An incorrect setting of the tensioner pulley can cause engine damage PSA 1.6 HDi / BlueHDi, Ford 1.5 TDCi (article no. CT1203, CT1203K1, CT1203WP1)
Teeth have been sheared off the timing belt, the tensioner pulley arrester body is torn and the full load stop is incorporated.
During the tensioning procedure, the hole in the tension indicator is brought into contact with the hole in the arrester body. As a result, the tension is set far too high and the full load stop is incorporated by the recurring clash with the arrester body until it finally tears or aborts.
Solution: The tension indicator must be set centrally in the recess of the arrester at the end of the tensioning procedure. Observe the tensioning direction.
