Before reassembling the removed parts, check timing gears (6) for wear. Change, if necessary.
Important
The two timing gears must always be replaced as a pair.
Refitting is the reverse of removal.
When introducing the driven gear (B) check that the tongue (5) is correctly fitted on the timing system shaft, align the gear
slot with the tongue matching the driving gear timing mark (A) with the gear (B).
At the end of the refitting operations, check that washer (3) is staked against nut (4) so as to prevent the nut from working
loose.
