How to remove the engine crankshaft pulley screw
Professional disassembly method is: when removing the engine crankshaft pulley, disconnect the plug, the first check point on the disk to the first cylinder engine, use a special tool (similar to a long bolt, but only a thread) near the bolt head from screw in screw holes, use it against the balance of the cylinder block, crankshaft crankshaft cannot turn, then use large torque wrench can pull down the pulley bolt.
Non-professional disassembly: using a large caliper with two grips to jam a belt plate, and then disassemble with a torque. This will require two people, but it's easy to tear down the pulley.
In general, the lateral deflection of the cylinder body has an alternate hole, usually close to the first cylinder, usually with a plug.
