How do you tighten the timing belt pully on the cam shaft?  The manual is using slots to hold it steady and this one only has small holes.

   The holes should be threaded.Insert the proper sized metric bolt in the holes,and use a bar between the bolts to hold it stationasy while you tighten the bolts securing the timing gear.It will still work if they are not threaded,just use bolts that hold snug in the holes.
  Definately use grade 8 bolts since you will be using a bar on them.

THANKS.
