Why waste your time trying to tighten compressor bolts , they dont come loose and on the newer machines theres no O ring in there anyway , all you are concerned about is the flat gasket joints.:payattention:
Well that was a waste of half of a night :gah: , but the important thing is that I learned something , I guess I need to pay better attention , point well taken .:whistle:thanks for all of your post your time and expertise is muchly appreciated . :grin2:
When the sealant they use on the metal to metal flanges is still wet, I apply final torque within an hour of putting the flanges together. The number is not as important as having even surface tension on the flange all the way around. All of the compressor bolts are 5/8" grade 5. The torque spec for them is 120-165 ft./lbs. The most important thing to take into consideration when you're trying to evenly torque the bolts is how clean the threads of the casting and the bolts are. If I can't easily thread every bolt into every hole by hand almost all the way with a tiny amount of never-seize on the tip, they're not clean enough, in my mind, to get a consistent torque on the flange. If the bolts give resistance, they'll make your wrench "click" prematurely. The sealant used at the factory hardens from the inside out, and once it's hard, the bolts will not come loose. If you have a leak on a compressor flange, you have to take it apart to fix it right. No shortcuts, unfortunately. One thing I can tell you is don't put 30-35# on the econo bolts. In my experience, the 14-16# factory spec can even be too much. I've gotten used to going by feel and sight on rubber gaskets. If the gasket is pushing out of the flange, it's too tight.
Thank for the great info Rob , I appreciate your time and expertise , cheers!!
A recent conversation between myself and one of my colleagues went like this:
"How do know what an inch is? How can you precisely measure it?"
"I don't know, with a micrometer?"
"No, just look down when you pee"
"I'd have to look down and then divide by 12"
No problem, Troy!
