HOW TO REMOVE THE CRANKSHAFT PULLEY NUT

1. Determine first the rotation of your crankshaft pulley whether it is counterclockwise or clockwise .  Remove anything blocking the pulley so you can see the pulley while the engine is being cranked.
2. put a white mark on the face of the pulley so that it would be easy to see the movement of the pulley.
3. remove all the spark plug cables.  Have someone start the engine while you look at the movement of the white mark if  clock or counter clockwise.  If clockwise then....

a.  insert the necessary socket size for that nut.
b. use a handle of the socket that would extend up to the ground level.
c. position that on your right side but it must be inclined.
d. make sure the spark plugs cable are removed, start the engine by jerking.  the nut is expected to get loose.

If this is not effective. this is the second technique.

1.  remove two spark plugs , either 1 and 4 or 2 and 3.
2.  insert a long stick to the spark plug hole.
3. rotate manually the pulley until the stick is at the lowest ebb or it sink to the fullest.  then stop rotating
4. get a small size of plastic rope. Insert that to the two hole of the spark plug untill it gets full.
5. insert now the socket wrench, and try to loosen the nut.

While you are trying to loosen the nut,   the piston will went up and will  compress the plastic rope and the piston cannot anymore continue because it is being blocked by the rope that is the time when the pulley will stop rotating that will give way for you to loosen the nut without the pulley moving.

the 3rd technique.

1..By removing the starter
2, the ring gear of the flywheel can be accessed.
3. put a small but strong box wrench  to the teeth of the ring gear and the other end of the of the box wrench  to the bell housing as a contra force.
4.  loosen now the crankshaft pulley nut
