    cam caps torque setting gs 1000e

    just a quickie for those in the know.... my torque sheet says 1nm on the bolts that hold the cam caps to the head. even on my smallest torque wrench 1 is nowhere to be found.so I used an old school torque wrench, my laverda loving friend says this torque number can not be right and suggested I get a second/third/fourth opinion from you guys and girls....so thanks in advance for any help ..Simon

    those things do like to vibrate loose once in a while. i check them quite often and tighten when necessary. on one bike i put a tiny drop of thread lock on them. we'll see how that works out when it comes time to take them off. usually i just make them as tight as i can by hand.

      1 N-m is only 8.8 in-lbs which is too low. The correct spec is 1 kg-m, or 87 in-lbs.

      Edit: corrected math error.

        Whatever you do, DO NOT TORQUE THEM TO 192 in-lbs. or 16 ft.lbs. because I can guarantee that the first one (and all of the others) will break off!!!!!
        I do not have the spec. in front of me but from memory it is closer to 6.5-7.2 ft. lbs. or 78-86 in.lbs. Get a real click-type in.lbs. torque wrench and find the correct spec.
        that should be in the factory manual that can be found in Basscliff's website.

          Corrected my math error. Should have know better.

          Disagree about the need for a "real click-type torque wrench". Beam type, dial type, click type, all work. The important thing is to have a quality torque wrench that's calibrated. The beam type is the most simple, and they never go out of calibration either. For this reason they are a good choice for home mechanics that don't use their torque wrench every day.

          To measure is to know indeed.

            I believe the correct torque for the GS1000e is 7 Ft pounds.

              ok, you're talking about the cam bearings aren't you? oy.....

              oh well, i just turn my torque wrench down the right number of clicks below the lowest number on the scale. works so far.

                  If you are turning your wrench down below the lowest markings, I would not trust it. In fact, I have never really trusted the upper or lower 10% of the range. Sounds like it's time to invest in a new wrench. Not sure what you would have over there, but here, we would get a 1/4" drive wrench calibrated in inch-pounds, not foot-pounds. Your conversion to Newton-Metres is up to you.

                    I wonder how many cam cover bolts have been snapped over the years by the erroneous insertion in one edition of the Haynes manual of something like 17 or 18 ft-lbs instead of 7 or 8 for those bolts. A simple typ0 causing so much grief.

                      The biggest mistake most people make is allowing oil down into the cam caps threaded hole. When you tighten the bolt, the threads are destroyed by hydraulics.......And Steve is right about the torque wrench range.....Billy
