    of installing a new clutch in my 81 308 GTSi, and using the Birdman method. I stuffed shop rags in the bottom drop gear, but am unable to break the nut loose using a standard 24" breaker bar. I don't like the idea of heating the nut, or of using an impact. I have a friend with a 6' breaker bar, but am worried about breaking the gear with that much torque. Suggestions please.

    Thanks in advance.

    Klatu.

    I would definitly use heat before a 6' sally bar. If you can get ahold of an induction heater that would be the way to go.

    It has been my experience that I have done more damage with a long breaker bar than an impact wrench when removing extremely tight bolts and nuts. The negative results using a breaker bar are generally a broken bolt/stud.

    It is also best practice to use an impact wrench for removal procedures and a torque wrench for installation procedures. Better tire stores use this practice.

    Brinelling (ie: damage) generally occurs with excessive radial force impact on bearings, but not on rotation force with threads.

    Using an impact wrench for removal of threaded components rarely results in broken bolts or studs, unless the bolt/stud is very small and the torque wrench is set with excessive torque for the size of the component that needs to be removed.

    Unless someone on this forum has had negative results using a torque wrench in this specific situation, I would suggest using an impact wrench of sufficient torque.

    You might want to do an internet search for best practices using an impact wrench. Some of the impact wrench manufacturers have great web sites for proper use and maintenance of their products.

    Good luck,

    I had visions of broken gear chunks flying all over and breaking my new bottle of Bud Lite. Honestly I was concerned with impack shock on the gear with the stresses applied by the rags. With any other motor, I probably would not have had the issue. My experience has been with Fords, Chevys, and Porsches. (the Get a bigger hammer approach). I will probably use the standard 25' torque bar and under as much torge as I can muster, will smack the end of the drive entering the socket once with a reasonably heavy hammer, what we call a single jack. My heavy equipment operators idea. If that does not work, then it will be the torque wrench.

    Hey, no guts, no glory, or maybe no drop gear.

    I shall overcome, and anything that breaks is my problem.

    Many thanks
