Blog: by Shane Conley Video Lesson: Torque wrench extensions andbolt stretch proof.

Every fall I start the technician training program with a safety class and then diveinto an in-depth curriculum on fasteners. Sounds pretty basic for gearheadswanting to learn how to wrench on motorcycles right? Would you expect I getthose blank faces and boredom sinking in? You could have bet the bank on it forthe first few years I taught. What a struggle it was to get these students willing tocheck their own understanding against possible new information! I’ve told youmany times teaching isn’t easy!

You see the desire of a passionate teacher (coach) is to help you avoid thosecostly mistakes we learned the hard way. When you think you know it all about asubject or that the information is to “simple a child gets it”, you will most likelyshut off your learning door in the brain and tune it out, waiting for the time to pass.What to do?

Make it fun! Make it impactful, entertaining, and prove it. Ok, now we are gettingsomewhere. In 2007 I started by collecting broken, stretched, and damagedfasteners. In 2010 I added a lab where we actually stretch bolts by over torquingthem, measuring and recording each step until failure. The results were all overthe board which drove home how many fasteners are being previously over-torqued by techs. Many students find that the fasteners would fail extremely closeto the required spec for torque. For example; a bolt with a tq spec of 12 ft-lbswould stretch at 13 and break at 16! This was an opportunity to teach threadrepair and helicoils, taps, and die usage. The students did not all agree this wasan opportunity. What? You get to break and repair on something that doesn’tmatter for free and you can’t see the gift? UGGGGG….they would then say, “wellI’m never going to torque to full torque again”. OH NO, WE ARE GOINGBACKWARDS NOW! This is the critical understanding piece here. LISTEN, PAYATTENTION…STAY FOCUSED>>>>>>>>YOU MUST UNDERSTAND THIS!When working on ANY installed fastener, you’re following the last tech, calibrated(or not) tools, untrained tech, DIY tech, and craftsman.

Enter 2012 and we now have this SnapOn torque wrench testing tool. You canbet Coach Conley was already planning new labs and methods of proving them!This tool simply revolutionized the ability to speed the learning curve and drivehome the best practices when dealing with fasteners! After 10 years of teachingand I’m finally feeling like I have this curriculum dialed in. If I was training under aSnapOn Torque Certification Program instructor, you could bet the bank on melearning something new. If only I could talk SnapOn to sponsoring me to trainunder them in this program! Hint Hint Mr SnapOn…

In summary, no matter how much you think you “know”, don’t turn that “listening”part of your brain off. You may just be surprised and what you’ve never thoughtof. And when dealing with fasteners, you have no control except to practice anduse these demonstrated skill-sets.

▪ Use a service manual for your year/make/model your working on▪ Use quality tools and have them calibrated over time▪ Protect the tool from being dropped or damaged by chemicals▪ Inspect the fasteners you remove▪ Clean fasteners, threads and PREPARE for installation▪ Uses required oil or thread locking agents as specified▪ Here’s the big one…PRACTICE your FEEL for what bolt stretch is▪ Bonus Tip: practice on something junk not the customer’s vehicle
