Toothed Belt Tension, Adjust Notice: Adjustment is carried out with the engine cold - at room temperature. The timing must be checked as a precondition for this operation. This means that the crankshaft is positioned at the mark "1st cylinder ign.-TDC" (III), the marks on the camshaft sprockets must be opposite one another (I) and are fixed in this position using KM-852 (II) - see operation "Toothed Belt Tension, Check". |

Adjust Release fastening bolt for toothed belt tension roller (I). Tension toothed belt tension roller (I) at adjustment eccentric in direction of arrow (anticlockwise) until pointer for toothed belt tension roller is located just before right stop (I). Hand tighten fastening bolt for toothed belt tension roller.
Remove, Disconnect Remove Locking Tool KM-852.
Inspect At the fastening bolt of the toothed belt drive gear, turn crankshaft slowly and smoothly two rotations (720 ° ) in engine rotational direction to mark "1st cylinder ign. TDC" (III). The marks on the camshaft sprockets must be opposite one another and align with the top edge of the cylinder head (II). Fix camshaft sprockets in position with KM-852. |

Adjust Adjustment of new toothed belt: Partly release fastening bolt for toothed belt tension roller and turn adjuster eccentric, depending upon version, in direction of arrow (clockwise) until:
Version I: |
Pointer (1) for toothed belt tension roller aligns with the notched mark (2). |
Version II: |
Pointer (1) for toothed belt tension roller aligns with the "NEW" notched mark (2). |
Tighten fastening bolt for toothed belt tension roller - tightening torque 20 Nm / 15 lbf. ft. |

Remove, Disconnect Remove Locking Tool KM-852.
Inspect Turn crankshaft slowly and smoothly another two rotations (720 ° ) in direction of engine rotation to mark "1st cylinder ign. TDC" and check adjustment of toothed belt tension roller. If the pointer for the toothed belt tension roller does not align with the corresponding notch mark, repeat the adjustment procedure.
Adjust Run-in Toothed Belt, Adjust: Partly release fastening bolt for toothed belt tension roller and turn adjuster eccentric, depending upon version, in direction of arrow (clockwise) until:
Version I: |
Pointer (1) of the toothed belt tension roller is approx. 4 mm/0.16 in. to the left of the notch (2), |
Version II: |
Pointer (1) for toothed belt tension roller aligns with the "USED" notched mark (2). |
Install, Connect Tighten fastening bolt for toothed belt tension roller - tightening torque 20 Nm / 15 lbf. ft. |
