What is the proper Torquing method?

When torquing head bolts or wheels, what is the correct method? Does one torque them once in the proper sequence, or does one go back and repeat the sequence until further movement of the nut or bolt is not achieved at the called for setting?

Thanks in advance.

Matt

I torque them in the proper sequence, and then go over that sequence again just to make sure.

What's the proper torque for the wheel lugs again?

I think that it is 75 ft/lbs. I took off snow tires off my Outback and Ford Aerostar (100 ft/lbs) this weekend, and noticed that I could tighten the regular wheels more by re-torquing, which is why I asked the question.

Could you torque them more immediately, or do you mean you tried before you took them off?

This may be unrelated, but I learned from the guys at the tire shop this weekend that you should retorque the lugs after driving 100 miles or so. So that would follow that they loosen a bit after getting "broke in"?

The correct answer for Subaru headbolts is to torque them, back them off, then re-torque them. Funky procedure for a guy used to domestic "bent iron" (for you Harvey )

torque

Hi SVX people, From the owners manual for 1992. Wheel nuts:72-87 ft-lb. I like to tighten in a star pattern and as Nick said , tighten once at proper torq and then retorq. And yes you should retorq aftr 100-150 mi. My understanding of torqing heads is to start in the middle and work your way out in a spiral., but this may vary by brand. BOBB

torquing head bolts is very specific, just follow exactly what it says in the manual.
Wheel bolts come in 2 types, flat washer style and cone/cup style.
Since I haven't taken the SVX wheel off yet I'll give you rules for both.
Flat washer style: Torque all to half spec, order isn't teribly important. then retorque at full minus 10FtLbs, then full spec torque in a star pattern twice.
Cone/Cup Style: usually used on steel rims. Torque to full spec minus 10FtLbs in star pattern, torque to full spec in star pattern twice.

Retorquing after 100-150 miles??? NOT. don't need to do this. If you retorque a wheel for any reason, make sure it has cooled down completely.
Never trust your airgun's torque spec.


FYI, the wheel torquing on the SVX has proven to be very sensitive. make sure you torque all bolts equally.

Hey Todd,
You make it sound sooooo easy. I read the torque procedure for the SVX heads and said "what?" more than a few times. It is lengthy, long and complicated. In my opinion. They use the 'flat method" or degrees to be turned in stead of a torque valve. This is more accurate than a torque wrench when done properly.

I think it works great as head gaskets leaks are far and few between on the SVX.

True John, but how many people here (other than a select few ) are ever going to remove their cylinder heads?

I would expect that very few SVX owners will get a chance to torque their h-6 heads. But for those who do, I would suspect they will have a manual to work from. And if they do not, let the SVX God's have mercy on their souls. Or horseshoes up their a$$.
