I'm putting on my Alcoa wheels,(Bus is jacked up as I'm typing this) Everyone around these tire shops are telling me different torques for the lug nuts. Can anyone tell me? Thanks |

Type in " ALCOA BUS WHEEL NUT TORQUE " in the search area on your internet browser.....The service manual from Alcoa is there... you should find it with a little bit of searching the site choices.... took me about 2 minutes. I would give you the stated torque specs, but there different ones for dry or oiled studs and one or two piece designs. |

So, JTNG
From that article did you gather that the maintenance guys are way overtorquing the wheels, causing the studs to break, and that really ugly internal politics are at work with Mrs White fighting to keep "her troops" in control & her husband out of trouble?
That's what I read.
In my opinion, it does not change the fact that there are tens of thousands of steel inside/aluminum outer wheel combinations runnig the roads every day. By the article's own admission, there's only been one case of a bus losing a wheel anywhere in the U.S. in three years. |

Who're you, the ghost of threads past?
(go read my last post on that previous thread, willya' ?)
My post here was to provide some info pertaining to over-torquing
the lug nuts... something I didn't give much thought to, as the
young guy at the tire shop put my duals on... I'll have to invest
in a decent torque wrench and get a long pipe to check the wheels..
I'd wager that there are plenty of guys like me (gals too), that
leave the mounting of tires to the garage and don't check the
torque themselves (or re-torque), afterwards. That article
was an eye opener. |

I wonder how they determined the tightness of the lug nuts. Did they see how much it would take to tighten further or see how much it would take to start to loosen? Did you notice the web site ads for tire/ wheel related items at the end of the article? Hmmmmm? I invested in an accurate torque wrench after my father used to tighten his wheel nuts with a pipe on the breaker bar. they were way too tight!btw.. You shouldn't use anti-seize either as over time, it dries out and will start building up in the root of the threads. |

Hello busnuts.
Proper wheel installation techniques do not include using the air gun to install fasteners, and do not include using anti-seize on the threads of the studs.
MTA will have to crack down hard on their people to use the proper torque wrenches, have them calibrated regularly according to manufacturers recommendations, and replace the studs on their entire fleet.
A stud that has been abused by over-torquing cannot be trusted to hold the proper ~500 lbs of torque.
From all of this, Busnuts need to wonder about their own studs.
INVESTING in a fresh set of studs for our bus conversions would be money well spent, because we have no way of knowing whether our studs have been similiarly treated prior to our ownership.
happy coaching!

Absolutely excellent point, Buswarrior!!
None of us have any idea what our bus has been through. The
last thing any of us consider, are the wheel fasteners. We have
no way of knowing how they were torqued, or if they were
ever over-torqued! Replacing them all, wouldn't be a bad
idea at all! And having a torque wrench handy for the use
of the installer, would be money well spent!
What's needed here now, are good suggestions for torque
wrenches that will do the job! |

We had a torque stick ,basicly an extention for the impact wrench that limited torque to 400 ft/lbs and it worked with any 1 in impact |

So Chuck, we infer, rather than state "inane" and "smartalecky" That's like volunteering to the little woman in your life "I'm not the one that said you were fat!" LOL!!!
Dear L Jensen
What was your recommended torque, and what, if anything, did you do to assure that the studs were properly torqued once you "theoretically" got them to about 400 ft.lbs. with your device? |

The torque sticks come in different ratings and one can be purchased for the torque of our wheels. Recommended by many trucking publications. Can be purchased at any truck parts dealer. I'll check if NAPA can get them. |

Best thing is BUY a quality torque wrench!! you can still OVERTORQUE with a torque stick and air wrench unless the stick breaks at the proper torque! |
