If you have everything stripped down and can see the crank shaft gear, you will notice an arrow stamped into one of the gear teeth.
this arrow must point towards the bottom, you will notice a mark (notch) cut into the housing, line the arrow on the gear with this notch. remove the four 10mm bolts that secure the top cover of the timing belt, gently open the cover (not removing it) to see the Cam Gear. You will not be able to remove the cover because of the design.
There is a bolt at the rearof the lower seat (in the centre) that holdsit in. Its normally hidden by the boot carpet and you may need to fold the seat tops down slightly to get to it too.
