Smoke it if you got it.................I guess. :shakes head:

While doing my brakes, I had a couple bolts that were fighting me to come off. They are rather corroded. I don't really want to use an anti seize because I know that can screw up the torque rating. Any thoughts on this? What's best to do?

So I was hoping to have my gears installed, but the shop said they can't get the gears to mesh. I have a suspicion that the guy I bought the diff from sold me an Auto diff and called it a manual. :mad:

Does anybody have a picture of an auto differential next to a manual?

Use it. I've never actually torqued those bolts properly and haven't had any issues. Probably not the brightest, but if you use anti-seize and torque them, then I personally don't see an issue. You might need to set your wrench slightly under the rated value.

But then again, I may be full of complete crap and you can ignore everything I've stated. :wtf2:

Disclaimer?

Your options.
1. Reuse bolt as is.
2. Chase the threads with a die to clean up.
3. Use a little bit of anti-seize to help the thread.
4. Get a new bolt.

I've done all 4 at one point or another in my life. :rofl2:
What is the bolt for? Caliper bracket to knuckle?
If that is what the bolt is for. And by looking at the head of the bolt. The flank of the face doesn't look to healthy. So I would pick option 4. Because of the flank starting to round off.But I don't know what the rest of the head looks like.

Finished up my sub box project!
Did a build log here: http://www.the370z.com/audio-video/1...build-log.html

Only Bolt's that received any loc-tite are in the diff,,,all other's have anti-seize-as i often check for tightness & don't like seeing threads like those posted.

Get four new ones. You will thank yourself in the long run!!:tup:

:iagree:

Clean it up with a wire brush or tap and die. Apply blue thread locker. It will hinder further corrosion.

I'll get new ones. I see a 6 on the bolt head. Are these hardened? I know usually the hardened bolts have lines on them.

Metric fastener grading is a little different. 5.6, 8.8, etc. I'm not certain about this specific bolt, but I'd suspect it would be case hardened.

I got 8.8 and a tap.

Hmm... looks like one of my rotors is warped a bit. Question is... to go oem, slotted, drilled, both? Any advantages/ disadvantages?

It's not a metric bolt though. 1/2"-20
Edit: nm... you said metric grading.

I've read that drilling rotors is more harmful than beneficial... I'd say if you don't track then go with cheap auto-parts OE replacements.

Well actually. The picth appears to be the same on these things, but the bolt itself is about half a millimeter wider. These aren't going to work.

Looked at it for the first time in two weeks. Contemplating driving it to run a few errands. TBD.

12 mm with a 1.25 pitch. They didn't have any hardened metric bolts so I'll just tap and die this out and hope for the best.

This looks better.

:iagree::tup:

Same tap and die for our studs and lug nuts. I might as well clean those up while I'm at it.

I was thinking it's was a bit odd to have a standard fastener on a modern car. Particularly one of Asian origins.

Yeah, that was my thought as well. But apparently, an M12 1.25 bolt will thread intro a 1/2"-20 nut... just not the other way around.

Installed a new XS Power battery today.

Was 50 degrees here in NYC so I did a vac, wash, clay, compound, and wax... didn't polish, clean the glass, and add sealant because I'm getting old and lazy. Will probably get to it on my next day off.

Up early; as I didn’t get phoned in to work,,,So headed to the Dragstrip for a few passes this afternoon-gonna give my Baby a Bath!
Weather is going to be good; humidity a tad high...but glad to get out there!https://uploads.tapatalk-cdn.com/201...946ad0da17.jpg

I spent some money on some much needed safety equipment, to go along with the seat i picked up the other day.

Looks good. :tup:

******* passenger side catalytic converter came loose apparently :mad: not looking forward to fixing that

Had a beautiful day to waste, so the wife and I had a wash party. https://uploads.tapatalk-cdn.com/201...90f2f46e89.jpghttps://uploads.tapatalk-cdn.com/201...967393cb17.jpg

That should be a 12mm x either 1.25 or 1.50 thread pitch. The car is metric, so a 1/2" - 20 would be totally wrong.

See if some store has a thread pitch gauge and get one in metric & SAE. It will save accidentally destroying a bolt... :ugh2:

What battery did you go with?

Drove it hard for nearly 30 minutes trying to forget about the busted pipe in my foundation leaking into the house. It worked as long as I was teetering on the brink of traction. Unfortunately there was too much traffic to really push that threshold on public roads and fuel starve continues to be an issue with over 1/2 tank of gas :shakes head:

Time to give phunk a call. :tup:

:iagree:

There are several CJM products I have on the list. But that RRP kit definitely falls into the category of necessary upgrade now that the Z is no longer my daily :driving:

Unfortunately, I'm probably looking at spending a hefty chunk of change on a plumber in the coming days to fix a slab leak :thumbsdown:
