3. Mark the top link(s) of the timing chain.

4. Have an assistant hold the crankshaft sprocket with a suitable tool so it cannot turn.

5. Place a machinist's scale above the timing chain (camshaft sprocket) to measure its movement.

6. Put a torque wrench and socket on the camshaft sprocket bolt.

7. Apply a maximum of 20 Nm {2 kgf-m, 15 ft-lbf} torque in a clockwise direction.

8. Note the location of the marked link on the scale.

9. Apply a maximum of 20 Nm {2 kgf-m, 15 ft-lbf} torque in a counterclockwise direction while measuring the amount the marked link moves.
