Removal

 PERFORMANCE ORDER

  1. Uncover heads of cylinders (20).
  2. Turn out spark plugs.
  3. Having turned a cranked shaft in the normal direction, bring the piston of the first cylinder into situation 20 ° after VMT.
  4. By means of blocking cores (01) fix inlet (75) and final (78) camshafts.
