Question about Cars & Trucks
1992 Mazda Protege 1.8L. Trying to remove the crankshaft bolt so I can change the timing belt. Tried breaker bar/extension pipe/5thgear/brakes combo - forced clutch to slip with my 200 lbs bouncing at 3 and 1/2 feet leverage point. Tried impact wrench at 95 psi, repeatedly, - nothing. Tried breaker bar braced against ground while trying the starter (including while using jumper from another car to be sure there was plenty of power) - nothing. Looking for a special tool to hold the crankshaft by the pulley bolts, but I can only find for mazda up to 1991 - mine's a 1992. Are there more effective tricks I haven't tried? Or does someone know where I can get a STRONG crankshaft bolt removal tool?

You will have to brace the crankshaft somehow, either by way of the flywheel, or the pulley. The trick to getting the bolt to break is "heat". Propane will sometimes work, but it's generally not hot enough. You want to get that bolt glowing if you can, and hit it with air impact then. Be careful not to burn yourself!
I hope this helps you, and I wish you luck on your repair.
