To remove the crankshaft pulley and timing chain cover…
To remove the pulley is simple. It’s held on by 6 bolts to the harmonic balancer. It may be necessary to slide something (screwdriver etc) through an access hole to stop the pulley from rotating.
Now to remove the harmonic balancer. A screwdriver through a hole will stop it from rotating. A large bar on the end of the socket will probably be needed, and loosen in the normal (anti-clockwise) direction.
Once the bolt is out the harmonic balancer will just slide off the crankshaft.
Now the timing chain cover can be removed, this is bolted to the block in 4 places.
