Where is everyone #5

That's just cruel and unusual punishment right there.
Remind me not to piss you off...

 

I was talking about the general theory of how the system works. Spring tension ( any spring. No matter what it's used for. ) is dependent on the material it's made from, the number of turns, the space between turns and the inner and outer circumference of the size of the finished piece. Like you used to see double valve springs in Race gasoline engines ? I believe that those have been superseded ( ? ) by improvements in metallurgy. The two were different sizes ( obviously since one fit inside the other ) and were made from different types of material to do different jobs while working together on a common goal. Lots of different things to work around and compromise on. Harmonic vibrations would lead to failures when they just tried to make bigger, thicker valve springs. Bigger and thicker would have problems with compressability and eventually would lead to worn down cam lobes, early failures and sometimes even broken camshafts.
Spring design is a specialized field of engineering. I read a short article about it. I'm not an expert. I might have possibly read that from the writer in Cycle World magazine ? Kevin Cameron ? I don't remember where I read about it but it was well written and researched. ( Which is why I think it might have been Kevin Cameron. Very smart and good writer. )

I have NO idea about the technical details of that particular brake chamber. Sorry if I wrote it misleadingly.

If ( Big IF ) that spring is the same part number as one that goes in a different size brake chamber, THEN it will exert the same pressure in both. Or at least will have the same amount of available pressure. Like a battery has a certain available amount of CCA ( cold cranking amps ) . It doesn't force that amount into the electric starter EVERY time, it only provides what the starter draws from it ..... up to the maximum amount that it has ( which, in theory is it's CCA number ).

It's like a bucket of water to get dipped out of. Bigger dipper equals a bigger gulp of water. Up to a dipper that's the same size as the bucket. At which point it runs out of water.

Ha! I'm old but smart. I ain't moving nothing bigger than a 336. On 5 axles! You kids can have the "glory "

 

Enlighten me on the use of turbo blankets and exhaust wrap please. I haven't used them. @superhauler does though I think.

The exhaust cools down slower and thus moves through the exhaust easier or faster?

 

sacrilege !

 

The brake chamber numbers are based on the size of the chambers. The first two are the service brake side and last two are for the parking side. So in @johndeere4020 case he has "extra" force related to the parking brake side which is probably good for the weight he drags around and the off-road parking situations.

 

Santa's gonna hear about this B.

 

It picked the right day!! Y'all get up to 50° today?

 

I wish I'd seen this before I sent that text to Santa. Now I'll have to send him another one. Looks like no new chrome for you next Christmas mister.

 

I understand your theory, but in this situation the 36 square inch side pushes back the parking brake. Why use a bigger diaphragm to push back the same spring? Seems to me it’s a stronger spring for better holding power therefore requiring a larger surface area diaphragm to compress it.
