The great difficulty with which fasteners come off on Asian machinery is sometehing to be expected, even on smaller bolts. IMO, it has to do with the fact that Asian threads are still fine on the larger bolts, whereas Germans - Europeans in general - use a coarser thread on the larger ones and it is not as difficult to remove them. The only time I experienced difficulty in removing a bolt, was the crankshaft pully bold on a diesel Audi, because it was treated with the toughest threadlocking compound, that has to be heated to remove the bolt. I used a 1" breaker bar with a jackstand at the extension going in to the grille to meet the bolt, and a cheater pipe about 8' long, upon which I applied my 175 pounds, jumping down on it to finally break it loose. Of course, I had also to have someone inside holding down the brakes with the car in reverse. I was most happy that it was a standard and not an automatic, or I would have had to try holding down the engine with something blocking the flywheel underneath the car... If I would have had a factory manual instead of a Hanes or Clymer, I would have been instructed to heat the bolt up thoroughly before attempting to remove it. --- I found out ex post facto that it had the "Locktite" or German equivalent (usually better). So, could I charge for all that extra time it took to remove the bolt? Of course not. I could only chalk it up under learning experience. Something as large as the fork cap? Use the proper size tool in the first place or suffer the consequences, like you have experienced in this case. I really loathe working on something after someone else has messed it up; don't you?

My vote goes with letting some penetrating oil soak into it for a day or so. -Kyle -Sent from Beaumont, TX, United States On Wed, Dec 30, 2009 at 2:44 PM, oldschoolgwin <[email protected]> wrote: The first one i got off and it took a lot of torque to move it (guessing 80 ft-lbs) but it moved eventually. This one wasn't corroded or cross threaded - just seamed more like it was way over torqued to begin with. I'll try heat with ice cube technology on the cap first. If that doesn't work then i'll max torque it with a 3ft extension bar and hope for the best. Do people have a habit of overtorquing these like to 125 ft-lbs for some reason? Now i can see why dealerships don't like to work on MC's older than 10ys -the lurking unknown?
