You know, I'd noticed the tinks had died back yesterday and today, didn't connect it with increased temps. It's actually been quite nice the last two days.I noticed that after the first real hot day here in the NW, and the black SSR setting in the sun all day, I didn't here any tinks or that rattle I've been hunting.
It rained today, and THEY ARE BAAAAACK!
Your ride sounds like a hoot and a half.
Ok, So heat means parts are expanding, some parts expand more than others.
alum 24 x 10 -6 in/in/deg
steel 12 x 10 -6 in/in/deg
So, the drive line is ~54" and and given a temperature shift of 30 deg:
Then the drive line will grow by 54*24*.00001*30= .388 inches
While the steel truck grows by half that much or .194 inches
That's a little more than 3/16 of and inch difference. More than I expected.
The question becomes, How does 30 deg. temp swing and a 3/16 inch difference in length make the tink go away?
another source says that the coefficients are
12.3 x 10 -6 in/in/deg for alum
7.3 x 10 -6 in/in/deg for steel
