Markings

[Malky]

Just taking some pics of the standard suspension I have from my 172. The rear springs have a one white spot at the top and one yellow spot at the bottom.

What does this mean? I though non cup rear springs had white/white

Can anyone help?

This could be completely wrong, but some scrapyards put spots of paint on parts when they sell stuff as a way of marking it as coming from them? But i dont think thats the reason in this case.

They're the points at which they're pre-engineered to break after about 5 years. Well... that's where mine broke anyway.

AFAIK, all the 1*2 standard springs have them. Maybe it's where they should be compressed when removing them?
