape, use plastic tools, never metal, just like the car guys do. Heat will probably destroy the screen printing since some of these come with a metal knobs and need higher temps to "crack" them.
