How do you break the crankshaft bolt so that you can change the water pump and seals for the crankshaft and camshaft Do I need a special tool to hold the flywheel inplace?

Answer 1

Let the engine do the work for you:Put one end of the wrench on the bolt and the other end on the ground. Put your foot on top of the wrench and have your buddy tap the engine over.AnswerIt may be recerse thread? \ An air wrench will work AnswerI like to use the following method. Get a half inch drive socket of the size to fit the bolt and put socket on a breaker bar handle. (Note, it is important to have socket only on the breaker bar with no extension. If you need an extension, then you must remove the pully from the harmonic balancer first. The pully is usually held on by aprox 4 bolts.) Now put the bar/socket on the bolt and position so that the bar rests on the frame on the drivers side of car or front if cross mounted engine. You may need to turn the engine to put a little pressure on the socket so that it stays in place. Now, just lightly touch the starter switch. You will probably hear a loud clanking and the wrench will fall to the floor and make lots of noise. If you did this correctly, you should find that the bolt is now loose and you can turn it out by hand. If not, then try it again. I own air wrenches and this is still my method of choice.

Good luck
