Oh, just read Bob's reply about the special crankshaft pulley tool. Forget it. You don't need it. Even with the plugs pulled out you still have enough resistance from the compression stroke to keep the pulley from spinning with an impact wrench. Take it off with the impact wrench. Then snug it up with an impact wrench. Take a BF (BF needs no explanation) screwdriver and slip it through one of the holes the tool was intended for. Wedge it in there such that it touches the block on the other side. Then take out your torque wrench and tighten as per spec. Just be careful. Use a good torque wrench. If it hasn't been calibrated you could over torque it and warp the crank. Create a hard spot on the bearing, or cause that seal to leak. Use common sense. If you need a neighbor to come help you put some extra muscle to it, then stop there.
