RENAULT MOTOR 16 VALVES

Hello, let's see if someone can help me, I have to pee a Renault 16 Gasoline Valves 1.6L of 2002 and I see that camshafts do not wear a key. Someone can tell me the procedure after putting the draft use in the notches of the opposite side to the pulleys, as I must put the dentated strap and press the screws of the pulleys of the camshafts without moving.

The strip is put in the tracera of the cams and fixed with a bolt to the lid, and the crankshaft is removed a Torx screw that is next to the block and a spike is introduced until heating in a draft of the counterweight of the Sigual.
