Low Torque Torque Wrench

Discussion in 'Technical Help' started by noobie, Jun 17, 2019.

  1. Not bike but car

    My qualified main dealer tech friend fitted a new gasket on the old focus, despite me telling him the torques of 2 newtons outward on the first circle and 7 newtons on the second cycle outwards, he grabbed hold of a normal socket set and wrenched it. Result, cracked plastic rocker cover and new one from ford coming from Germany (yes I know there are cheaper second hand ones but no guarantee's it won't be damaged)

    So, aware I can do it myself and looking for a torque wrench, most seem to be 10/20 newtons and upwards.

    Have you used a low level (sub 10 nms) torque wrench and if so, any recommendations?
     
  2. you dont need a torque wrench for that. just a 1/4 drive socket set.

    but limited between 3 and 15Nm

    Or just lightly by hand...

  6. I've had the same two torque wrenches since for ever ,
    both are made by Norbar , and both are excellent .

    The high range wrench goes from about 30 Nm to 240 Nm ,
    and anything higher than that is very tight indeed .
    Example : Clutch center ( hub ) nut needs about 190 Nm
    ...... same for the alternator rotor nut

    The low range wrench goes from maybe 8 Nm to around 40 Nm
    Anything less than that , for me , I would describe as "snug "
    or about as tight as you get with gentle hand pressure
    using a small T-bar , or a screwdriver handle for sockets .
    Example : anything involving plastic parts , such as fairing screws
    into " well-nuts "

    The lowest value I ever saw specified in a Ducati manual was about 8 Nm
    and for comparison hydraulic bleed nipples are specified as 12 Nm

  7. Now that really IS low .
    The only time I ever used something that low was in an electronics
    factory when large power transistors were screwed to aluminium heatsinks

    Don’t know why I bought it must of been when I rebuilt the rgv 5nm to 25

  9. For precision when tightening screws with preset torques of 1.0 to 5.0 Nm.

    2 - 10-Nm torque wrench (got this one its the bees-knees)

  13. I was at my dentist the other day getting an implant. He said we torque the titanium plug into the jawbone to 70 newtons.... :eek:
    I was thinking Scania wheel nuts and envisaged my skull cracking in two :scream: until he told me newton centimetres...
    Phew!!

  14. I don't know about you, but that tightening is the worst fucking sensation I have ever had in my life... :confounded:
     
  15. I have a Snap-On electric torque wrench. It wasn't cheap but it's great for low-value torque settings.
    I've been through a few low-range (sub 50Nm) torque wrenches and was never really happy with any of them.
    Either do it by feel or invest in an expensive tool...

  17. I was looking in a factory manual for something else
    and I came across these low torque figures -

    Manifold screw ( vacuum take-off ) ..... 5 Nm
    Water hose clamps ..... 2.5 Nm

    That beats what I said in an earlier post about the lowest I've found .

    Anybody else seen any super-low torque specs from manuals ?
    :bucktooth:
