anti seize question

Re: anti seize question

How do you know by how much to adjust the torque spec to allow for the lubricity of the anti-seize?

Jim

You don't, although you can probably use the low end of the range, if the torque spec is a range rather than a single value.

Most GM wheel nuts of the era are speced at 80 lb-ft, which is what I use, and they always torque up nice and smooth and consistent and the same on breakaway.

Especially if you have multiple sets of wheels and tires, like I have for my cars and swap them frequently, anti-seize will save everything from galling damage.

Here's a bit of info on lubed/dry bolt torque/load. I'll let ya'll add the coefficient of friction factor. (steel, lubed/dry)

Some pretty amazing clamping loads.

The wheel lug nut torque for most 63-67 Corvettes was around 50-60.

torque on aluminum wheels is 100# ft

Re: anti seize question

torque on aluminum wheels is 100# ft

Is that for C6 Clem?

The Corvette Service Manual page 3-81 states 100 lb ft.

For what year? Not 63-67.

97 up and i did not ever see a 63-67 corvette with aluminum wheels back in the my 63-67 days. i think you need the 100# ft on "real" aluminum wheels because of the expansion and contraction due to heat on the new aluminum wheels where the nuts hold the wheels.

Looks like they increased the torque for the newer cars. I think all 63-67's were around 50-60 lb ft but it was raised to around 80 lbs for the 70's cars?

I think 67 with aluminum wheels were also 50-60?

Re: anti seize question

The '63 ASM does list 55-65 lb-ft.

Re: anti seize question

67 Chevy Service Manual, section 10-4 "Wheels and Tires", paragraph "Change (W/Wheels)" states:"Proper torque on nuts is 55-75 ft. lbs.(75-85 ft. lbs. for Corvette aluminum wheel nuts." not 55-65 or 100 or other values as some have opined.

The 63 AIM calls for 55-65 ft lbs. (ok, I missed it by 5 lbs)

The 66 service manual shows 55-65 ft lbs.

Michael -

All 67's, both steel and N89 aluminum bolt-on wheels, used the same lug nuts, and torque was 55-75 ft-lbs.

Thanks John. That must be the year for the new longer stud?

Michael -

Dunno for sure - P&A shows they went from the 1-3/8" stud to the 1-3/4" stud in '65.
