Torque Wrenches and Actual Torque Applied

[c3powil]

Hi guys

Recently this video came up in my Youtube feed:




I thought it was pretty interesting, and validating of my own Harbor Freight Pittsburgh Torque wrench that I've owned for probably a decade now.

The most interesting thing I found was how torque readings are skewed when applying anti-seize. Since I know Loctite is applied liberally to all Buell XB models, and probably more, I thought I'd pass along this video for any of you who may find it useful.

Yeah, you have to pay attention to to more than just the torque value when following a spec, with or with out loctite, if your'e supposed to oil the threads, etc are all big details.

And... just confirmed my 1/2in torque wench is off in space for reverse. I need to find a new one to keep with the Buell.

Also, if you want a quick laugh, hit up Tractor Supply's website and search for 'torque wrench' to see what comes up.

The impact drivers listed as wrenches?

"Three ugga duggas for anything larger than M4 thread should be good, right?"

Nice vid and thanks for posting

PS-Still have my 1971 Sears beam-style torque wrench Dad and I bought new to torque the rod caps and such on the 66 VW van we rebuilt back then. Remains fully functional and cosmetically pristine along with being deadly accurate +/- 30% or so.

I feel like this is every PO of every bike I have ever owned.

I gotta look for one of those next time I stumble upon a yard/estate sale with a lot of tools.

So, I'm assuming that all the torque listings in the shop manual for my Buell is for dry threads. I was shocked at the results for using Anti-Seize.

Calibration checked every year and to my knowledge it’s never needed adjustment. I use dang near daily!

Incorrect assumption. Many XB fasteners are torqued to SM specs with either A/M permanent or proprietary thread locker.
Front primary sprocket nut...front drive pulley nut...front fender torx...to name just a few.

 

[miatamarty]

Pardon my ignorance but what is SM specs and A/M thread locker? Loctite? All these abbreviations leave me baffled.

 

[Kurlon]

Service Manual, and I think A is for anaerobic thread locker, aka loctite vs some bolts that call for motor oil being M?

 

[Barrett]

Marty: SM is service manual....A/M is aftermarket recommended thread lockers.

Many OEM replacement hardware bits such as engine and trans and primary nuts come with captive proprietary thread locker already installed. Other bits such as fender torx screws...airbox base-plate torx screws....caliper mounting bolts all use recommended thread locker. That liquid is proprietary from the factory and never available to the public. Simply use blue Loctite during reassembly of those particular fasteners and red for engine/trans/primary nuts. Does NOT affect any recommended torque settings.

Thanks for the heads up. I'm very familiar with various types of liquid thread lockers. I retired a few years ago from being a shop owner for 35 years. Any questions about Japanese trucks or SUV's just fire away.
