Work sequence
  E13-0136
–  Set camshaft sprocket to mark -arrow A-.
–  Set crankshaft to TDC No. 1 cylinder. The ground or offset tooth on the crankshaft toothed belt pulley must align with the marking on the seal flange -arrow B-.
–  Fit toothed belt. For used belts note direction of rotation.

–  Tighten tensioning roller securing bolt hand-tight. The slot in the base plate -1- must locate around securing bolt -2- .
–  Tension toothed belt by turning the tensioning roller in direction of arrow until the indicator -3- aligns with the groove in the base plate -arrow-.
–  Tighten clamping nut on tensioning roller. Tightening torque: 20 Nm
–  Now turn the crankshaft two turns in engine direction of rotation until it is again at top dead centre No. 1 cylinder.
–  Now the position of the toothed belts and tensioning roller must be checked again.
–  Install toothed belt guard upper and lower parts.
–  Install belt pulley (note fixing arrangement).
–  Refit right engine mounting with new bolts → Chapter, Engine assembly mounting.
