Hello just dun mine here are diffrent ones but most work like this.. First find the little hole behind starter its very close to the block in the corner, take the starter off if you cant find it,put in a 8mm drill or somthing the right die. rotate engine with socket and ratchit on the belt pully wile pushing in pin it will drop into a hole in he fly wheel thus crank now locked.Remove all plastic crap round belt. cam pully has one hole that is at the bottom when lined up if its at the top remove flywheel pin and rotate 360 degrees this is a plain hole 6mm into the head casting 8mm hole in pully. Then finely 2x8mm bolts that lock the pump pully.The pain is getting off the belt pully thay are tight and the engine is difficult to lock. buy a timing kit thay are not much money it comes with a gadgit to lock engine and all the pins and screws good luck if its any diffrent let me know and i will see if i can help you.......Ivor
