Toothed Belt Tension, Adjust Notice: Adjustment is carried out with the engine cold - at room temperature. A prerequisite of this operation is that the toothed belt tension has been checked. This means that the crankshaft is at "1st cylinder TDC" (3) and the camshaft pulleys are fixed with KM-853 (2) - see operation "Toothed Belt Tension, Check". |

Adjust Loosen fastening bolt of the toothed belt tension roller (I). Tension toothed belt tension roller at adjustment eccentric in direction of arrow (anticlockwise) until pointer for toothed belt tension roller is located just before right stop (I). Tighten fastening bolt for toothed belt tension roller.
Remove, Disconnect Remove Fixing Tool KM-853.
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). At the same time, the notches on the camshaft pulleys must align with the marks on the cylinder head cover (II). Secure camshaft pulleys again with KM-853. |
|
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 Fixing Tool KM-853.
Inspect Turn crankshaft slowly and smoothly another two rotations (720 ° ) in direction of engine rotation to "1st cylinder ign. TDC" mark and check adjustment of toothed belt tension roller. If the marks do not align, 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 toothed belt tension roller is approx. 4 mm to the left of the notched mark (2). |
Version II |
Pointer (1) for toothed belt tension roller aligns with the "USED" notched mark (2). |
Tighten fastening bolt for toothed belt tension roller - tightening torque 20 Nm / 15 lbf. ft. Remove Fixing Tool KM-853.
Inspect Turn crankshaft slowly and smoothly another two rotations (720 ° ) in direction of engine rotation to "1st cylinder ign. TDC" mark and check adjustment of toothed belt tension roller. |
|
Inspect If the pointer (1) of the toothed belt tension roller does not align with the corresponding mark (2), the adjustment procedure must be repeated.
Install, Connect Install front toothed belt cover - see operation "Front Toothed Belt Cover, Remove and Install". Connect torsional vibration damper to toothed belt drive gear - note installation position - counterhold at the toothed belt drive gear fastening bolt - tightening torque 20 Nm / 15 lbf. ft. |
