V8 or Polyurethane bushings

[xsteamer]

I couldn't find the previous thread so I am asking what should I buy, V8 or polyurethane bushings? Do I need to use an antiseize agent when I install them?

Poly is the way to go.

And a good policy is: Anti-seize all threads. You may be the next guy to have to disassemble it. /ubbthreads/images/graemlins/wink.gif

Should antiseize be used on all nuts & bolts?

 

[DrEntropy]

I use it on most things threaded. Not many of the engine fasteners: thermostat housing studs are treated with it, crank damper too, but most body/chassis stuff.

Don't use it on lug nuts!

ummm... "most".

We used antiseize on truck lugs for years. If torqued down to proper specs there should be no trouble.

Idle curiousity aroused>>>

Doesn't this affect the torque actually imposed???

I bought those poly bushing for my MGA....haven't installed them yet though, again hopefully I'll get to it this summer....They came with a tube of antiseize

Torque settings are more acurate when the threads are coated with some type of lube. When torquing, you are actually, microscopically, streching the bolt. It might be a bit confusing as we normally think of torque as twist. In bolts, it's actually streach verses friction. The torque can change on the same size bolt depending on its grade and length. Grade 5, grade 8 etc. The friction not being in the threads but from the head of the bolt to it's mating surface. The easer the threads can turn, the more accurate the torque readings. Antisize is a good thread lube because it protects the threads for extended periods of time. Makes it easier to remove the bolt later and it comes in differant heat ranges. Never put antisize on the bolt head or its mating surface. You can use it on lug nut threads as long as you don't get it on the wheel and nut mating surfaces. That's where the friction comes in. /ubbthreads/images/graemlins/hammer.gif PJ
