    The importance of torque values

    Soooooooo, I changed the final drive oil just now and when I unscrewed the fill cap, I thought it was way to loose. So after fill up, I tightened it a teensy weeny bit more and SNAP!!!!

    I beheaded the cap but was able to unscrew the lifeless thread still stuck inside thank god!. I̶ ̶l̶o̶o̶k̶e̶d̶ ̶u̶p̶ ̶t̶h̶e̶ ̶t̶o̶r̶q̶u̶e̶ ̶v̶a̶l̶u̶e̶ ̶a̶f̶t̶e̶r̶w̶a̶r̶d̶s̶ ̶a̶n̶d̶ ̶ I saw that the torque value was only 8nm, which I find odd for such a large bolt and fairly important function, but oh well...

    Damage costs: €32,18 for a freaking bolt excl. O ring... I can pick it up tommorow if the order is processed today, so fingers crossed.

    Can anyone recommend an affordable and reliable brand of torque wrenches? I never looked into these things but no way I'm doing this in the near future without one... Most of the ones I saw at any hardware store are well over 60,- which I find ridiculously expensive for a once a year usage.

    if you change your engine oil yourself you could use the torque wrench    it would be cheaper than a stripped drain plug       also the diff plugs are made of cheese

    Hello CT_Ron,

    I did a little research on this one last year, and read quite a few reviews. You can spend ridiculous amounts on torque wrenches of varying types and sizes etc.

    I found that the Halford's brand are quite good and generally, well reviewed - still not cheap though !

    I ended up with the 12 - 100Nm 3/8" drive option at £85 (convinced the other half to get it as a Birthday/Christmas present  :152:) !!!

    Bye for now.

    Wack

    I did exactly the same thing Ron, the day before a 10 day tour. Luckily I found a bolt in the workshop with the same thread. After a bit of welding and machining I ended up with a replacement that will never break. I now use a torque wrench on it every time as I don't want to strip the thread in the final drive. I bought a new cap and O ring, which should be made of gold for the price charged, it's still in the packet. I wonder if it's designed so weakly to protect the thread in the final drive, a bit like a shear bolt used in other applications.

    I'm very curious, do you have a picture of it?

    I too think it is designed to break easily. It broke like breaking a kitkat candy bar, it went so easy... And the thread left inside, I was able to unscrew using my finger and I had no damage to the thread inside, as if it was designed to do so like a fail safe. I can not explain in words how tense I felt yesterday screwing in the new bolt, which indeed is made of 24k gold... But I'm glad I had a new one within 24hr.

    A life lesson learned: Read the manual.

    Thanks Wack! I'm still very suspicious towards these wrenches. I read a lot of people complaining that the values have too much deviation. The cheaper, the worse. I need them for precision values like those oil drain screws but also my rear wheel bolts which are over 100nm. I dont want to spend €120,- but I know I might destroy a thread or bolt something down too loose with a cheaper one..

    My birthday is in december but my wedding in July, so... tools it is ^_^.

    Aldi did a cheap torque wrench. I'm not saying it's super accurate but not let me down yet.

    Tend to set under rather than over just in case

    I don't do enough mechanics to pay big money or have one regularly calibrated.

    Faulty drain plug from manufacturer??

    or have Honda learned most stealerships let the YTS yoof do oil changes and the subsequent carnage that involves
