I am sorry I cannot type Chinese in my computer.
I don't think you have used the right tool. In the repair shop, mechanics always use air impact wrench, at least 400 lb torque, for this work. If you can put things back together, you can drive it to a shop and ask them to loose it for you first and then tighten lightly only for driving it home. Then you can use your harborfreight tool to open it. Please don't take the harborfreight tools specs seriously. But I have some worries for the remaining work: replacing the seal and re-tightening the pulley, loosing the camshaft pulley for replacing camshaft seal and re-tightening the pulley, replacing oil pump seal and o-ring, possible replacing water pump, setting the belt timing, etc. Some work requires special tools to make it easy. Loosening the crankshaft pulley might not be the last step that may give you trouble since you need to replace all the front seals to stop the engine oil leak(s). May I suggest you find a repair manual as a guide for the work?
Let's come back to the crankshaft pulley. If you do not want to put all back, I think you still have ways to accomplish your work. If you cannot borrow an air compressor and professional grade air gun like ingesol-rand, you can use a 24 volt cordless Craftman impact wrench from Sears. My friend(backyard mechanic) used it to open a 91 Honda Accord and 97 Toyota 4-cyl Camry crankshaft pulleys in my eyes. Another method, use a long handle at least 20 inches chain wrench to hold the pulley and put the handle against the body, use a long 1/2 inch braker bar w/ 19 mm socket and turn it. You should be able to make it loose this way.
Good luck! Hope can help you more.
