Sir Wally, I think you got hijacked I'm going to fly the plane a bit more towards Cuba before returning control...

FYI - WSM p44-19.

One item for the consideration by the Spelling Police. I think "calotte" is an example of Germlish that has crept into the manual?

See:
http://dictionary.reference.com/browse/calotte
and
http://dictionary.reference.com/browse/collet

Also, does anyone (except Doc Brown of course ) use only Special Tool P 300 to remove the lug nuts? (Which seem to be aluminum and not - as I thought - magnesium?)

Does Optimoly TA contain graphite? I cannot find a data sheet on Castrol's site.

To re-open old threads on what paste to use where...

and providing the following links for reference:
http://depacproducts.net/anti.html
http://www.sacskyranch.com/antiseize.htm

Nickel-based anti-seize seems to be the paste of choice except for where zinc-based paste is need with steel and aluminum. Copper-based cannot be used with stainless steel and Aluminum cannot be used with carbon steel. (?)

In some old thread 'round here, someone who seem to know, suggested that copper-based shouldn't be used where it might come into contact with coolant.

ARG!... Ok.... returning the controls now.

WSM 44-19 states that "threads and calotte<sic?>" should be lubricated with Optimoly TA.

Tony

same thoughts....insightful though.

My wheels are on and off enough anyway..but i just use a dab of that stuff that permatex sells....the Silver smelly stuff that no matter how hard you try you WILL wake up with some on your pillow in the AM some how Is that the right stuff or not?

SharkSkin

I have always used Permatex Anti-Seize on lugnuts... motorcycle parts... hell, even on my bicycle axles when I was a kid. I've learned more since then and am more discerning these days, with copper & nickel anti-seize compounds to use as called for. I've never had a lugnut, steel or aluminum, strip or gall -- but I've seen many, many problems on other people's cars where lugnuts are installed dry -- especially in the early 80's where I was changing tires all the time working for AAA.

Note to self -- If Jason ever sells his shark, warn the new owner about lubing the lugnuts.

BTW Jason, what's up with that sig? Something about how the R8 sucks for drifting?

Mrmerlin

Jason its Illegal not to lube your nuts. Lube it up man!

Larry Velk

The smell of the silver stuff is probably mercaptan (sp?), possibly a trade name rather than an official chemical name. Used in natural gas as a warning smell to indicate its presence. I was told by a journeyman steamfitter - they use pipe dope with this material - that it is an emulsifier; it is put in the dope to keep the particles in suspension.

iDoc

You guys ever heard of using an antacid like Maalox as an anti-seize?

Bill Ball

FYI, throughout this message thread, Optimoly TA was mentioned as the factory lug nut lubricant. I couldn't find anything in the WSM about that. This bulletin says Optimoly HT, which is copper-based, applied to the shoulder as well as the threads for aluminum lug nuts. I couldn't find anyhting later that superceded this bulletin.

Bill, adding to the collective confusion and from my previous message 44-19 (printed in 1988) contains the reference:

MGW-Fla

I spent the better part of this past Sunday playing one man pit crew on our two sharks, switching out between a rotation of three sets of wheels to get ready for our Sebring Shark Shiver this coming weekend. That included washing each of twelve wheels inside & out.

I used the silver Permetex high temp anti-seize that I have on the threads, but Ahhggggg!!! I didn't lube my "calottes"!!

I did however remember to take my regular intervals of the max # of Ibuprofen to limit my back from reminding me of just how old I really am!!

hacker-pschorr

We keep looking at the 928 WSM. Does anyone have a 993 manual from 96-97 handy? Same lugs.

hacker-pschorr

What about those of us who use steel lug nuts

ew928

Ask my ex-Audi about how steel and Aluminum bond after being in close contact like fingers and Super-Glue. The AL rear wheels would just NOT want to leave the brake disc surface.

I'd anti-seize the collet of the steel nut. But that's just me.

cobalt

I have been doing the same for 25 plus years of using aluminum lug nuts on numerous different Porsche's, not once have I had an issue.

SharkSkin

5 years using the hi-temp Permatex anti-seize. The combination of anodized nuts on chrome may not be applicable to everyone, but IMHO it works fine.

BC

I guess I install and remove my wheels enough to never have a problem.
